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?
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!
@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.
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
Best guy on tv been watching him for years Nerver fails top man.....
Thnaks for sharing with us. Question: for thiny orizontal lines olso LG TV .what can be wrong on the board?
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!
What would you say horizontal grey lines on upper half are from on a new QHD gaming monitor ?
Nice and simple instructions without a long drawn out story. Good job!
@Tampa Tech Hi, i'm from East indonesia🇮🇩, Timor island near Australia, Good explanation simple clear and easy to do. 👍👍
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 .
I have a Samsung Q60 50 inch it has faint dot lines in bottom left corner to middle horizontally what could that be cheers
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.
I love you man you save me a lot of money I don’t have thumbs up ...
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

is it same to fix the other brand of the tv's like samsung sharp or etc. ?
Question can u change the processer in an lg oiled tv to a better processer
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!
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?
Thank you showed my broth this video and is fixing his TV by himself!!
What the heck you putting in soup bro?
If the lines are solid, it may be the panel?, is it fixable?, thanks
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.
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 we r also facing same issue that is down horizontal lines but we cont repair at home . sugess me what is the issue
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
hi Does this repair also apply to Samsung smart TV s? thanks
What do you think would cause this half the picture on the right side and the other half on the left t con board or the other board not power board if you know let me know please and thank you very much
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.

If I have a permanent vertical line should I even try this? Or should I just check the panel? Thanks in advance
thx very much..but what does it look like ..and were can i get one?
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
how it is that you don't know if it's the t-con board or if it's a bad panel?
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!!!!
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
Can you show how to repair a vertical line on the right side of screen of a lg60pk250?
So it's a permanent line it's a faulty panel. Is there a quick fix for that or we have to inevitably get an entire new panel to replace it?
I have a Samsung PN51D450A2D tv with vertical lines and I replaced the main T con board and still had the same problem but when I removed the cable from the small t con board there was no lines on the right side of the screen and when I tried to use tape or paper to block the lines I ended up with more lines on that side of the screen and when I replaced it I had the same problem as before so my question is what or how do I fix this problem? 3:58
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?
Are cable ribbon replaceable?, If so where can I get one from?
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?

Hi, can all T-CON boards be used on all LED TVs?
Is main board or logic board same as t con board? I have an old Samsung that have red and green vertical lines
How about tv which doesn't have a t con board, what can be the cause of such lines from top to bottom, e.g Hisense?
Do you have a video on have to change a buffer board. It looks like it’s glued or something to the connectors
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?
the title should be changed to how to replace the t-con board on a lg led tv. good work👍
Do you know what causes a Vertical white line with Fading Grey ? & how to fix it!

Hi, how about horizontal streaks that run through the screen? They change color from what's displayed on the color picture test? let's say the picture test is red, the streaks show as yellow? Is that a bad lcd screen? My tv's just 6-month old. Thanks!
I have a question for Sharp Aquos LED TV. It had a horizontal line and its color green combination of the violet one but still a single line.What are we going to do?we have to go to the repair shop right away?
This is my second tv getting the virtical lines off of the screen. Seemed like things were going well I cleaned the connects with alcohol pad and attached back in place. I turned it on and seen the chanel so i turned off and sprayed with air to get clean before I checked it better inside my house. I plugged it in and now nothing. Vizio lights up at bottom and the screen flickers just a bit when turned on but nothing else. Tried to redo the clamps and tried making certain their in right position but still nothing. Guessing it might be gone now. I had to have done something to cause this though. I just don't know what I could have done. Thanks for listening
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. 👍👍👍😁🇮🇪

I have a 65 sanyo that's a few years old. The screen has two permanent red thin vertical lines. But they are in front of the picture.

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 took one of those ribbon cable's off of the tcon board and the lines went away but theres no picture and only backlight is displaying. Does that mean I replace the board?
Thank you. It really helps us. We like to see more videos of this sort, so that we can learn something. Appreciate it.
So, in the end, what was the problem with the T-con board?

I have a Sony KDL-32BX300 and it has no TCON board as far as I can see and based on my research. The problem I am having with this TV is that black/blank screens appear washed out/greyed out, especially when viewed from the side of the TV and I notice a very faint horizontal green streak across the screen when viewed from an angle at the side of the TV. What could be causing this and what component(s) would need to be replaced in order to fix this problem? Keep in mind that I'm not a technician so I don't know how to test boards and whatnot.
good day sir do you have step by step teardown sony kdl 32w674a ?
Is it the same for a Samsung curve tv for the lcd ?
Can you help me? I have a samsung TV and after a while or may be cleaning with cloth my tv screen has now white spots in tv seems in a pattern of backlight !
