Don't have the model on hand as im at work. But I have a jvc 48" that started out having horizonal lines. It was many lines and it would flicker and not be steady. After a little while the lines would go away and the picture would be great. Well we turned down the brightness and now the lines never show. However new problem. After about 20 minutes the screen goes dark. Sound and all still works. Turning tv off and back on and video comes back. But again after 20 minutes screen shuts off.

Hello,
The monitor started off showing flickering thin (1 pixel) lines horizontally every say 3mm..
They are black on the right and gradually fade to nothing on the far left.
They start either after 5 mins or up to 2 hours after so annoying for testing.
They flicker continuously very fast! With a slight pause milli-second every second.
Initially I cleaned the LVDS cable and connected to the T-Con and then it worked fine for 3 weeks but not sure if this was just co-incidence.
I tested each half by removing the first the left flex from... -
All left and right refers to looking from rear of TV (or looking from front with TV upside down)- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

Hello,
I encountered an issue with my TV long before noticing a pattern of alternating red lines. Initially, I replaced the T-Con board, but the problem persisted. After a year, I decided to open the TV again and found some oil leaks around the CPU, RAMs, and LVDS FPC connector, likely from the thermal pads. I reconnected the LVDS connector but still faced the same issue with the alternating lines.
At first, I thought the LVDS cable might be loose. I inspected the cable, found no damage, cleaned the connector, and reconnected it, but the issue remained. This led me to... -
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... -
Hi all
I have lines on the screen...which is an age old problem that can be remedied by watching Youtube videos and getting out the tape.
My issue (after successfully fixing a different sammy tv with a separate tcon board and isolating the side of the panel...):
This tv has an integrated tcon...so it is a bit more confusing when trying to isolate the clocks.
It has a c ribbon and i have taken each end out to see if that will isolate the lines. instead, it makes it much worse ALL over the tv!
So....i don't know what end of the C ribbon to work with...
