I found another TV by the road and took it home to try and fix it. This one has vertical lines as seen in the pic. I've disconnected both of the ribbons going from the tcon to panel one at a time and still see lines. Is the tcon board bad?

Re: Onn 100012586 vertical lines
That would be a bummer. I also disconnected both left and right at the same time from tcon and the lines went away, though I'm not sure if that means anything useful?
Anything i can test or check?Trust me, i used to be an IT guy

Re: Onn 100012586 vertical lines
Google fixing TV with tape, watch video and try to get a picture using tape method.
If you disconnect both tcon boards and lines go away it's because you have nothing going to panel at all so the screen isn't going to do anything without power. You'll see the backlight potentially because the power board supplys that.Comment

Re: Onn 100012586 vertical lines
Y'all will find this interesting too. I tried the tape fix and if the right screen side of the tcon(tape on ribbon cable) is connected the picture does not show and there are lines on the left side which works if only that sides ribbon cable is connected.

Re: Onn 100012586 vertical lines
Small components like that will test short sometimes when they just are supposed to be very low resistance. Make sure that's the case. Like the one with the zero on it should basically test short. What's the other 101 test asComment

Ah ok that makes sense thank you for the info! I'll be pumped if replacing it fixes the TV I just wish i had checked the buffer board or driver board before buying a tcon replacement.Trust me, i used to be an IT guy

by Stanley1843Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesnโt display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed...

by Daren87Hello everyone,
I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the... -
by gpo23Hello,
i order a t-con because i had bad colors on my SONY KDL-40V3000 :
With the new t-con the color are good but there are vertical lines on all the screen :
I've tried the old t-con and it returned to the initial issue (bad colors but no vertical lines)
Is there a way to fix the vertical lines on the new t-con ?
Thank you for your help

Full model of the TV is 65UJ6300-UA.BUSYLOR. TV was given to me by a relative as non-operational so I'm trying to get it working so I have a nice cheap upgrade for my living room. This is my first TV repair so if it sounds a little like I know what I'm talking about, I don't.
TV turns on and has audio, but backlight doesn't turn on. Getting 230v from LED+ to chassis. Also can't see anything with flashlight test. Another forum suggested I replace the LED strips because that's the most common failure on LG TV's and the flashlight test doesn't always show results.

by x_orange90_xJust bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...
