Re: LG 55LH40-UA Black Lines (bad panel?)
Bummer, but I kinda figured it was a bad panel. Just wanted to confirm with the more experienced folks here.
The TV was free so I had nothing to loose and may even gain a bit by parting it out.
thanks guysComment

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 all ~
Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.
When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.
I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped... -
Hello all, I was recently repairing my Samsung 55" UN55JS9000 tv from the common burnt backlight LED's and cracked light guide panel issue. After replacing the LED's and putting the TV back together, I tested the tv and all I was getting was sound but no image. Somewhere along the way (could be related to the next issue) the T-Con board became damaged and after replacing it I have made a little bit of progress but now have bright pink vertical lines and still no image.
The bigger issue .... I took the TV apart again and realized that I likely didn't sit the LCD panel correctly... -

I have seen many youtube videos with guys who put a tape in ribbon cable and TV fixed in a magic way (I have tried without success).
My TV model is: LE46C750R2W

Good afternoon! Does anyone know how to remove these lines? They are very fine lines at the bottom of the panel. I have 2 identical panels, and I have even thought that this brand has this lattice format, although I highly doubt it.
The photo from the YouTube app is where it is best seen.
thanks in advance....
