Thanks Paul! We love your channel and love your passion for DIY repair!
@@TampaTec Great videos!!! I have a Vizio V705-J0365 inch LED that currently has a horizontal line across the screen and vertical lines on only the left side but you can still hear and see the bottom half of the screen.Would all these symptoms be related to a TCONN?
Just cleaning the connectors with q-tips and eye glass cleaner and blowing off the circuit board cleared the multi-colored vertical lines. Wow saved repair and replace costs! Great
Hello, I recently had the same problem shown in the video and I couldn’t figure out how to fix it. Is it certain that if I clean the connectors and the circuit board the fault or problem will be fixed?
@@carlosa.p2775 my question, too
I just wanted to thank you for these very helpful video's. I recently took on a new job in my company. I now repair flat screen TV's and your video's have been a true blessing. Thanks and keep them coming!
that is awesome congrats!
This is the best how-to video on the subject which also mentions slight variants and it was done in less than 5 mins. Definitely subscribing. Thank you!
Nice and simple instructions without a long drawn out story. Good job!
Thank you showed my broth this video and is fixing his TV by himself!!
What the heck you putting in soup bro?
@TampaTec
I have a 2014 Samsung Plasma TV (PN51F5500) that has developed a one pixel wide solid steady green vertical line that goes from top to bottom on the right side of my screen. It does not flicker and it's there no matter the input, coax, hdmi, etc.
I've done a bunch of troubleshooting from voltage checks, to putting pressure or wiggling on the screen flex cables, to inspecting and cleaning board to board ribbon cables, and nothing shows problems or makes any difference to the screen, except for one thing.
When it comes to the two ribbon cables that go from the tcon board to the bottom buffer boards, if I disconnect the left side ribbon cable, so only the right side of the screen gets image, then the vertical line becomes a solid steady blue instead of green. Then when I reconnect the left cable and disconnect the right cable, so only the left side of the screen has image, instead of it being a flawless picture, it has four vertical lines in the picture. Three of those lines are only one pixel wide, and the fourth looks to be two or three pixels wide. The wider line is a purply/black color, two are black, and one is green. Those four vertical lines are closer to the center of the screen and are all spaced about an inch or two apart, but are not equally spaced.
When I reconnect the right cable (so both tcon ribbon cables are connected), everything goes back to as it was before disconnecting any cables, with the screen being flawless except for that green vertical line on the right side of the screen.
I should also mention that about a week ago the tv did a firmware update (2230->2240). I didn't notice any problems between then and now, other than maybe what I would call a bit of slow motion here and there when specifically playing PS4 games, but that very well may be due to just the console and not the tv. I did speak to Samsung about this and they say there's no problem with the firmware and that's definitely not the problem. They also confirmed that the firmware can only be updated and never reverted for some reason.
If I assumed there's not possibly a bug in the updated firmware, then it would seem to me that the likely cause is either tied to the screen itself (including the IC chips on the directly soldered flex cables) or some fault with the main processor board (because the tcon is built into it on this tv). If it were the processor board, then it would cover both a potential hardware or firmware problem with it. The processor board is still costly enough that I can't just wing it and hope it works, but if I can be relatively sure that's the problem, if it is, I will spend the money to keep the plasma going.
I'm curious as to what you think? I know a solid steady colored line typically means a screen issue, but I can get the line color to change by disconnecting one ribbon cable, plus the opposite side of the screen shows lines as well with the other ribbon cable disconnected. It makes me question whether or not it is the screen is actually the problem. Hopefully your experience can give me better guidance as to how to move forward.
Thank you. It really helps us. We like to see more videos of this sort, so that we can learn something. Appreciate it.
Best guy on tv been watching him for years Nerver fails top man.....
I have a Samsung Q60 50 inch it has faint dot lines in bottom left corner to middle horizontally what could that be cheers
I really enjoy so much of what TampaTec does here, they are just the greatest! Someday if I happen to get closer to Tampa from where I'm at (about two hours away now) I want to look you up and shake your hand for all the wonderful advise. Tampatec Rocks! 👍👍👍
sure thing
@@TampaTec I replaced all 4 boards in my vizio e50-d1. And I still have flickering horizontal lines on the bottom of quarter of my screen. I noticed when I disconnect the right ribbon cable from my TV on board the flickering stops, and yes half of the screen is black, but the other half is on and doesnt flicker. Is this a sign of a bad lcd panel?
hey, i expected you to show us repairing the connections or any minor repairs which could have fixed this v-lines issue without replacing the T-con board entirely.
@Tampa Tech Hi, i'm from East indonesia🇮🇩, Timor island near Australia, Good explanation simple clear and easy to do. 👍👍
Tampatec you are the BEST. Great info and instructions!
I tried to let go of one, instead it turned black, not just the one whose screen is on, so it's full black. I try to remove the flexible next to it, the screen is also black just like when removing the first flexible. I greatly appreciate your help, thank you so much
This guy is A REAL tv repairman
I have 1 vertical permanent line. Is this still a bad LCD Screen/ is it possible to make a video showing how to fix it? Love your vids!!!!
Thanks homie I appreciate the information. I have a Samsung and it keeps cutting off and on now it with straight blk with different colors now so I'm trying to see if it's bad or just loses🙏🏽💯🥇💪🏽💙
What would you say horizontal grey lines on upper half are from on a new QHD gaming monitor ?
Thank you .. it’s really knowledgable. I have LG LG 49UB850T-TA which have same problem. There is 6 vertical stable lines and increasing. Can you please tell me if I can fix this by changing the led panel. Here the repair center’s are telling huge price for the repair. Please advise on this .
Thanks for the Info bro..
i just fix my LG tv 32ls3510
i used hot air on my T-com board and clean some flex
thanks to you i just diagnose my TV correctly..
Hey man, was excited to see that you're a fellow NYer until I read further and saw that you're in Tampa now lol. Anyways, glad I ran across your channel (and sub'd) as I just started to get into electronics so youtube has always been my best teacher. Currently trying to fix a vertical line in a Samsung TV. Big project for a total newb but it was donated so no fear lol. Will be checking more of your videos and keep up the great work.
Always enjoy your repair videos. Big thumbs up! Thanks paul. Joel
Great video. My issue is more streaky than firm lines. The picture is gray, wobbles, and for a time would normalize after warming up. Now seems not to be normalizing. Is this also t-tom board or a different issue?
Possibly T-con board or main logic board but need to troubleshoot to be sure. Get TV boards at shopjimmy.com. u can use heat gun or hot air dryer on boards to see which board it is.
Thanks for your videos, they are very instructive. I have a question: my TV Toshiba 50HP66 has 5 lines at the top and one more in the middle of the screen, horizontal lines, any idea of what the solution would be?
I love you man you save me a lot of money I don’t have thumbs up ...
Great vids! Saved me time and money quite a few times since watching!! I have a SAMSUNG which powers up ok but after 20 to 30 mins, once it's warmed up, it develops a slight but VERY noticeable double image making it unwatchable. Tried a New T-con board and cleaned Ribbons and Connectors but still has the same problem! Whats best place to focus on next?
Have you fixed it?
Tampatec you rock.. Really learn a lot from your videos, keep up the good work
thanks Lloyd :)
Am your subscriber from the Philippines. I just want to ask how much is your charge parts & labor for such a job? Many thanks.
Yes please, keep those videos coming!
the title should be changed to how to replace the t-con board on a lg led tv. good work👍
Hi sir i am from India very nice video i like very much
Thanks bro for the tips information about vertical and horizontal troubleshooting
Very informative. I have a 8 yr old Samsung Smart TV that developed 2 vertical lines. This will help me a lot.
Thnaks for sharing with us. Question: for thiny orizontal lines olso LG TV .what can be wrong on the board?
Tv work for few mins then splits to 3 parts. Start flicking a little then turned to 3 parts. Do you think it Tcon board ? It is a Hisense 50 HD 50H5G. I really learned some stuff from your videos. Thank you so much!!
What’s up Tampa Tec. Awesome video. Quick question. I have a Samsung 65” 2 year old tv (2018). I have just noticed 1 Horizontal whiteish line. It is about 1/4 down from the top. Any thoughts? Worth fixing myself? How much will a shop charge? Thank you
Thanks man i was on the edge, but not after this video. now i know my next step in repairing an LG plasma TV.
Thanks for the videos, I have and issue with my son tv, it got a big black spot on the left side, think you can help, that be awesome
Videos are really illustrative and easy to understand. Great work. I have an RCA RTU4300 only connected to a Firestick. When I power on the TV, I get vertical lines (bars) on the entire screen. Wait 2 or 3 minutes and the lines go away ... TV is perfect from that point on. Could this be a problem with connections to the T-Con board?
My Samsung 60" flat screen has a 'vertical 4" pixelized band'. The strange thing is that it sometimes is there and sometimes its not (it comes and goes!). Is this a T-con issue? Thanks!
Ang galing ng technique mo Sir saludo po ako
Hi, can all T-CON boards be used on all LED TVs?
Nice video, i have a question for my samsung 65inch smart tv. I transported it laying screen facing down then after i arrived home only half of screen is working. Can you tell me what parts needed to replace.
Hey man this tutorial is very helpful for me thank you man
From Suriname South America ,,keep up the good work,
👍👍👍 What part goes bad with the T-CON board?
Brilliant, thankyou again for your most helpful vidz. So far ive found bad caps and dry joints and diodes to be the problems. Keep your videos coming, invaluble info - cheers 👍
I have an LG tv that has horizontal lines on the bottom 3rd of the tv that comes and goes. Picture is fine but the lines show up in static form off and one. Will replacing the t-comm board fix it?
Thanks. Saw this was an old one, but my Element Roku TV has thin horizontal lines. They diminish after it warms up but still there. Is this a TCon board?
Got 5lines (different colours) to the left side of my sharp TV was wondering if it was fixable & I guess so after looking at your video. Great video & very well explained as I'm gonna give this a try. 👍👍👍😁🇮🇪
LG 55in 3D vertigo Redline. I've ordered the t-con board from eBay, if that doesn't work I feel very challenged to take all the housing off to inspect for damage on the ribbons. Thank you for your help I would have never gotten this far if it wasn't for you.
how did it go? did ya fix it?
Hi good video. I have Samsung with 4 permanent horizontal black lines. Would this fix work or it needs a new lcd screen? Thank you
Hi tampatec really enjoy your videos and learn from them. I have a Samsung "60" led tv and it has two permanent horizontal lines Is it the panel? Or could it be the tcon board? Thanks in advance.
Good video tampatec I have a 39 inch Philips tv that has red lines on top and at bottom of screen and had just a small visible screen in the middle that's watchable can you tell me what's wrong with my tv I was thinking t-con board but not for sure
Hey TempaTec, what your doing for us is amazing by the way, I have a screen issues I don't understand how to describe it. Is there a way I can share you a video of it or picture so that you can help me fix it
Your videos are really helpful. I have a problem with a 37 inch Westinghouse This tv has a fully whited out screen with black and Grey wide vertical bars it has sound. I replaced the TCon board and no change What else could cause this problem.
Excellent. How much prices of tcon board?
Good video thanks for the helped. I was able to save myself ALOT of money on repair costs or buying a new one
If I have a permanent vertical line should I even try this? Or should I just check the panel? Thanks in advance
Tampatec hopefully you can help. Recently I had an apparent power surge that took out the main board. When I received the new main board I installed and powered up the Samsung QN85 tv and now I have a single vertical black line. (A column of pixels) can this be fixed? And response is appreciated! Thank you
Hello, nice job, if the screen look like that’s, is the video board ? Right, thanks 🙏
Hi
Do you know a web site where i can find T-con for Sony LEDs ?
Many thanks bro.
You’re making a great job...
Woo I really Love your Channel. Is very helpful. We need more of this Videos on RUclips. Congrats!!!
Great Video! I have an LCD sony kdl46-xbr3 with horizontal lines that are blue and pink/reddish. When I plug in the TV it works for about a minute then it starts with those horizontal lines. I also see the green TV power light on the bottom of the TV. What could it be? and can I get the parts?
I have a Samsung 86” that’s 2 years old and I have a 1 pxl horizontal row out on my tv. Any advice. I’ve tried unplugging and replacing the HDMI
Hi , Great job on the info videos you do on fixing flat screen TV's and how to troubleshoot them. I have an RCA L32D10 which i got from a friend. It powers on ok but quarter way from the bottom i get a thin horizontal line the the screen starts to show vertical lines also which makes the video look washed out. I don't know if you ever came across this type of problem but i would like your thoughts an ideas on how i can solve this problem. Thanks in advance any help will be deeply appreciated.
Great video !! I have a solid very thin line across the television but I don’t want to spend 500$ on a new television so I’ve been dealing with the thin line but out of no where a bunch of colored line went across the television almost a foot thick but then go away but eventually come back and I’ve watched videos with people using tape or just cleaning I didn’t know you could purchase a chip board and replace it that easy , I will go back and look up the company you get them from does it matter the make of the television? Do they sell them for all brands
Hi Friend, first of all congratulations for the video. I wanted to ask you for help: I have a problem with my Samsung LE40B530P7WX TV because it has horizontal stripes. I did several tests but nothing. Could you tell me which are the PINs that I have to block with the tape, I can not understand which is the trace of the signal (VCOM, CLKN, CLKP, CPV, STV, VGM ....) that is causing the problem. A thousand thanks.
Really, REALLY helpful video! I've got a TV presenting issues like the top right hand screen in the examples at 1:08, so I'm going to look at replacing the T-Con board. Those examples were really helpful/informative. Top job! Liked + Subscribed. Keep up the good work! :)
Any luck? Im having the same problem
Hello. If I sent you a picture of the lines on my LCD TV could you be able to tell me if it's a bad tcon board or a bad LED panel so I know what to order to replace it?
Is main board or logic board same as t con board? I have an old Samsung that have red and green vertical lines
Your videos are good, but they are mostly replacing parts, not repairing!
I was looking for a vertical line repairs component level trouble shooting and fix.
Thank you however and keep up the good work.🍻
Thanks for the video bro. I tried to fix my TH-L55ET5M with black stripes but failed. anyhow enjoyed the efforts
Hey there - Ive got two monitors that are the same model - LG 34GK950F - one has a cracked screen and the other one has horizontal lines. Do you think I could resolve the problem by swapping the panel from the one with the lines with the cracked one?
I have a insignia lcd NA-50L440NA14 With two horizontal lines going through the screen what could be the problem? I’m pretty good MacGyver repairing things I’m willing to give it a shot
Great video. Was waiting on one like this. Going to try to fix my Inlaws mitsubishi lcd tv
Hi great video. I have question, my TV has a vertical line that is permanent. Initially it was black. But now it seems to be purple. And also can see a shadow line just behind the said line. What could be the reason? TV is Sony 49x7000e
Unreal....the exact problem for my exact tv. THANK YOU!
Hey there my Tech-Guy, I'm from South Africa Johannesburg, my 55" TV has a burnt Cof cable, Wil replacing the T-Con board stil help the problem of a Thick White vertical line on the one side of the TV?? I'm Adrian 👍🏾
I've got vertical lines that go away as the Philips/LG TV warms up. Any ideas? The lines are there when the TV is cold no matter the input source and across the OSD. So I don't really suspect the powerboard or mainboard. T-Con or worse... LCD panel itself.
Also when observing with a magnifying glass and verifying the colors. The blue diodes operate in that vertical line, but red and green burn intermittently on each horizontal line. So from the 1080p screen there are 540 leds operating green and 540 leds red.
What do you think? My first bet is a bad solder on either the connector going to the side with the issue, or a bad solder on the main chip on the T-Con board. Although that might be hoping for better rather than worse, which is the glue on one of those panel cables.
Thanks for your videos they are pretty helpful however what really is the problem when the lines are permanent and without pictures the screen only has green and pink horizontal lines?
Just bought a Toshiba REGZA Cinema Series from family that displayed this issue within after a week of having it. Hopefully this works!
Did it work Morris?
So, based on your comments the flickering horizontal lines on my LG 42LN5300 TV is a problem with the T-Con board. I have no vertical line issues. But, when I went to the ShopJimmy site to order the board, he indicated the problem is the LCD panel, and that I shouldn't waste time or money trying to fix it. Bad LCD panel requires replacing the TV.
Your thoughts?

I have lg ultrawide 29um58-p it has 6-7 multicolored vertical lines at first they were appearing and disappearing but now they are permanent. i opened it up cleaned whatever i can but it seems like thr display is bad at least every expert i went to said that so i guess they are correct. What do you think?
Thanks for sharing..
more power to you and God bless always...
your duty is fantastic
I have horizontal lines .... Sanyo fw50d48f 50" 1080p 60 hz ... The screen is cracked in ONE Area... tv still works great just has VERTICAL LINES (about the length of your arm going vertically) Will this process work for it? Thanks in advance
Hey bro I got a Sony 40 inch and the screen has horizontal, vertical and also like blops of black. I know you probably couldn't give a diagnostics but what would your advice be on what part I should try to replace first ? I don't want to end up paying for all new parts when I could just get one or two or how ever.
Thank you in advance bud
very useful. i will try this with my lg8500 - it has somilar horizontal lines at the bottom of the screen
Thanks.
I have on my tv Samsung UN75F8000AFXZA horizontal & vertical lines on the screen..How to fix it?
Can u make a video on when your tv screen is black and blank and there are no pics or sound but it's a new tv u used for few months?
i have a samsung LN-t4069f that starts off with a grey screen with audio...then as it warms up the picture will come on if i turn it off then on again. ...but after a random time, the picture gets green lines around everything in the picture. like focus peaking on a camera. im going to give your fix a go and see. thanks for posting. i hope it looks like the LG board. thanks for posting this.
Awesome 👍 thank you for saving our family $$$ on "just getting another tv" 😉
thx very much..but what does it look like ..and were can i get one?
Tampatec I have a single horizontal line that runs through my TV. Will a t con board fix it or is it a bad panel?
Same here but vertical and green line and it doesn't go away.
Wow 🤩 really helpful,Wonder if this can work with my TV
hy i did change my t-con 2 times and still get 1 vertical line on screen i did replace to the cable , and still same problem some times after few hr go aways ? can u help me whit that i have a un48j5200 thank you
Check cable connections from tcon board to LCD screen should be boards under the TV bezel.
@@TampaTec ok thanks i am gonna do it now
@@TampaTec hi do u have an e-mail address so i can send u few picture whit my problem , i am try in to fix my tv but same problem
Thanks for share
Would you suggest buying a warranty program for an LG C7 55" TV? What TV's have a better reliability rating that you experience? You can answer if you feel comfortable about an educated opinion. I noticed that this TV has gone from 2999 to 1699 in price. I know that upcoming new tvs are coming out and we passed the black friday to superbowl discounting
🤔 can be worth it, if the repairman can't fix the TV in 3 service calls usually you get a replacement TV same model or newer model. Warranty costs about 10% of the TV, so $1,600 TV that warranty would cost roughly 160. Avg TV repair service cost $200 roughly including parts and labor. Do it yourself TV board replacement cost roughly $100. Remember TV Warranty doesn't cover damage or theft. About 1 out of 10 TVs will fail in 5 years but Toshiba TV have lower failure rate. I see TV failure because of surges, humidity, backlight settings set to Max which burn out the LED strips faster in the backlight. So consumer care will prolong your TV life. Hope this helps. I don't buy TV warranty but if it's free it's for me. Remember every new TV comes with free 1 year factory warranty. 👍 Sub and like if this helped.
@@TampaTec thanks, based on your response/advice I changed/calibrated the settings to my backlight to minimum (the setting recommendations were from Rtings website). I think/know that will save my backlight. Always look for advice from the experts. Also, this Sony 49"800e needs to be calibrated for each HDMI. Reading before buying a TV helps as I didn't know the difference from a VA or IPS for angle viewing. Retailers would never tell you that.
Never buy LG tvs . i bought mine and in less than 3 week it broke. There was a pink line across the screen and it started flickering
