The game is Commando, it has a K7000 series monitor. I've capped the chassis, double-checked the sync, have full continuity on the sync wires all the way from the chassis to the board.
I have to adjust the damn vertical hold every time the game is powered up. It used to be fine, but now only does this....argh!
There are caps on the Commando pcb, is it possible there's some caps related to sync that could be causing this? I have not reflowed the solder joints on the input pins on the chassis yet but have wiggled them to see if they're lose or affect picture.
It's a mystery....any insight is appreciated.
