[@billcarter7934]

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

[@carlosa.p2775]

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?

[@budandbean1]

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! 👍👍👍

[@timamorello7830]

@@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?

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?

[@Kyrbi0]

Informative & well-put-together.

[@derektierney1314]

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. 👍👍👍😁🇮🇪

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.

Did it work

[@moevit7725]

@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.

[@hailyphuc1765]

Thanks you very much!

[@bzibubabbzibubab420]

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

[@fernandoherrera3709]

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.

[@umblikal]

Thank you five minutes ago the repair man was trying to convince me my panel was bad, and after watching your video I'm sure it was tcon board.

Best guy on tv been watching him for years Nerver fails top man.....

Buenas noches bro! Una consulta tengo un LG 55 LM6700 Smart y estaba normal y derrepente le salio una pequeña y fina linea vertical de color azul cuando enciende el TV y cuando luego entro al menu cambia un poco crees que pueda ser por el FLEX? o que recomiendas? Saludos!!

thank you so much you helped me out so much with figuring out my lg plasma t.v. 😅

[@bcgoose73]

Great video thanks! My TV problem seems to not have a solution. When I turn it on, I get a brief white flash and then black screen. This is what I’ve replaced so far (following your tutorials thanks!) but still there’s no picture: Power Supply board - Replaced Main board - Replaced T-Con Board - Replaced LED Strips - Replaced The only other thing I can think of is the actual screen itself, but I’ve done the flashlight test and the logo shows through. It hasn’t been damaged as far as I know, but it does hang above the fireplace. It’s a Samsung 50” TV (50LN5700) and I’d like to get it working now that I’ve spent a bunch on it. Any ideas?

[@renaldoking5847]

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.

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

Great videos and very helpful as I have a Vizio XVT3D650SV and it’s entire screen has vertical bars running across it all over which tells me the screen is fine...and when I plug in my laptop and move my mouse around I see a faint white bar move vertically across the screen where my mouse is accordingly. Would I just need to purchase a new LED controller board and replace it do you think?

[@jasongallimore849]

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

[@ritaweinstein4056]

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?

[@stevenmckeown3222]

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.
