HELP - TGM PCB graphical glitches - Sony ZN2

[geekmiki]

Hi,

My TGM is suddenly having graphical glitches (see pictures).
Not the first time this exact same problem happens. First time was when I just bought it from Japan and was covered by the seller's warranty and it was exchanged.

This is a Sony ZN2 based PCB, which is known for being a pain to repair, but if someone could point me in the right direction I would be very grateful.

Thanks in advance!

Digging this old thread out again.
The problem disappeared after my first post and the board was working for the past 5 years.
Today, the problem appeared again. Same glitches at the exact same locations. Maybe someone here is more familiar with ZN2 boards now.
