Picked up a large PVM haul today! A variety of 14" and 9"'s were all fine, however I'm having issues with the 20" PVM, 20M4E.

When I initally powered it up it displayed fine, then all of the sudden the picture went off. No sounds, no popping, just died. When fed an RGB signal with audio the audio works fine. I have checked the neck and that all seems fine. Didn't want to re-seat it as it is sealed with mastic and would involve me hacking through that. My dad used to be an electric engineer and he's had a quick look and couldn't see anything obvious. I was advised by Zaki that @grantspain might be able to help.

Cheers :)

Honestly, could be any number of reasons.

Since it still powers on, there's probably no 'simple' fix for it (like a blown fuse).
