Thomson 32LM051B6 flickering vertical lines/dots.

[Jooo]

Hi,
Any ideas what's wrong with this Thomson TV? On menus the picture is fine, but when there is signal applied to any ports the picture is full of flickering/flashing dots.
AOC L32W551T is probably the same TV. PSU is full of Chemicons.

I think you need to check the capacitors on the main board about low voltage stabilizers.. and PSU

Here are pics of the boards.
I have started measuring the ESR of the caps on mainboard, but haven't found any bad ones.

Clean and re-seat all connectors.

I cleaned and re-seated the connectors but that didn't repair the problem. I also tried to heat the main board while the TV was on but that didn't make any difference
