Sanyo DP42848 colored vertical lines

[x_orange90_x]

I picked up a DP42848 the other day and to my surprise it wasn't cracked. Instead however it works but has colored vertical lines across the screen, and they also go over top of the OSD. I tried tapping the back of the TV but they did not change or go away. The do however change color and get thicker/thinner if I twist the TV a little bit. Attached is a picture of the lines. Is this a T-CON issue, panel issue, or possibly just dirty/loose LVDS cables? I haven't had time to open it up yet to check the latter.

Check the t-con cables and lvds cable.

If the t-con is located at the bottom of the tv, I would suspect water damage to the panel board, The board the t-con flat cables connect to. That would be my guess

I will check these, thanks!

I finally got time to check out the TV today. I cleaned and reseated the ribbons going from the T-CON to the panel and saw no improvement. While in there I spotted a bad cap on the main video board. I replaced it even though I knew it wasn't the culprit, simply because it needed to be replaced anyways.

Is it even possible for the T-CON to cause these kind of vertical lines? Or is there likely something wrong with the panel itself? As I mentioned before, twisting the screen changes the size and color of the lines.

if twisting the screen changes the lines etc i would suspect bad tab bonds like r_j asks is the t con on the top or bottom of the tv

The T-CON is at the top.

i would wait too see what others think first but then you may have too strip the tv down a bit and put some pressure on the tab bonds and see if they go away its a bit odd the lines are all across the screen though the issues i have seen its just been one section

I know, it's very odd. Every picture I've seen when searching "vertical colored lines" are all screens filled with lines all the way across, or just one half filled. This is an older TV though, so perhaps the tabs are somehow uniformly coming loose. Hopefully someone else can jump in with suggestions.

disconnect one at a time, the tcon to panel cables and see what happens. that may give you a clue about where the problem lies.
