Well, I guess the problem is on the main PCB then, I was going to suggest a Greenweld replacement PSUm but if the composite is duff too, this won;t work. I wonder if the crystal is duff? This would certainly screw it up! If its drifted, it could still be working but some sets would be able to cope, while others not. It would explain why it seems OK to the fixers.
