After watching this video,.it convinced me to just buy a new (NON-TCL) tv. I only paid $280 for it. $50 for the strips, at least an hour of time, tools like double sided tape, permanently cutting the reflector, and a high chance of screwing something up. And even if you fix it, chances are extremely likely another strip will go out again unless you replace them all. Learned a lesson though, you get what you pay for. They clearly designed this TV to fail right out of warranty.
But $50 for the strips gets you all new pieces. "chances are extremely likely another strip will go out again unless you replace them all". When you do this repair you replace ALL the LEDs. Because ya, there are 36 LEDs, so 36 chances of failure. Only 1 out of 36 could fail this TV. So, replace them all is what you do.
In what world does someone have the time to repair this ? The initial comment made it sound as though it was a 5 minute job. This is all day affair and there’s a good chance you will break the screen or lose some parts. Really would have preferred a, “sorry man, go find a new TV unless you are an expert electrical engineer”
@@montymiranda299I'm a cheapskate and it beats buying a new one. Only took about an hour and I'm far from an expert. In my opinion it's worth it if you're willing to do the work
Followed all instructions completely....BEWARE!!!!! The front glass is absolutely as fragile as this RUclipsr mentions. Other than that, completed the project, and the repair is very possible.The tv fired right up, screen and all.including about 8 cracks in the glass, andsome dead spots. This guy knows what he's doing. .
I agree about the step of having to remove the scan boards being skipped. Other than that, just followed this video and had perfect results! Back up and running. Nice work.
One very important step was missed. It's important to carefully pop the scan drive boards out of their plastic holders, and being very careful of the ribbons, tape them to the top of the panel with masking tape. One piece on each end of each board will suffice. If you don't do this, you will rip the ribbon cables right off of the screen panel when you lift it out of the frame.
@@salvador8157 Below is a link to the ones i bought on ebay and worked perfectly for my 55S405 www.ebay.com/itm/4C-LB5504-HR-4C-LB5505-HR-LED-Backlight-Strips-for-TCL-55-TV-55UC6426-55S405/224073376842?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2648
This video skips many important steps and repairing your tv is 1000 times harder than they make it appear. I had to just throw my tv away after trying to follow this video.
Years ago I got a tv when I was working the board was damaged I paid 5$ to have it fixed it's not that bad if you know a little bit of this and that the only way I figured out it was the board was because one chip was missing that samsung was a great tv over all
Great walk through. You do miss out a few key parts as stated in some of the comments. The boards at the bottom connected to the ribbons would easily tear if not aware. Also for a glue separator, i used an old plastic spiral notebook cover. Worked like a charm. Glass came off super easy and was set aside until re-assembly. Overall took me about 4.5 hours to complete. Worth it for me. Thanks for the tutorial.
I just finished replacing all the leds in my TCL tv and the main power board from your kit, these video instructions were on the money every thing works perfect just like new! Thanks
Thanks. Fixed my tv. Also listened to another comment to flip board around and tape it to TV. I didn't have suction cups like instructions did but I made two loops using gorilla tape and taping the legs down. Worked perfectly.
This worked perfect to fix the initial problem but I ended up having to junk the tv anyway because the adhesive is quite strong and the screen broke while disassembling. Can’t stress enough how delicate the screen is and even if you follow the steps exactly there’s a risk of breaking it. Oh well, I got the tv for free and only paid 40 for the backlights so I’m not out on too much money.
I am having same trouble with this exact tv . I went to a repair shop and they are charging 220 to repair it . Now I am going to try and fix it myself and save me some money thanks for the video .
Great video. Thanks for not making it long & drawn out. My TCL has a black screen. But if you shine a flashlight directly on the screen, you can see what's playing. So I'm guessing my LED's are out. I think I'm going to get a Samsung. But try this fix and keep it for a spare.
The reflector panel being glued down proves they don't care about their customers other than selling them a TV. They expect them to run out and buy a new one.
Thanks for the video. I just fixed mine!!! Some extra details missed on the video. "Disconnect the Flex board from behind so you can remove the screen properly".
I finally took apart my 55S405. One thing I did notice is that all 8 of the LED strips are NOT securely attached to the back panel. All the screws are tight, but there's a little wiggle room by design. The screw threads are raised just a little bit higher than the LED strip, so there's not enough heat exchange from the LED to the case back plate. I would guess that's the reason these are failing so soon. After testing my LED strips, I found 1 out of 36 LEDs is dead. And wouldn't you know it, it was an LED at the top row where there's the most heat. Before replacing all these strips, I'll be adding some thermal paste/glue to all 8. Each screw could use a washer to fit around the raised thread too to hold the strip more securely. But you'll need 28 washers.
I read your comment before fixing this TV and looked at it too. You are right, aluminum led PCBs barely makes a contact with huge aluminum back plate (supposedly to get rid of the heat). I think that wiggle room is 100% not intentional and is manufacturing error because they did not calculate little metal pieces arising around the hole after you drill it from behind the metal plate. These tiny metal bits adds just enough height so whole assembly is not possible to secure tightly and make a good heat transfer. What I did is I used Dremel and grinded each led srip mounting hole for a few seconds, it was enough to remove those tiny pieces and new (as well as old) led strips screws in very firmly, no need for washers. If you would add thermal paste it might be even a bit overkill, I did not since it looked more than enough heat transfer after this grinding mod. Also in my case I found some black tape used in manufacturing right under where led strip supposed to make a contact, so I removed those pieces to make metal to metal heat transfer (I believe manufacturing error no 2). But also I would recommend to remove that final white reflective sheet without cutting it like in this video so you won't damage it while grinding + it is not that bad to remove at all, I removed it intact without any tools, just keep steady pressure starting from the corner and allow some time for double sided tape to release it, it is even faster than playing with new double sided tape. After I was done I can already feel slight warmth on that huge back aluminum panel from the leds while tv is working. I paid 18$ for complete new led strip set from aliexpress and waited around 2-3 weeks for it to arrive, and the new ones looked the same as originals. And like somebody mentioned somewhere here before don't use any thin plastic piece to remove the glue from the panel, this is super risky, just unclip the top plastic inner filter frame and lift the whole thing.
Okay everybody here's my dilemma I have a TCL Roku TV if I open up the back I only have three parts one strip that comes from the power to the left side of one of the main boards then I have two quarts connecting one is the power from the switch on the bottom the other one is to the speakers everybody I've asked every one of these RUclips things I've looked at nobody has shown me the same TV everything is a LCD and they say that TCL is the same they're not the same I only take off the bottom part and it shows me my three parts and that's it I've got a black screen but I still have sound if anybody has any idea for me what to do please let me know
Another note in addition to the comments below about the scan drive boards: DO NOT fully cut off the reflector sheet segments. Instead of fully cutting away the reflector sheet, I was able to cut a slit along the top edge of the LED strip and slide the strip out, slide the new one in and carefully tape it back together. This is a pretty good video but the editor must've gotten carried away trying to cut it down to 5 minutes. They leave out a few critical steps and useful tips.
I can't just take my Bezzle off because their is strip connected to it? I have the exact TV model you are working on what gives? What do I do with that little peice of tape that is connected to the scan board and bezzle?
Hi thanks so much for the video. Can you tell me how do i know which LED strips are bad, or do i just replace all the strip? my TV has no picture and no sound
Use a flash light shining in the middle of your TV and power it on, if you see the logo when you power your TV on with the flashlight shining on it then the backlight is out. Good luck to you!
very informative. However there's not much said about pulling the glass out. I did this and the magnetic film that is sealed to the glass popped a bubble and a crack looking bubble across it. It is not a broken glass. It is air between the screen and glass shield. Is there a way to fix air bubbles?
I got right to "thin piece of plastic to ensure the adhesive had been removed" and got a small spiderweb crack in the bottom corner of the screen. Either way good instructions. I just screwed up.
It would have been helpful if this video specified to slide the plastic on only one side of the screen. I got a small crack too because I was trying to slide it along the side attached to the bracket. I thought it was just really strong adhesive so I applied a smidge too much pressure and now that corner of the screen is distorted. 🤬
Same here, make sure to read the comments before following this video. Or actually find a better video to follow. The top of the screen is not going to come out like in the video. His has obviously already been removed.
How about replacing the LED strips next time after adding that pink double sided tape. That pink stuff is nearly impossible to remove. Has anyone found a substitute material (black adhesive) that TCL uses to bond most of them in? I would assume it is some type of thermal adhesive
My 50S425 model is suffering from bad LEDs after only 1.5 years of ownership/use. TCL refuses to perform any kind of warranty on my TV that is less than 2 years old. DO NOT BUY TCL.
Wow. Don't know what the magic trick was but they replaced my TV even though it was more than 2 years old. I couldn't have been happier with their service.
@@EP-ni6my Be prepared to replace it or call them again in another 1.5 to 2.5 years, depending on how bright you have your TV set at. How happy should anyone be to have garbage replaced with garbage?
At 4:07 there's no mention of putting back the reflector pieces you cut out while removing the LED strips. Wouldn't this cause less brightness due to less reflection resulting in you to turn up the back light brightness and causing the new LEDs to burn out even quicker than before? Why not use a heat gun to completely remove the reflector sheet? If it's not needed, then why keep it?
@@sirbarky I just tried the heat gun method to remove the reflective paper. For the most part, it worked. The heat actually made the sticky adhesive looser. But, like I do sometimes I go overboard. I used a bit too much heat for too long in one area. The paper is a bit heat wrinkled. But I don't think it will really affect much. The LED lights in their plastic magnifiers are the most source of light. The reflective paper just reflects the light bouncing from the plastic sheet and the edges of the reflective plastic magnifying pieces on the LEDs. So, if you even pulled the reflective sheet out, I'm sure all you'd see is a tiny bit of light reduction.
I have the black screen backlight issue. I can see an image with a flashlight. I had this same issue with a previous laptop that I had and I replaced the inverter board to solve that issue. What parts do I need to repair this TCL 55S405 backlight issue? Will I need the LED light strip? I will buy from you because I think this video is professional and informative. Thank you!
@@jwhitaker1119 Thanks for replying, James. I spoke with TCL Support and they say that I'm out of the warranty by a few days even though I placed the order on December 18th, it shipped December 20th, and I didn't receive or use it until the 23rd, which is the day that I contacted them. So I suppose I'm on my own on this one. I'll give them bad reviews for the rest of my life and recommend everybody to look elsewhere when shopping for a quality, affordable, reliable television that is a good value.
I bought one from bestbuy and mine just crapped out but within the manufacturers warranty. TCL sent someone to fix it and could not fix it. Ugggggh so now I'm waiting on a "recertified" tv of the same model. I'll be going back to LG TVs for now on. Weird how the backlight goes out when I'm changing the inputs to watch tv. I feel like tinkering around with the tv to see what the issue really is coming from.
Followed directions and replaced leds but somehow cracked my screen basically ruining my set so be extra careful with the screen especially if it has glue on the top edge.
Yes, if there are any missing pieces of the reflector your picture uniformly will suffer. Without the entire reflector you would only see the picture infront of where the led is.
Hi Jimmy your video was very helpful on replacing the LED lights. I just wanted to know after replacing the LEDs is the flashing red, blue, white, green lights is normal for rebooting or might I be experiencing another problem?
I have the same thing wrong with my TV, but my model is the 55S405TJAA, When I take off the back, there's not TCon board. Ribbon goes from main board directly into scan drive boards. I've never seen this on any of the models taken apart on youtube. Is it even possible to have a working TV without TCon boards?
My screen on my tcl 55us57 is giving me screen problems. The screen has darker tone to the right and shimmering appearance. Should I replace the boards or the led strips first?
Hey Jimmy if you're still answering questions can you answer this question I have a 55 inch TCL Roku Smart TV. The screen is black and I have sound turns on and off. I've tried the goof ways with the controller five times with the top right button two times left two times right two times up and two times down did it 9 10 times. Then change the batteries try it again nothing, I unplugged it and that didn't work either so if you could tell me what I need to do Roku TCL model number 55 S4 21 if there's any other information please let me know.
Before you pop out the black border going around the TV also run a flat shimmy around it. They added a small amt of glue around this part of my folks TV same TV too. This is upsetting the manufacturer didn't want me fixing it..the screen is cracked.
How's he going to make this video and not say a single word about the ribbon cables attached to the bezel and the screen. Like thats the most important and crucial part of taking it off. I highly recommend watching another video on how to do this before you jump right in like I did lol. On a side note the adhesive underneath my screen was bonded so well it cracked my screen in one spot as I was running the plastic underneath it. The rest up it came right up no issues. If you want to attempt to fix your tv yourself before you buy a new one to try and save money then I say go for it. But its not as easy as this video leads you to believe.
My tv wont turn on and idk why, it just stopped working, I watched a bunch of videos and non of the tips helped, how do I know where the problem is and how to fix it?
Isn't the screen connected to buffer boards? So before you just go removing the bezel and lifting out the screen you'll need to disconnect the boards etc?
So mines just went out few days ago was thinking of trashing it but at same time it's still a good running tv it's just the screen went black only visible when you flash a light on the screen has sound and everything. And is there a sight to order the LEDs?
Ya, this is bullshit. Since when have TVs become a 2 year disposable item? Some people use a laptop more than 10 years. Heck, I'm still using my 50" plasma I purchased in 2010. Everybody should be rightly pissed off at this. I'm pissed off here because I just got a TV in my shop for ewaste, a 55" TCL with a manufacture date of June 2018 with a dead back light. The guy went out and bought a fancy 55" LG 4k. Consumerism doing it's job. Even if I fix this TV for $10, I'm not sure I'd want this shit garbage in my house. It's probably programmed to catch on fire after the 4th year mark if it's still running.
GREAT tutorial. even with the missed step ( I figured it out on my own without damaging anything) Unfortunately I cracked the screen trying to "unseal" it. 100% on me. I have 2 TCL's, now 1. apparently they suck, this one 4 years old. going with Samsung as my 65" Vizio also died in less than 3 years. Miss my Panasonic plasma's that lasted 8 years before I sold them still working.
I just need to replace the screen. Luckily, I found another exact model 55 TCL for free online (backlight was out). I'm guessing the new screen will fit into my tv no problem? Any advice is well appreciated!
Yes make sure that it is a TCL not an LCD TCL Roku does not have LCDs Roku is a smart TV but it only has three parts on the bottom and no one has shown anyway to fix it they always show the LCDs
My tv has a entirely black screen. You can see the screen if you hold a flash light to it. If I need to replace the strips how many strips will I need to replace? When searching for strips I’ve noticed some come in 4pc and 8pc how do I know how many I need. I have a 55in tcl model 55S421
I have a tcl 65s423 tv. When I turn it on I see the tcl screen flash for a part of a second then it goes off. If I look at the screen from an angle I can just make out what the tv is showing. Thoughts on what the issue is?
Sounds to me like the backlights are turning on for a brief moment, then turning off, possibly due to short or open circuit on the LED strip. One way to tell is take a flash light and shine it on the screen while the TV is on. If you see faint images, then your backlight LEDs or backlight power supply may be bad.
Left out crucial parts. Screen cracked while delicately trying to remove glue. Screen won't separate. So now I just blew money on replacement parts and it's broken worse. Thanks
Warning!!! This should be a huge warning at the beginning of the video about disconnecting the scan drive boards and not tearing the ribbons to the panel. This video makes it look like you just pull the panel off. Someone is going to tear the ribbons off. There are some better videos out there about removing the panels themselves
I just did this repair. Although the video didn't say anything about removing the scan boards from the plastic brackets, while i was un-sticking the adhesive it was very apparent that the boards needed to be removed from the brackets. To the less technical this would be a crucial step to know. Hopefully people read these comments first
@@ePetanovich It has been a while since I did the repair so I'm a little foggy at this point. I believe I had to remove the scan drive board from the plastic holder, once removed you can flip up the brown retaining tab that locks the ribbon in place
Is this what is needed to fix the tv when it has no backlights? Anyone know an estimate of how much someone may charge to do this? Trying to figure out if I need to buy a whole new tv. Mine is only 1 yr old. I lost the warranty info
I have a 65" TCL, my kid hit the screen and cracked it. When I turn it on, the whole screen is black except for the point of impact, where it shows what I would described as "leaked light". Would you know what I need to replace on it and if it's worth it?
my friend moved his tcl and when he turns it on it comes on then shut out but in a dark room if i take my phone light and shine at screen i can see a little so its not off what would cause the whole leds to go out fan or power supply?
my problem as well, and they said that problem is a "rare case" yet I keep seeing hundreds of people with the same problem smh. My lasted 2 years bro...
I replace one strip a few months ago. My tv went black again. I disassembled it again and found a different strip is now burnt? Is there a specific reason this is happening or should I replace all strips? Will the new strips get burnt out as well? Basically asking if its a problem with all of the factory led strip, or an issue with another component, outputting too much power?
I would guess they have found a way to render these TVs inoperable just outside the warranty period. Capacitors used to be the big tool back in the day, now they just overdrive LEDs to burn them out. I've seen on another TV brand their power supply can sense when just one LED burns out, it will then turn off the whole strip. Kind of like a long string of christmas lights when one bulb dies, you have to hunt to find which one. There are smarter ways to build these, and I'm sure they know all of them. But that defeats their purpose and goal of consumerism.
I have 55P2US TCL, now out of warranty, tech told me is back light issue but they don't get it alone,,, where to buy back light only,,,, not including front panel.
Thanks for the video. I have this TV and it went completely black but if I shine a flashlight on it I can see the picture. So it looks like my backlight went out. But why would all LEDs go out at once? Wouldn't that indicate some sort of power supply issue to the light instead?
Hey Robert, I also have this tv and my lights died last week, just letting you know to save yourself the trouble these LEDs are cheap and similar to low end Christmas lights where they cannot remain lit if one in the chain dies. You could test the internals with a volt meter but there's tons of discussions online confirming the absolute horrible quality of the LEDs. The whole thing seems to be designed to eventually fail.
@@nukaiaahpo335 OK, thanks, I read that too, and if one goes out the whole strip is dead. Terrible design, but at least it makes sense why this is such a common problem.
And another thing, with this model actually it is not that difficult to remove the rear reflective film. They are just lazy and didn't even check to see that the adhesive of is very light on this one. Funny because in another video where the adhesive actually is very strong, they make no such recommendations Do you even repair?
Can Anyone Tell me what the tabs are on the sides of the panel at around 1:52 ? they are not the ones on the bottom but on the sides? what are they and are they easily damaged ? do i have to worry if i bent 1 a little ? Thanks
I have a tcl 55" tv model:55UP120 It has audio and I did the flashlight test to see that I have picture as well but I don't know if the strips are bad or what?
These shithead manufacturers use cheap LEDs and drive them with more power than they're designed for to get that extra brightness people want. LEDs last a long time. Pfft, not if you overdrive them with voltage.
I’m going to use one of these broken TVs as a light source. How many watts do the LEDs consume? I would prefer to use a small power supply and not have to use the TVs internal power board which consumes around 60 watts to power the entire tv.
Meh, not so bad. All you really need is patience and time. If you can calm yourself down to a few hour period, them you're set. Slow down, analyze and think. As with any repair, just think about the task at hand. And seriously, just slow down your thinking. You need to focus. When you can focus on repair, it's done before you even start. Stop thinking about all the crap in your life and start thinking about what you're doing now.
My TCL LED40S4900 screen flashes 1 second then goes black but with sound, I've tested all the led strips and all are working, what seems to be the problem?
The back light went out in my 55S405 as well after 2 years. pretty terrible. How do you know that this repair will solve the issue? In other words, What diagnostics can you do to figure out if it is the lights or what's powering the lights? Maybe the wires leading to the lights? While its a good video the work is still delicate and i would hate to sink $50 into a maybe solution.
I've done this repair on a Toshiba TV about a year ago. I've watched other videos showing that most of the time it just takes one LED on the whole strip to put the power supply into shutdown mode. The guy found the bad LED and jumped it with a tiny resistor and fixed it. Me, I'd rather replace the whole strip because sometimes you have 64 LEDs so that makes 63 more chances of an old LED dying again.
@@MeMe-wh7tr yeah happened to me the guy who repaired my TV just replaced 2 leds and soldiered them to the old dead ones causing the TV to give up again in a month. He wanted to charge me 200 dollars again but I opened it and saw what he did when he said he purchased all new led kit. Wish I could take him the old pieces to show him that I know what he truly did.
I cut the panels off of a cereal box and carefully work them under the screen and lift from the top and bottom center. (Never end to end or it can buckle in the center and crack)
On another 55" TV I used those smaller 2.5" suction cups. Two on each end and had one person lift each side. Those smaller suction cups work great. They don't have such a huge bite so there's less stress on the glass, yet they can have a very powerful grip.
I just received my LED strip order and am in the process of disassembling my TCL tv. After removing the scan drive cover, do you disconnect the ribbons cables?
@@MrsNunswife Did you miss the post from Steveh112 a year ago? He mentioned at least one important step. His post starts with "One very important step was missed."
I doubt anyone will reply to this, but why not just melt the adhesive with a blow dryer and remove the whole reflector sheet carefully? Cutting the whole sheet seems like it would affect the picture where the strips have been cut, and using a heat source to melt the glue would fix the issue with it being hard to remove. I'm going to attempt a full led replacement tomorrow and have been puzzling over this. Everyone else I've watched has simply removed the reflector sheet, some tearing it but the picture still seemed ok? This is the one part I'm stuck on how to proceed
The reflector sheet is actually easy to pull of gently. I don't know about a blow dryer since it's made of some sort of plastic or plastic coated paper I think it might warp and cause problems with the picture
@@Andrew-el7or So how about heating the glue from back side, where the metal is? But you'd probably have to remove all the boards from the back plate just to make sure you don't damage the power supply or mainboard.
i have a TCL 55s405 no backlgiths...i removed backlight cable to the ps and i have 0V going out to the backlights connector...i assume its a bad ps but i replace the ps and same issue..ov going out going out to the backlights....shoyuld i have about 65v going out to the backlights? with bl connector disconnected?
factsonfacts..no i have not..i dont mess with leds unless i know for sure thats the issue way too much risk damaging lcd panel..very difficult to get to leds... i asked in a forum and nobody could confirm if i should have voltage present at power supply with leds diswconnected so i aborted the repair until i can confirm its not the power supply...99% of the time its the leds and not ps but i dont care about the tv much right now...do you have 0v coming out from ps to the leds? with connector disconnected?
DO NOT do the section in the video that tells you to run a plastic stick on the top part of the screen to separate the screen, before lifting it out with suction cups. Instead, just un-attach the plastic bevel itself (or whatever you want to call it) together with the screen attached to it, as you will not be able to pry the top right-hand corner off. The screen is super glued by the manufacturer so that it cracks when trying to pry it from the plastic bevel.
Ahhh yes thank you! They left out 2 important steps of the most dangerous part. I got the adhesive out of the left right and bottom, but the top is way more aggresively attached. Also they didn't mention undoing the ribbon cable to that board on the bottom.
@@bagofclothes7360 Don't like how easy they made scraping the glue look? You just run your hand with ease from side to the other, and it's loose. They sure didn't put much effort into making this video. Kind of makes you question the quality of the parts they sell.
Well I'd imagine the LED strips should cost around $20-$40, and the rest is labor. I'd probably charge around 200$ (not quite seeing the process for this TV yet, but I've done this process on another brand), so the guy charging 120$ is an idiot or a sucker for pain.

After watching this video,.it convinced me to just buy a new (NON-TCL) tv. I only paid $280 for it. $50 for the strips, at least an hour of time, tools like double sided tape, permanently cutting the reflector, and a high chance of screwing something up. And even if you fix it, chances are extremely likely another strip will go out again unless you replace them all.
Learned a lesson though, you get what you pay for. They clearly designed this TV to fail right out of warranty.
But $50 for the strips gets you all new pieces. "chances are extremely likely another strip will go out again unless you replace them all". When you do this repair you replace ALL the LEDs. Because ya, there are 36 LEDs, so 36 chances of failure. Only 1 out of 36 could fail this TV. So, replace them all is what you do.
I was 3 weeks past my one year warranty so you are right, these TVs are junk.
In what world does someone have the time to repair this ? The initial comment made it sound as though it was a 5 minute job. This is all day affair and there’s a good chance you will break the screen or lose some parts. Really would have preferred a, “sorry man, go find a new TV unless you are an expert electrical engineer”
@@montymiranda299I'm a cheapskate and it beats buying a new one. Only took about an hour and I'm far from an expert. In my opinion it's worth it if you're willing to do the work
Same thing just happened with mine 6 months and already went out
Followed all instructions completely....BEWARE!!!!! The front glass is absolutely as fragile as this RUclipsr mentions. Other than that, completed the project, and the repair is very possible.The tv fired right up, screen and all.including about 8 cracks in the glass, andsome dead spots. This guy knows what he's doing. .
I agree about the step of having to remove the scan boards being skipped. Other than that, just followed this video and had perfect results! Back up and running. Nice work.
One very important step was missed. It's important to carefully pop the scan drive boards out of their plastic holders, and being very careful of the ribbons, tape them to the top of the panel with masking tape. One piece on each end of each board will suffice. If you don't do this, you will rip the ribbon cables right off of the screen panel when you lift it out of the frame.
Just got to this point in the video and was so confused. Thank you so much!

This video skips many important steps and repairing your tv is 1000 times harder than they make it appear. I had to just throw my tv away after trying to follow this video.
I mean if the tv was already broken then you had to replace it anyways lol at least they have a guide to try and help you
After I seen you needed suction cups, I knew I'd just needed to buy a new one
Years ago I got a tv when I was working the board was damaged I paid 5$ to have it fixed it's not that bad if you know a little bit of this and that the only way I figured out it was the board was because one chip was missing that samsung was a great tv over all
Great walk through. You do miss out a few key parts as stated in some of the comments. The boards at the bottom connected to the ribbons would easily tear if not aware. Also for a glue separator, i used an old plastic spiral notebook cover. Worked like a charm. Glass came off super easy and was set aside until re-assembly. Overall took me about 4.5 hours to complete. Worth it for me. Thanks for the tutorial.
I just finished replacing all the leds in my TCL tv and the main power board from your kit, these video instructions were on the money every thing works perfect just like new! Thanks
Thanks. Fixed my tv. Also listened to another comment to flip board around and tape it to TV. I didn't have suction cups like instructions did but I made two loops using gorilla tape and taping the legs down. Worked perfectly.
Just finished doing this. It was a pain in the ass but I got it working again. Thanks a ton mate
Fs mate
CAN YOU DO MINES
This worked perfect to fix the initial problem but I ended up having to junk the tv anyway because the adhesive is quite strong and the screen broke while disassembling. Can’t stress enough how delicate the screen is and even if you follow the steps exactly there’s a risk of breaking it. Oh well, I got the tv for free and only paid 40 for the backlights so I’m not out on too much money.
I am having same trouble with this exact tv . I went to a repair shop and they are charging 220 to repair it . Now I am going to try and fix it myself and save me some money thanks for the video .
@Jesse Davis how much you paid for the less and did you replace all of them??
Great video. Thanks for not making it long & drawn out. My TCL has a black screen. But if you shine a flashlight directly on the screen, you can see what's playing. So I'm guessing my LED's are out. I think I'm going to get a Samsung. But try this fix and keep it for a spare.
The reflector panel being glued down proves they don't care about their customers other than selling them a TV. They expect them to run out and buy a new one.
Plus the glue they used to hold the LCD panel down, visible at 1:37.
Thanks for the video. I just fixed mine!!! Some extra details missed on the video. "Disconnect the Flex board from behind so you can remove the screen properly".
I finally took apart my 55S405. One thing I did notice is that all 8 of the LED strips are NOT securely attached to the back panel. All the screws are tight, but there's a little wiggle room by design. The screw threads are raised just a little bit higher than the LED strip, so there's not enough heat exchange from the LED to the case back plate. I would guess that's the reason these are failing so soon. After testing my LED strips, I found 1 out of 36 LEDs is dead. And wouldn't you know it, it was an LED at the top row where there's the most heat.
Before replacing all these strips, I'll be adding some thermal paste/glue to all 8. Each screw could use a washer to fit around the raised thread too to hold the strip more securely. But you'll need 28 washers.
I read your comment before fixing this TV and looked at it too. You are right, aluminum led PCBs barely makes a contact with huge aluminum back plate (supposedly to get rid of the heat). I think that wiggle room is 100% not intentional and is manufacturing error because they did not calculate little metal pieces arising around the hole after you drill it from behind the metal plate. These tiny metal bits adds just enough height so whole assembly is not possible to secure tightly and make a good heat transfer. What I did is I used Dremel and grinded each led srip mounting hole for a few seconds, it was enough to remove those tiny pieces and new (as well as old) led strips screws in very firmly, no need for washers. If you would add thermal paste it might be even a bit overkill, I did not since it looked more than enough heat transfer after this grinding mod. Also in my case I found some black tape used in manufacturing right under where led strip supposed to make a contact, so I removed those pieces to make metal to metal heat transfer (I believe manufacturing error no 2). But also I would recommend to remove that final white reflective sheet without cutting it like in this video so you won't damage it while grinding + it is not that bad to remove at all, I removed it intact without any tools, just keep steady pressure starting from the corner and allow some time for double sided tape to release it, it is even faster than playing with new double sided tape. After I was done I can already feel slight warmth on that huge back aluminum panel from the leds while tv is working. I paid 18$ for complete new led strip set from aliexpress and waited around 2-3 weeks for it to arrive, and the new ones looked the same as originals. And like somebody mentioned somewhere here before don't use any thin plastic piece to remove the glue from the panel, this is super risky, just unclip the top plastic inner filter frame and lift the whole thing.
Okay everybody here's my dilemma I have a TCL Roku TV if I open up the back I only have three parts one strip that comes from the power to the left side of one of the main boards then I have two quarts connecting one is the power from the switch on the bottom the other one is to the speakers everybody I've asked every one of these RUclips things I've looked at nobody has shown me the same TV everything is a LCD and they say that TCL is the same they're not the same I only take off the bottom part and it shows me my three parts and that's it I've got a black screen but I still have sound if anybody has any idea for me what to do please let me know
Another note in addition to the comments below about the scan drive boards: DO NOT fully cut off the reflector sheet segments. Instead of fully cutting away the reflector sheet, I was able to cut a slit along the top edge of the LED strip and slide the strip out, slide the new one in and carefully tape it back together. This is a pretty good video but the editor must've gotten carried away trying to cut it down to 5 minutes. They leave out a few critical steps and useful tips.
Why shouldn't it just be cut the way he did it?
@@wesker877 so you get a better fit and retain the original reflector which is probably beneficial to the end picture/results.
Jimmy what do you typically charge for a service like this. Tcl 55S405
I can't just take my Bezzle off because their is strip connected to it? I have the exact TV model you are working on what gives? What do I do with that little peice of tape that is connected to the scan board and bezzle?
Nice technique using the suction cups. Not fully engaged, but enough to lift the screen.
Hi thanks so much for the video. Can you tell me how do i know which LED strips are bad, or do i just replace all the strip? my TV has no picture and no sound
Use a flash light shining in the middle of your TV and power it on, if you see the logo when you power your TV on with the flashlight shining on it then the backlight is out. Good luck to you!
Tcl should just make better TVs that doesn’t break after a year! This is definitely not an easy fix.
what size "dent pullers" do you use to remove the screen? sellers on Amazon are bundling the LED's with 2.5"
Hello I want to change the kit of led lights, could you tell me if they are the same lights as the thomson 55uc6406.?Thank you
very informative. However there's not much said about pulling the glass out. I did this and the magnetic film that is sealed to the glass popped a bubble and a crack looking bubble across it. It is not a broken glass. It is air between the screen and glass shield. Is there a way to fix air bubbles?
i have found out and there's not a fix, tv going to the trash.
I got right to "thin piece of plastic to ensure the adhesive had been removed" and got a small spiderweb crack in the bottom corner of the screen. Either way good instructions. I just screwed up.
It would have been helpful if this video specified to slide the plastic on only one side of the screen. I got a small crack too because I was trying to slide it along the side attached to the bracket. I thought it was just really strong adhesive so I applied a smidge too much pressure and now that corner of the screen is distorted. 🤬
Same here, make sure to read the comments before following this video. Or actually find a better video to follow. The top of the screen is not going to come out like in the video. His has obviously already been removed.
Thank you very much, I followed these to fix my 55s405.
Where did you find the led strips for the 55s405?
@@danielcarroll6010 I bought mine on ebay. I think Amazon also had a few ~$40-50.
Very instructive video. Great shop for parts. Worked great for me. Nice work!!
How about replacing the LED strips next time after adding that pink double sided tape. That pink stuff is nearly impossible to remove. Has anyone found a substitute material (black adhesive) that TCL uses to bond most of them in? I would assume it is some type of thermal adhesive
My 50S425 model is suffering from bad LEDs after only 1.5 years of ownership/use. TCL refuses to perform any kind of warranty on my TV that is less than 2 years old.
DO NOT BUY TCL.
Wow. Don't know what the magic trick was but they replaced my TV even though it was more than 2 years old. I couldn't have been happier with their service.
@@EP-ni6my Be prepared to replace it or call them again in another 1.5 to 2.5 years, depending on how bright you have your TV set at. How happy should anyone be to have garbage replaced with garbage?
At 4:07 there's no mention of putting back the reflector pieces you cut out while removing the LED strips. Wouldn't this cause less brightness due to less reflection resulting in you to turn up the back light brightness and causing the new LEDs to burn out even quicker than before? Why not use a heat gun to completely remove the reflector sheet? If it's not needed, then why keep it?
I just commented something similar before seeing your comment. I think I'm going to try using a hair dryer and see what happens
@@sirbarky I just tried the heat gun method to remove the reflective paper. For the most part, it worked. The heat actually made the sticky adhesive looser. But, like I do sometimes I go overboard. I used a bit too much heat for too long in one area. The paper is a bit heat wrinkled. But I don't think it will really affect much. The LED lights in their plastic magnifiers are the most source of light. The reflective paper just reflects the light bouncing from the plastic sheet and the edges of the reflective plastic magnifying pieces on the LEDs. So, if you even pulled the reflective sheet out, I'm sure all you'd see is a tiny bit of light reduction.
if the screen filter gets scratched or dented does it have a affect on picture at all?
I have the black screen backlight issue. I can see an image with a flashlight. I had this same issue with a previous laptop that I had and I replaced the inverter board to solve that issue. What parts do I need to repair this TCL 55S405 backlight issue? Will I need the LED light strip? I will buy from you because I think this video is professional and informative. Thank you!
If purchased less than a year ago TCL will replace for free
@@jwhitaker1119 Thanks for replying, James. I spoke with TCL Support and they say that I'm out of the warranty by a few days even though I placed the order on December 18th, it shipped December 20th, and I didn't receive or use it until the 23rd, which is the day that I contacted them. So I suppose I'm on my own on this one. I'll give them bad reviews for the rest of my life and recommend everybody to look elsewhere when shopping for a quality, affordable, reliable television that is a good value.
Also, it seems like a lot of people start having issues TCL televisions just a few days past the warranty. Pretty fishy in my opinion...
I bought one from bestbuy and mine just crapped out but within the manufacturers warranty. TCL sent someone to fix it and could not fix it. Ugggggh so now I'm waiting on a "recertified" tv of the same model. I'll be going back to LG TVs for now on. Weird how the backlight goes out when I'm changing the inputs to watch tv. I feel like tinkering around with the tv to see what the issue really is coming from.
Followed directions and replaced leds but somehow cracked my screen basically ruining my set so be extra careful with the screen especially if it has glue on the top edge.
Is there much of a picture difference if you just remove the entire reflective sheet?
Yes, if there are any missing pieces of the reflector your picture uniformly will suffer. Without the entire reflector you would only see the picture infront of where the led is.
Hi Jimmy your video was very helpful on replacing the LED lights. I just wanted to know after replacing the LEDs is the flashing red, blue, white, green lights is normal for rebooting or might I be experiencing another problem?
SUPER STEP BY STEP OPENING COVER TRICK THANK YOU
Can you point me in right direction.. looking for a new display panel for one of these. Are there any good suppliers for them?
how do you remove the outside bezel on newer 4k tcl's? i have 55r617. it is different
I have the same thing wrong with my TV, but my model is the 55S405TJAA, When I take off the back, there's not TCon board. Ribbon goes from main board directly into scan drive boards. I've never seen this on any of the models taken apart on youtube. Is it even possible to have a working TV without TCon boards?
I think you got ripped of buddy
I have the 32 inch and need led strip do you know where I can get them
My screen on my tcl 55us57 is giving me screen problems. The screen has darker tone to the right and shimmering appearance. Should I replace the boards or the led strips first?
How did the reflector sheet magically become whole after replacing the LED strips?
they just played the beginning of this video backwards.
@@Cazero I wanted to know that too. I was wondering id the put the cut out piece back on?
Hey Jimmy if you're still answering questions can you answer this question I have a 55 inch TCL Roku Smart TV. The screen is black and I have sound turns on and off. I've tried the goof ways with the controller five times with the top right button two times left two times right two times up and two times down did it 9 10 times. Then change the batteries try it again nothing, I unplugged it and that didn't work either so if you could tell me what I need to do Roku TCL model number 55 S4 21 if there's any other information please let me know.
For some reason someone leaned up against my Roku TV and now the screen is cracked (Ugg) It's only 2 years old can I get a replacement screen?
Before you pop out the black border going around the TV also run a flat shimmy around it. They added a small amt of glue around this part of my folks TV same TV too. This is upsetting the manufacturer didn't want me fixing it..the screen is cracked.
How's he going to make this video and not say a single word about the ribbon cables attached to the bezel and the screen. Like thats the most important and crucial part of taking it off. I highly recommend watching another video on how to do this before you jump right in like I did lol. On a side note the adhesive underneath my screen was bonded so well it cracked my screen in one spot as I was running the plastic underneath it. The rest up it came right up no issues. If you want to attempt to fix your tv yourself before you buy a new one to try and save money then I say go for it. But its not as easy as this video leads you to believe.
My tv wont turn on and idk why, it just stopped working, I watched a bunch of videos and non of the tips helped, how do I know where the problem is and how to fix it?
Isn't the screen connected to buffer boards? So before you just go removing the bezel and lifting out the screen you'll need to disconnect the boards etc?
So mines just went out few days ago was thinking of trashing it but at same time it's still a good running tv it's just the screen went black only visible when you flash a light on the screen has sound and everything. And is there a sight to order the LEDs?
Hi, very nice guide. I have a 55S421, and the LEDs seem to be glued, any idea on prying them off without damaging the reflector?
How did you do it??
So I should just get a new one then 😕 that's so much work. How much would it cost to get someone to do it for me?
Mines doing the same almost better just to go buy a new one that’s a lot of fucking work lol
Ya, this is bullshit. Since when have TVs become a 2 year disposable item? Some people use a laptop more than 10 years. Heck, I'm still using my 50" plasma I purchased in 2010. Everybody should be rightly pissed off at this. I'm pissed off here because I just got a TV in my shop for ewaste, a 55" TCL with a manufacture date of June 2018 with a dead back light. The guy went out and bought a fancy 55" LG 4k. Consumerism doing it's job. Even if I fix this TV for $10, I'm not sure I'd want this shit garbage in my house. It's probably programmed to catch on fire after the 4th year mark if it's still running.
GREAT tutorial. even with the missed step ( I figured it out on my own without damaging anything) Unfortunately I cracked the screen trying to "unseal" it. 100% on me. I have 2 TCL's, now 1. apparently they suck, this one 4 years old. going with Samsung as my 65" Vizio also died in less than 3 years. Miss my Panasonic plasma's that lasted 8 years before I sold them still working.
I just need to replace the screen. Luckily, I found another exact model 55 TCL for free online (backlight was out). I'm guessing the new screen will fit into my tv no problem? Any advice is well appreciated!
I'd say you shouldn't have any problems since it's an exact model. Just make sure the insides look similar too, then a screen swap should work.
Yes make sure that it is a TCL not an LCD TCL Roku does not have LCDs Roku is a smart TV but it only has three parts on the bottom and no one has shown anyway to fix it they always show the LCDs
Is it ok to replace the display led even different models but the same tcl brand 55"?
What am I looking for if the backlight LEDs won't light up?
I was successful but this was a major pain in the ass. Don’t know if I would do it again honestly.
My tv has a entirely black screen. You can see the screen if you hold a flash light to it. If I need to replace the strips how many strips will I need to replace? When searching for strips I’ve noticed some come in 4pc and 8pc how do I know how many I need. I have a 55in tcl model 55S421
Hey did you ever replace the LED strips? I literally have the same exact TV model as you
I need a new screen panel not the light strips , can you help me
It's the end of you're TV when the panel goes bad unless you can find another used one with a good panel but have other issues.
Wish I would have read the comments before I ripped the Rubin connectors off the screen. Off to Best Buy
I have a tcl 65s423 tv. When I turn it on I see the tcl screen flash for a part of a second then it goes off. If I look at the screen from an angle I can just make out what the tv is showing. Thoughts on what the issue is?
Sounds to me like the backlights are turning on for a brief moment, then turning off, possibly due to short or open circuit on the LED strip. One way to tell is take a flash light and shine it on the screen while the TV is on. If you see faint images, then your backlight LEDs or backlight power supply may be bad.
Left out crucial parts. Screen cracked while delicately trying to remove glue. Screen won't separate. So now I just blew money on replacement parts and it's broken worse. Thanks
Do you have a source for that particular double sided tape? Thanks!
Well how would i know which strips are bad?
Warning!!! This should be a huge warning at the beginning of the video about disconnecting the scan drive boards and not tearing the ribbons to the panel. This video makes it look like you just pull the panel off. Someone is going to tear the ribbons off. There are some better videos out there about removing the panels themselves
Can you put the link
I just did this repair. Although the video didn't say anything about removing the scan boards from the plastic brackets, while i was un-sticking the adhesive it was very apparent that the boards needed to be removed from the brackets. To the less technical this would be a crucial step to know. Hopefully people read these comments first
@@imobracing7071 Can you explain how to remove those ribbons?
@@ePetanovich It has been a while since I did the repair so I'm a little foggy at this point. I believe I had to remove the scan drive board from the plastic holder, once removed you can flip up the brown retaining tab that locks the ribbon in place

Is this what is needed to fix the tv when it has no backlights? Anyone know an estimate of how much someone may charge to do this? Trying to figure out if I need to buy a whole new tv. Mine is only 1 yr old. I lost the warranty info

Tcl 55P2US needs backlight,,, can I use tcl 55c1cus backlight?
Could this be the issue if when I turn on the TV the ROKU screen flashes on for a moment before going black? Everything still works in the background
No, this is not due to a bad backlight, Google how to factory reset your make and model of tv.
@@iowaoutdoorfamily I did refractory set it and it still had the same issue
I have a 65" TCL, my kid hit the screen and cracked it. When I turn it on, the whole screen is black except for the point of impact, where it shows what I would described as "leaked light". Would you know what I need to replace on it and if it's worth it?
Not worth it in my opinion. Other easy to fix parts is okay.
I will just take the week off and get this thing hammered out no problem …easy peasy
my friend moved his tcl and when he turns it on it comes on then shut out but in a dark room if i take my phone light and shine at screen i can see a little so its not off what would cause the whole leds to go out fan or power supply?
my problem as well, and they said that problem is a "rare case" yet I keep seeing hundreds of people with the same problem smh. My lasted 2 years bro...
@@jacobmatthews my tv also only lasted 2 years. Just went out tonight.
Mine as well 2.5 years. Just today
Nice... So it's agreed here that TCL makes a 2 year lifespan TV. Too bad there couldn't be a class action lawsuit against these thieves.
How many strips this the 55S401 have?
I replace one strip a few months ago. My tv went black again. I disassembled it again and found a different strip is now burnt? Is there a specific reason this is happening or should I replace all strips? Will the new strips get burnt out as well? Basically asking if its a problem with all of the factory led strip, or an issue with another component, outputting too much power?
Probably just cheap LEDs designed to break after so many hours
I would guess they have found a way to render these TVs inoperable just outside the warranty period. Capacitors used to be the big tool back in the day, now they just overdrive LEDs to burn them out. I've seen on another TV brand their power supply can sense when just one LED burns out, it will then turn off the whole strip. Kind of like a long string of christmas lights when one bulb dies, you have to hunt to find which one. There are smarter ways to build these, and I'm sure they know all of them. But that defeats their purpose and goal of consumerism.
I have 55P2US TCL, now out of warranty, tech told me is back light issue but they don't get it alone,,, where to buy back light only,,,, not including front panel.
It worked but I have 1 vertical black line now on the right side. Did I do something wrong ?
yes
Thanks for the video. I have this TV and it went completely black but if I shine a flashlight on it I can see the picture. So it looks like my backlight went out. But why would all LEDs go out at once? Wouldn't that indicate some sort of power supply issue to the light instead?
Hey Robert, I also have this tv and my lights died last week, just letting you know to save yourself the trouble these LEDs are cheap and similar to low end Christmas lights where they cannot remain lit if one in the chain dies. You could test the internals with a volt meter but there's tons of discussions online confirming the absolute horrible quality of the LEDs. The whole thing seems to be designed to eventually fail.
@@nukaiaahpo335 OK, thanks, I read that too, and if one goes out the whole strip is dead. Terrible design, but at least it makes sense why this is such a common problem.
And another thing, with this model actually it is not that difficult to remove the rear reflective film. They are just lazy and didn't even check to see that the adhesive of is very light on this one.
Funny because in another video where the adhesive actually is very strong, they make no such recommendations
Do you even repair?
Can Anyone Tell me what the tabs are on the sides of the panel at around 1:52 ? they are not the ones on the bottom but on the sides? what are they and are they easily damaged ? do i have to worry if i bent 1 a little ? Thanks
I have a tcl 55" tv model:55UP120
It has audio and I did the flashlight test to see that I have picture as well but I don't know if the strips are bad or what?
The strips are bad
These shithead manufacturers use cheap LEDs and drive them with more power than they're designed for to get that extra brightness people want. LEDs last a long time. Pfft, not if you overdrive them with voltage.
I’m going to use one of these broken TVs as a light source. How many watts do the LEDs consume? I would prefer to use a small power supply and not have to use the TVs internal power board which consumes around 60 watts to power the entire tv.
3.3v for each one
I followed all of the steps and cracked the glass running a thin plastic debit card along the edges to try to remove the adhesive. I’m pissed
Step 3 (I can see the direction this is going)
Me: step 4 call a tv repair person. lol
Meh, not so bad. All you really need is patience and time. If you can calm yourself down to a few hour period, them you're set. Slow down, analyze and think. As with any repair, just think about the task at hand. And seriously, just slow down your thinking. You need to focus. When you can focus on repair, it's done before you even start. Stop thinking about all the crap in your life and start thinking about what you're doing now.

Looks like a lot of work with quite a bit that can go wrong for a 300$ TV. Whats the odds that Walmart would just exchange it?
The back light went out in my 55S405 as well after 2 years. pretty terrible. How do you know that this repair will solve the issue? In other words, What diagnostics can you do to figure out if it is the lights or what's powering the lights? Maybe the wires leading to the lights? While its a good video the work is still delicate and i would hate to sink $50 into a maybe solution.
I've done this repair on a Toshiba TV about a year ago. I've watched other videos showing that most of the time it just takes one LED on the whole strip to put the power supply into shutdown mode. The guy found the bad LED and jumped it with a tiny resistor and fixed it. Me, I'd rather replace the whole strip because sometimes you have 64 LEDs so that makes 63 more chances of an old LED dying again.
@@MeMe-wh7tr yeah happened to me the guy who repaired my TV just replaced 2 leds and soldiered them to the old dead ones causing the TV to give up again in a month. He wanted to charge me 200 dollars again but I opened it and saw what he did when he said he purchased all new led kit. Wish I could take him the old pieces to show him that I know what he truly did.
I broken alot of screens with them suction cups I don't trust them I pick the corners up with my hands
I cut the panels off of a cereal box and carefully work them under the screen and lift from the top and bottom center. (Never end to end or it can buckle in the center and crack)
On another 55" TV I used those smaller 2.5" suction cups. Two on each end and had one person lift each side. Those smaller suction cups work great. They don't have such a huge bite so there's less stress on the glass, yet they can have a very powerful grip.

I doubt anyone will reply to this, but why not just melt the adhesive with a blow dryer and remove the whole reflector sheet carefully? Cutting the whole sheet seems like it would affect the picture where the strips have been cut, and using a heat source to melt the glue would fix the issue with it being hard to remove. I'm going to attempt a full led replacement tomorrow and have been puzzling over this. Everyone else I've watched has simply removed the reflector sheet, some tearing it but the picture still seemed ok? This is the one part I'm stuck on how to proceed
The reflector sheet is actually easy to pull of gently. I don't know about a blow dryer since it's made of some sort of plastic or plastic coated paper I think it might warp and cause problems with the picture
@@Andrew-el7or So how about heating the glue from back side, where the metal is? But you'd probably have to remove all the boards from the back plate just to make sure you don't damage the power supply or mainboard.

DO NOT do the section in the video that tells you to run a plastic stick on the top part of the screen to separate the screen, before lifting it out with suction cups. Instead, just un-attach the plastic bevel itself (or whatever you want to call it) together with the screen attached to it, as you will not be able to pry the top right-hand corner off. The screen is super glued by the manufacturer so that it cracks when trying to pry it from the plastic bevel.
Ahhh yes thank you! They left out 2 important steps of the most dangerous part. I got the adhesive out of the left right and bottom, but the top is way more aggresively attached. Also they didn't mention undoing the ribbon cable to that board on the bottom.
@@bagofclothes7360 Don't like how easy they made scraping the glue look? You just run your hand with ease from side to the other, and it's loose. They sure didn't put much effort into making this video. Kind of makes you question the quality of the parts they sell.
Where can you get a LCD screen for these?
Did you find put where to get any
Great work......please how can contact you
Thomson 55UC6306 is almost the same model, so I am making this comment hoping someone will find this video
Company charging 300$ for this. And some individual asking for 120$. How much does it actually cost?
Well I'd imagine the LED strips should cost around $20-$40, and the rest is labor. I'd probably charge around 200$ (not quite seeing the process for this TV yet, but I've done this process on another brand), so the guy charging 120$ is an idiot or a sucker for pain.
Panel glass broke instantly when I got to the step at 1:45. Dammit
Ordered exact item you supposedly used and it looks nothing like yours.
Is this common for this tv for LED to go out?? I will not buy it if so, my Hitachi just did this after only 2 years.
Yes
