LN52A530 right side with multicolored vertical lines

[paulstef]

Hi guys,

I would like to have your opinion on what am I looking at here.

Here is what I tried so far, in none of the below the situations the lines change, at first they look like they are fixed, however after each power cycle they seem to change slightly:

- slightly bending the screen / pressing on tab bond connections
- verified flat cable from t-con
- heating / cooling chips on tab bond cables, t-con board, mainboard

The lines are on top of everything (menu, picture)

Thanks :-)

check the components on the edge board especially at the "boundary" where you see one tab connection is "good" and the one to the "left" (based on photo) is bad along with all there after. Possibly a bad surface mount capacitor or resistance or broken track.

Thanks, unfortunately none of the above. What bugs me is whatever I do the lines don't change while the TV is on but after a power cycle they almost always change slightly, different color, different position...
