Thank you!
Enjoy!
Excellent and thorough explanation. After watching it a second time I was able to determine what I needed for my TV. Just saved a $1500 TV and it is now mounted in my living room. 😊 Thank you!
Glad it helped!
You are the best, sir. Thanks to your clear, step-by-step instructions, I was able to pinpoint main board problem with my Samsung 55JU6500, the exact TV you happened to be working on in one of your videos. Replaced main board and voila--problem solved and I don't have to go out and purchase a new set after all. Keep up the great work you're doing and God bless!
Thank you - glad I can help.
First RUclips channel that I found with some body that I can really under stand and what I really notice is that he actually responds to the peaple very important keep up the good work.
Thanks for the compliment - I just want to help people.
Very good video 👌. You are a good teacher who patiently and thoroughly explains each step giving viewers time to absorb and understand. Thanks for sharing your knowledge!
Thank you so much 🙂
Really enjoyed watching your video! Simple down to earth instructions on how to check for problem parts and it was explained to where anyone with a little bit of knowledge to understand. Thank you
Glad you enjoyed it!
Good to know old school dudes are still out there fixing shit. So many people throw things away and buy new. I always try to fix something if it's broken and sometimes it's cheap and easy.
Thank you
young schoolers too
@@Marqui91 i love dumpster diving and scrapping. i have fixed numerous stuff. my entire home office is supplied by my picking that i haven't paid a dime for. i recently picked up a samsung 65 inch curve tv for 50 bucks. only issue was led light. im going to pick up another 60 inch today for 25. its always the littlest things thats wrong with the tv or any electronic.
Agree..great video
Very helpful information you shared in this video!! Thank you for posting this!!

Great lesson. You made the process very logical.
I'm building up the experience via videos like this one to go ahead and repair my Samsung plasma PN64 set
Glad it was helpful!
Very good and simple instructions to identify which part is bad! Thanks for the cours!
Glad it was helpful!
Way helpful for a "shade-tree" electronics guy like myself. Genuinely appreciate the video. You gave me troubleshooting methods I need. About to get to working on a SAMSUNG LN46A500T1FXZA built in 2008. She cycles to start, but won't. Used to take longer and longer to start, then eventually she wouldn't start. Can hear the relay trying to start up as it cycles and kicks in. Feelin a lot better about cracking the case on this set now. Thank you for the video.
You're welcome!
Thank you for the very informative video. Simple and to the point.
Glad it was helpful!
I HAVE WATCHED SOOOOO MANY VIDEOS TRYING TO DIAG TVS I FIND!!!!! Today sir you just showed me the way i will do so for now on... Thanks my man and I will be messaging you for a little more input..
Glad I could help
Good video.
It's the first video with a lot of knowledge.kepp going like that.
Thank you!
Excellent process of elimination video, Thanks!

You are some sort of wizard! This video has taught me more about flatscreen troubleshooting than I ever dreamed of in a simple straightforward way.
I have fixed 3 flat screen TVs in my lifetime. A new power supply board always fixed it. A few days ago we had a hellacious lightning storm here in Houston. It took out my 75 inch Samsung 4K TV. Using a modified engine hoist from Harbor freight I removed it from the wall, took the back off, did some preliminary checks on the power supply. Fuses were good, no solid state devices were shorted, but I sent away for a power supply anyway. Then I saw your video. I put back the old power supply board and disconnected the connector to the main board. The LEDs immediately lit up. From there I disconnected all the other connections to the main board except for the power supply and the LEDs were dormant. The mainboard was the only thing hooked up to the power supply now besides the LED connection. I'm happy and sad and the same time. Had no idea about the connection disconnection technique, very valuable! The sad part is I already ordered the power supply which is not the problem. Too late to cancel. I just ordered the mainboard a couple hours later. But it was worth it, I would've never thought about this on my own. I am from the old school back in the tube days and my success with flat screens, well, it's not always the power supply! God bless!
glad I could help - thanks.
May I ask, from where do you order your parts?
@@Ta21961 I had ordered TV parts from eBay. Also available in Amazon. In some other RUclips video another store name was also mentioned. When ordering parts make sure the image of the part you are ordering matches exactly as that of your old part in addition to matching the part number explained in this video. Good luck!
Thank you for a fantastic explanation and sharing your knowledge! You are a great teacher

Thank you for showing us this process of troubleshooting! I actually was on the edge of my seat wondering what the problem was, until you mentioned there was no problem. Awww man! 😂😂😂 Now I understand though. Thank you for this brother. I hope to learn more from your videos.
Hello, glad to help. Thank you!
love the video straight forward, going to diagnose a dead LCD with this process wish me Luck !!
Luck
I followed the process as described and was the power supply first problem that didn't show lights ordered replacement and was successful thankyou 🎉
Well done videos by somebody who understands systematic troubleshooting, and how not to go down a rabbit hole. Divide the job in half, see which half changes things and keep going along that path the same way. I commend you sir on your common sense and straight forward approach. This method works on the most complicated systems and also in finding a clog in a pipe - divide and conquer!
Thank you - i wish you well
I'm very sure I heard "trouble shit this" at 5:06 L.O.L. almost spit coffee on that. Excellent video earned my sub and thumbs up.

thank you brother your videos are very helpful i have a samsung 55KS9500 model which turn on and off in a matter of seconds but there is back lights and sounds with no picture. what do you think is the problem because i have called samsung and when they checked they said i have to replace the hole screen.
I would inspect the t-con board. But before i do that i would take a voltage ohm meter and see if i have 12 volts dc on both side of the fuse on that t-con board. If voltage is not found, you have a bad main board and or possible LVDS flat cable. Hit me back - lets see if we can fix this tv. Hit me back

@@antixa90 what is the model number of your tv?
@@antixa90 Hello, sound like you may possibly have a intermittent working main board that may need to be replaced to resolve your issues.
Out of all the possible solutions and DIYs out there. This is thee best one. Do you think that them flex panel cables can at some point become damaged and cause that on and off issue ?
If you go through the process on the video and disconnect the main board from the power supply. Apply power and see if the backlights comes on and stays on. That will determine what direction you should go in next.

Thank you for such an awesome troubleshooting video! You are the bomb! I concluded that my TCON surface mount fuse is blown. Do you have this fuse for sale or can you advise where I can buy it/amp rating? Thanks again I am stoked... regards Vinny D
what is the model number of your tv and the value of the fuse you need. I can help you with that or maybe a new t-con board.
Hi there i am in Canada and I just subscribed to your channel. Watched your Samsung videos and you walk through the circuits very well. I have a few Samsung plasma tv sets and other brands as well. My question is this Are plasma tv sets still worth fixing and are there parts available for doing so. The last Samsung tv was from today and the picture portion is missing but the sound is there. For this set I can certainly get the model number if I am able to go forward with repairs. Name here is Warren
I have parts for Samsung, LG, Panasonic plasma tvs.
Fantastic video would be nice to see you do that on a real broken tv
Glad you enjoyed the video!
Great vid was wondering if you might have any suggestions i have a samsung Ln40b530p7f with everything unplugged from the power board it blows the fuse furthest from where the power cord plugs in thanks in advance for any input you might have
doing the research will call you tomorrow.
GREAT video. Tell us, what if the T-Con was part of the power supply?
No such creature unless you have a all in one board.
Good info
Glad it was helpful!
Thank You.
You're welcome
Genius 🚀
I try hard to help people when I can.
Thank you so much for great video... I’m in a process of diagnosing my Samsung TV model UN49MU7000FXZA, so far what I found is when I disconnect the main board from power supply the back light stays ON without any issues but the minute I connect main board to the power supply the back light glows for a second and turns off automatically. Do you think I should replace the main board, since it’s causing the issues.
One thing I noticed is my tv model doesn’t have separate WiFi Antenna and Tcon board, looks like the newer version integrated these into one main board.
disconnect the wifi and t-con board from the main board and using the remote or the power button, see if you get back light if you don't replace the main board
thanks for video i repaired samsung tv😊
Glad I could help
Hi I have a Samsung t32e390sx which wont turn on at all. Fuse in plug is ok, Taken the back off and all circuit boards seems ok front and back. Would you have any idea what I need to look at next. Thanks
I would follow the instructions on the video.
Hello Again, Just saw a video about loose ground screws on boards. I have two or three screws that will not tighten. Could that cause my problems? What do I do to fix the screws?
find larger screws but you always need good grounding.
I might need a LED panel board for a UN55KU6290F version CJ05. Any idea where to get one?
Don't know. Sorry.
Very thorough walk-through. Do you have an updated version for a Series 8 (UN65RU800DFXZA, Version AA02 / URU800D). Internal configuration is a little different, there are two flat cables, can't find a good place to voltage check the power supply, and the back light behaves differently (almost a slow strobe) when power supply is connected to power but not connected to the main board board. Once the power supply is connected to the main board (with the IR/wireless/flat cables disconnected) the back light comes on bright then dims and stays constant. All seems to be stable unless I plug in both flat cables, and then the system just continually restarts as soon as "Samsung" displays on the screen. Thank you.
So you need to pursue the IR/wireless/flat cables. Disconnect the wifi first and see if the backlights stay on constant if they don't, leave the wifi disconnected and go to the next connection. You are using a process of elimination so eliminate one thing at a time until the backlight stay on constantly. Then you pursue that path. Hope this helps
Hey great video. Just saw your channel now and am subscribed! I do have a question with my tv and was gonna see if you know any ideas on what I should do. My samsung UN49MU6290 TV will not power on and will not show a standby light. I replaced both the power board and the main board. When I disconnect the cable going from the power board to the main board then the backlights will turn on. I checked the voltage from the power supply and the chart says it needs to be 12V and when I have it disconnected from the main board it will show the correct 12v but when I have it connected to the main board it shows 9v. I am not sure what to do next.
Hello, leaving the main board connected to the power supply, disconnect the wifi module and the t-con board. Using the remote power on the tv, If it comes on connect the following parts one by one to see which of the two is killing your back light. That will be the component to replace. Hope this helps
@@Patch1stripeTVParts this model tv doesnt have a separate t con board. I unhooked both the flat cables and the wifi module and it still wont turn on for me.
@@ryanflores7768 did you get backlight when you disconnected the main board from the power supply board?
@@Patch1stripeTVParts yes I do. I think the main board I purchased was bad so I am waiting on a replacement and then I will let you know. Thank you.
Thanks
No problem
So I did the flashlight test I have a picture but no backlight. Would you say that is the address board.
Bad backlights that can be replaced if you have a LED tv.
I fixed my Samsung TV type QE55Q65RALXXN 55 inch , isolating (paper 3 mm wide) some contacts in the flat cable as shown in your fantastic video. Everything is already working for 5 days now, except the st by indicator. Do i be aware of change of fire anytime?
Did you possibly disconnect the standby light connector? Next, sound like you have done nothing that would cause a fire. Fuses in different part of your TV are there to protect your internal electrical circuits.
@@Patch1stripeTVParts
Yes I once disconnected the st by connector but all functions of the remote control work excellently as all functions of the tv. Thank you for your help and fast answer. Greetings from the Netherlands
If I have a Samsung TV (Say, 55") can I use it's Main (Logic) Board with another Samsung TV (Say a 65")? It seems like the LVDS output from the Main board should feed any T-COn board. (is LVDS a standard?) Likewise, can I use a power board from one Samsung TV in a different model Samsung TV?
Not so. Most main boards are unique to its model.
Hi, great tutorial! Perhaps you can give me an advice. Have a UE65MU6179 with a BN41-02568 Mainboard (no additional tcon board) that got damaged during thunderstorm. There was only one HDMI port left working so I replaced motherboard and power board as well with second hand boards from a tv with broken panel. Unfortunately it did not work and now the panel is locked in power cycle every 10 seconds no matter if i use the old or the new boards. I even cannot get it to work with old boards that were working before without power cycle. Also replaced the power cable between power and mainboard without success. The backlights are working stable when I plug out the mainboard but when I plug the mainboard back in the panel is restarting every 10 seconds. I have no other components plugged into the mainboard, no wifi module, no speaker, no panel, only the power cable. How can it be that the panel is in power cycle and does not work even with the original boards that were working before? Do you think this is a firmware issue? How can I get this solved when the display keeps rebooting every 10 seconds?
disconnect the wifi module and see if that affect anything. The main board should have been replaced with the exact part replacement. Something is not adding up. The part number is on the long sticker with the barcode and model number on it. On both main boards the part number should be the same.
I have a reboot loop situation. on for 3 sec.and only shows the channel label and turns off and reboots over and over again. I have troubleshooted everything to the power board only hooked it up to the led lights and this still blink and power down. Can I conclude it is the power supply? or can it be something else like an Eeprom on main board. I have UN55FH6003f. Thank you for all your video and I learn a lot. But not effort obviously.
Both options sound good. make choices at this point and narrow it down. That all I can say on this issue without being there. Hope this helps.
good evening sir. i have SAMSUNG UHD 55 inches model RU55RU7100K when i give power the RED light blinking 2 times continues. how can i know the mother board or power supply has fault.
praneeth fernando You won’t know until you open the back. He actually explained the eliminations process in the first 13 mins.
Wil is correct. You can do this. We are here to help you do it! Let us know how you are coming along.
Thanks Wil for responding. Help is appreciated.
thanks for your great down to earth step by step trouble shooting. my samsung LN32D403E4D screen or sound does not come on, only red light on front comes on. when power button is pushed it goes out and a quiet ding a ling on speakers. I have tried unplugging everything and no change so I am suspecting the main power board. if power is getting to the red light, does that mean power board is ok? Steve
Steve, you have a lcd tv which means no led for the backlight. What I have ran into with this model tv is miniature CFL bulbs powered by ballasts. If either fail, there are no replacement that is new out there. You could have swollen bad capacitors on the power supply that needs to be replaced.
@@Patch1stripeTVParts thanks I was able to find a power supply on ebay for $17 and put it in and bingo the tv works!! I was a bit amazed but your step by step approach of process of elimination made it worth the risk of buying a no return item. now I am getting a remote and a roku to complete it. thanks steve
Great videos!! Im working on a un75ru8000f. Power board voltages are all good, Back light is working and there is sound on power up. I changed out the main board and it was no help, Not sure where to go from here, can you help.
Hello, have you tried disconnecting the wifi module from the main board then apply power to see if you tv comes on? If so, connect a A/V source or antenna to the tv disconnect the t-con board from the main board - power up the tv and see if the tv comes on audio? Let me know what happens.
already tried this, did nothing
This tv has no t-con board only 2 boards.
Is it possible that the firmware that starts the TV is corrupted
Hello From Cameroon! I’ve got the 2012 pretty similar with the one on this video with camera that pops up from the top. It’s a 64”. Couple of days back it started going off. It will stay for a while even when I unplug the power code n plug it again it will take a couple of tries to come on. Today it just went off and won’t turn on no more. No standby light nothing. Any advice?
Hello to Cameroon, from your description of the problem that you are having a big consideration is your tvs' age - 8 years, how much is it played in a day. Next from a tech point of view - when electronic components fail they don't intermittently work and stop working. So with that being said I think you have some cracks in your component soldering connections on your power supply board or main board. Now also, on the large square ic on the main board with the large heat sink attached, there maybe some heat related issues there. One way to start isolating your problem is to use the instruction on the video again and see if you get backlight when you disconnect the main board from the power supply. If the backlights come on, see how long they stay on. If they never cut off, I would disconnect the wifi module and see what happens or replace the main board. If the backlight don't come on, I would reflow suspected bad solder connection or replace the power supply board. Let me know what you find - I will try to help you resolve your problem as best that I can from here.
I have a UN58AU7000FXZX that has greenish screen on right side and normal on left. It is hanging on the wall about 8 feet from a patio door that is open a lot to the salt air. Is this worth spending time fixing it
Hello, I would take the back off the TV and disconnect and reconnect all of the flat cables between the main board and the t-con board if you have one and if you do the same to the two small flat cables connected between the t-con board and the LED panel. This should resolve your problem. If not, swap position of the two small flat cable to see if the green screen goes the side of the screen.
Hello, I have a jvc model lt-58ma887.
My problem is the jvc start up screen will come on for about 1 minute then the tv will shut off.. what part do I need to replace..
Thanks for your video.. I have subscribed to your channel and will order my parts from patch1stripe.
(I help who helps me) thank you again for being thorough and informative
A Samsung tv is a different creature than a JVC, but they are all led tvs. You can have a power supply with bad solder connection or a main board issue - take the power supply out of the tv and look for cracked circuits like describe in my soldering video. Next after reinstalling the power supply board, let the tv play with the back off until it shuts down then unplug the power cord. Now feel on the chips only on the main board to see if you can find one that is hot to the touch in such a short time. If you do find a hot component, replace the main board. From your description, I don't think bad backlights is your problem. Hope this helps.
@@Patch1stripeTVParts thank you for responding 🙏 😊... and the promptness is A1in my book wher I can fix my problem or not, I have shared your information throughout my family's page on Facebook...

Not economical to repair unless you find a broken tv that is the same model that has a good LCD panel.
@@Patch1stripeTVParts whats the price im looking at for a LCD panel?
Thanks for the great info ...now quick question when I plug in the TV I get clicking and red led flashing i can hear it buzz on the left of the power supply board then it shuts down and tries again.. i have no leds lighting up no matter what I disconnect so do I have a power supply problem or an led problem im guessing led because that's my luck... thanks for your time..ps my tv is identical to the one in this video...oh one more thing when I disconnect the main board from power supply board it quits clicking on and off
Well your at 50/50 in your choice of parts to replace. I would choose power supply.
@@Patch1stripeTVParts Funny thing is I went to buy a power supply and the guy asked if it was blinking red in the front i'm like yeah … then he refunded my money and said it's the led or backlight I guess he said that he sells these all the time and people hassle him for a return because it's hardly ever the power supply with that model so i'm going to see if I can do a multimeter test to rule it out if it's the LCD though that would need to be dropped or there would be dead pixels in it before it went black wouldn't you think? I really appreciate you getting back to me my mom has no money and i'd really like to get this fixed for her this was her late husbands TV he always bought the newest stuff that came out when it came to technology..

Did you ever try disconnecting the wifi module to see if that gives you video? If so have you check that little fuse on the t-con board? Are you getting 12volt dc or so one both sides of that fuse? If all this checks out I would consider replacing the main board. Let me know.

I don't have a fuse on my T-Con board but there's one on the power board. My wifi module is connected to the power wires and I don't know how to disconnect it. I can read all the options when I press Menu. I even did a reset on the TV. Still dark picture with sound.

I have a standby light, but no led lights. I have 12.76 volts going to the main board, and 3.5 volts going to the power. Then I checked the volts going to the led plug and have nothing. Soooo, doesn't that lead to a bad power board? And thanks, this was a great presentation leading me around this thing. The Model I'm referring to is a UN60J6200AFXZA Looking forward to a reply and thanks in advance.
When you disconnected the main board from the power supply and applied power to the tv, did the backlight come on?
@@Patch1stripeTVParts No they did not. I have no volts at the plug going to the backlights.
is the heatsink on the mainboard removable? I have a frame 3.0 samsung, endless reboot, untill i freeze the main cpu heatsink then it boots up and works fine till it heats up again.... i want to take apart the heatsink, clean it and either apply tape or paste to see if that gets it working...

What is the first thing I should try or change? I can't see any back light (no holes or white plastic as shown)
backlights
@@Patch1stripeTVParts Thanks
@@Patch1stripeTVParts I tested the backlights with 4 9V batteries connected in serial(36V) and one of the strip is not good. You were right. Thanks.
I’ve watched all your videos, very informative. I have a Samsung UN65KS8000FXZA….the picture and sound just stopped…black pix with intermittent flashes of light from the back lights. Took it to a RV repair shop they said it was the main board…and wanted $500 to repair…couldn’t do that so I ordered a new board, changed it out and the picture came back but is distorted with lines through it, the sound is back as well…so I got a replacement board…and it does nothing…the back lights intermittently flash, no sound with replacement…so I am not sure what to do…could it possible be the t-con board? Already replaced the power supply board and it wasn’t that…I am ready to give up….I am a nurse not a tv repair person…..but the tv was quite expensive and only 4 years old….any recommendations?
How did you determine that you needed to replace your main board other than what the RV repair shop told you? Next, where/who did you purchase your main board replacement from? What is the part number of both main boards? This information is on the bar code label that also have the model number printed on the same label. Let me know this information so that I can help you. Also did you follow the video and disconnect the main board from the power supply and the backlights come on when you apply power?
i have a un55mu6300fxza the tv has in a power on and off loop no show logo when you connect start with that without touch the control. the controller shows blinking 7 times the light and i check the leds and its ok i take out the main from psu and the led stay on. .. what you beleve
Did you try disconnecting wifi module and turn on tv? Did you disconnect t-con board and turn on tv? If your tv did not turn on after disconnecting those two items, you need to replace the main board.
Do u have parts for qled 85 inch samsung?
no we don't
Looking for BN94-07345F...couldnt find it on ur website
The t-con board is probably fine. You have to resolve your mainboard issue first. I think that will solve all of your problems. I will check my warehouse to see if I have that part number. I will contact you in a couple of days.
I need your advice about my un65mu6500f. The screen flashes for a little while and goes off after about 5 seconds it does the same it doesn't turn on or off with the remote control
sound like you have bad led backlight strips. hit me back
@@Patch1stripeTVParts thank you. I didn't do anything I just let off for some days and then it worked again but now sometimes it has stripes on the screen
@@lutesaldivar1617 that's your back lights strips. Some are working and some are not - that causes the stripe effect on your picture. Hope this helps. I sell backlight strips.
I have a Samsung UN40JU6500. The only problem that I have is a flickering screen, otherwise it works well. Is this flickering an LED strip or backlight defect? Can you help me understand how I can narrow the problem down please?....Mike
You really help me to find out I needed a main board for a Samsung tv. Installed it and the tv came on but the color was green and purple. Then I was dumb and went into the secret service menu and calibrated color, tv shut off and would not come on. No red standby light. If I push and hold power button the Samsung sign will come on but then the tv will shut down right away. have I bricked the tv or is there a fix. Any help would be appreciated.
I am a servicer and I never go into the service menu. If you replace a main board with the exact part number - no problems. I would at this point purchase a new board from a good seller and be done with this repair. Think about this, the microprocess you programmed is only on the board that was installed at the time you went into the service menu. Change that board it probably was defected when it arrived.
Hello, I have a Samsung UN50M530DAF. I have replaced the main board to find out it was not the main board. I returned it. I ordered the power board and plugged in the power cable to the rear of the 50" set. No power indicator light in front nor any of the backlight LED are coming on. The red optical digital audio connector light is on. Please let me know what do I check for next. Thank you.
Hello, follow the troubleshooting process on the video. It will take you to the problem.
Is it volts ac that you were checking on your main power supply board.
there are two section that the power supply is divided into - ac power which is converted into dc voltage to power the rest of the electronic device. Stay away from the ac power supply - very dangerous if you are not certified or qualified to troubleshoot. Now the lead connector between the main board and the power supply is dc voltage. Be careful as well. If you think the power supply board is your problem, just purchase a new one and avoid the complications.
I have the newer Samsung T-con in the mainboard TVs. When I plug both ribbons from main to the LCD address panel , my TV struggles to stay powered on. When I plug any single 1 of the two ribbons to LCD address , the TV stays on but no picture. So I guess it's the ribbon cables, LCD address board, or something further pulling the TV to power down ?
Any tips on what I should do?
First I would swap the ribbon cables around to see if you get the same results which would eliminate the ribbon cables as being your problem. Next I would let the tv come on and stay on for about 2 minutes then unplug power from the unit and feel for hot or warm components on the main board and the LCD address pcb's. If you find components that are over heating that would be you problem area.
I put a new mainboard and powerboard in so those should be good from overheating issues. I'll buy new ribbon cables and go from there! Not sure at all how to work with the PCB address boards because they connect under the metal case to the screen through some orange film connectors
@@salmannasir793 I am having the same issue. Just happened last night out of the blue. The only thing I did that day was connect a Chromecast to the HDMI and the USB to power it. Did replacing the ribbon connectors solve your issue? Thanks, Salman.
My samsung (LED 46 tv UN46f6800AF) is clicking on/off after sometimes, Any suggestion?
go through the process on the video of disconnecting the main board from the power supply and when the backlights come on, see how long the tv stays on before the clicking starts. If the clicking does not happen, replace the main board.
need some help sir, about my samsung 32 inches led tv, hope you can tell me the problem. to much heat on the other side of my tv, but the other side, top and bottom are all normal, not heating that much unlike the one side, ty for the help, more power on your channel,thanks.
hello, the only thing behind the screen is LED backlight strips. You may have LED strips that are failing and causing other LEDs to draw excessive current. Take the time to remove the LCD panel and see what's going on behind it. It's easy to do with a small panel. Watch my video on replacing backlights for instruction.
Patch1stripe TV Parts ty very much, going to watch your video on replacing led,ty.💋
