Got a matty that wont synch to an arkanoid board. It will synch ok to my test jig, and the arkanoid board will synch to another monitor. Synch waveform looks pretty good on the scope..Anyone seen this before?
 
The Matsushita has a non-standard input header configuration. Is it wired correctly?

The 6-pin video signal connector's pinouts are (from pin-1 to pin-6)...
1=not used
2= composite negative sync
3=ground
4= blue
5= green
6= red

Yeah.. fraid so.. It uses the 6 pin molex like the EZY.. I made an adapter for working on the EZYs I had, and I tested it with my jamma test board, and it worked.
 
Ok update on this.. The monitor works FINE if you use a separate power supply for it. if you use it on a cab that has a multi-winding (iso & game power) it doesnt synch. Im guessing its a bad filter cap?
