Panasonic plasma tv TH-42PY800H - intermittent half screen black

[Mika2223]

This TV survived the red screen issues a few years back thanks to the fix suggested by this forum.

Recently it's started to show black screen on the right half intermittently. I tried to re-seat the LVDS cable and some other cables on and around the A board but the problem has become more random.

As the D board is behind the A board, I couldn't reach those ribbon cables there. Would they be the culprits? Or is there any other thoughts?

Here's a pic of the symptom. The whole right half is black at times.

Looks like the lvds cable or its connectors is at fault. Anyone know where to get a replacement?

Nah not the connectors. Half screen is black , i would say mainboard or d board. D board is the small board behind the mainboard , the red connector goes to the d board.

What happens when you apply pressure on the heatsink?

I tried to put pressure on one end of the LVDS cable. At a certain angle/position, the problem can be fixed. Once I leave it, the problem comes back.
