RCA RLED4633B LED TV with lines on it. Here is a pic of the screen. Would this be a t-con issue or LCD panel issue. Any help would be greatly appreciated.

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 posted about this previously but didn't get any response, and I have some troubleshooted a bit so I have more info.
The screen is full of horizontal "gaps" or lines that distort the picture badly, and after about 10 seconds of powering it on the screen starts to fill with red vertical bars that take on the horizontal pattern. After the screen filled with the red bars, they instantly vanished and then slowly started to reappear. I initially thought it was tab bonding failure, but after getting down to them and pressing each one I find zero change in the picture. I went... -
Hi all,
My TV had been showing for the last year some faint horizontal lines on all of its right side, about one out of each 4 of 5 rows of pixels. Not much of a bother, they were unnoticeable when watching a movie. Then, all of a sudden the horizontal lines became much stronger and crossed the whole screen, effectively making it a pain to watch.
I watched some youtube video where some guy "fixes" it with some tape on the ribbon cable of the t-con, so I tried that, but to no avail. Actually, after putting the TV back together again things worsened: apart... -
Hi
Asking for a friend.
I'm used to black vertical line in otherwise good image - probable solution is a rubber to push and tighten the COFs bonding.
but here its the opposite !
TV has new T-con = same issue
A missing panel voltage would have global effect
So , what should one do ? how can I find where the fault is ?
Thanks !... -
Hi all, looking for some input on this one. I've been reading the forums for quite some time but this is my first time posting for help.
LG 47LV5500-UA
10 years old
20,000+ hours on it.
Watching TV on it last week and right while I was watching the image suddenly started experiencing the symptoms in pics. Rainbow chromatic vertical lines and alignment issues. The issue is uniform across the entire panel. It does not come and go, the symptoms are stable.
Here is what I've tried so far:
- Factory reset and cycle of picture options....
