Started doing this intermittently until the TV would be on for a few minutes then picture would display. Now it just looks like this regardless.

Re: LG 55LV9500 no picture wide vertical lines
take the black heatsink off the mainboard BGA chip and heat it up with a heat gun on LOW for 45 seconds. get all of the chip hot and try not to get anything else. It probably will come back to life, for how long........? -
Re: LG 55LV9500 no picture wide vertical lines
so you are saying the processor on the main board needs reworked/reflowed. I can take it off and re-ball it. Is there anything else it could be? Would like to rule out less invasive stuff first.Comment

Re: LG 55LV9500 no picture wide vertical lines
yes. Re-balling would be the best thing you can do. I have half assed re-flowed 15 of the edgelite led tvs. Only one has gone bad. He had it re-balled somewhere and its fine again. You might want to offer a re-balling service, you would get a lot of work from me and others on B.C.Comment

Re: LG 55LV9500 no picture wide vertical lines
never though about offering it. I guess my only issue would I would not be able to verify repair. I would be willing to reball the chip itself and mail back for install to be done by you.Comment

This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.
Problem
TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode... -
5.5 year old 85 inch Sony Bravia X950G started showing gray horizontal lines across the bottom of the screen and the picture shifts slightly vertically when it happens. The lines sometimes get bigger/smaller vertically and bounce back. See the video for the problem. It seems to be happening after it warms up after an hour or so. Happens regardless of source. Right now there's nothing but power cable connected and it's happening. We did hook up a new Nintendo Switch to our HDMI switching receiver today, and played for a while with no issues, but this problem didn't occur til a few hours later while...

Hello, 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 doesn’t 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... -
I'm not sure what to do next and came here since y'all helped me fix a 50" plasma TV back in 2014, which is still working!
A friend gave me an Insignia NS-50DR620NA18 50" TV that suddenly developed large vertical lines on it. He said he had no idea what might have caused it and has replaced it with a larger TV. He was going to throw it away.
I did not notice any bulged or leaking caps on any board, the voltages produced by the power supply match the voltage that the pins are marked. The backlight leds are working. I have tried cleaning the ribbon cables... -
Hello,
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
