Philips th-42pv70p plasma tv problem

[anno]

Hi.
I have a 42 inch panasonic plasma tv , model th-42pv70p with a problem.
after the tv has been on for 30-45 minutes the picture is getting 'green'.
Best is to show some pictures, i don`t know how to describe it.

There is a cable running from the "A" board, which has the video inputs on it, going to the "D" board which processes this image. The "D" board is underneath the "A" board. Reseat this cable (remove and re-insert both ends) and see if this fixes the issue.

i don`t see the A board. There are 2 boards called H and DG .
the H board has speaker out,sound processor, AV terminal, AV switch.
THe DG board has Digital signal processor, micon, HDMI interface, peaks lite 2.

I see the D Board, it's underneath this boards (H and DG boards). I think you mean this boards?

On this set, DG to D board; it's an older model the newer ones have DG+H in one A board,.
