Recapped Gunfight PCB and I can't dial up +5 on the PS, the highest I get is 4.94 and the PCB wont completely boot. I know the game works I just can't get +5 from the PS? Any help would be great. I can get +5.10 without the PCB attached once the PCB is attached it drags it done.
 
Although 4.94VDC is a little low, that should be enough juice to boot the game. Is that voltage taken from the power supply board...or the motherboard? Could also be a bad reset line on the power supply.

That's taken at the motherboard. If I dial it in without the motherboard plugged in it reads 5.10 then drops when read on the motherboard and I can only adjust it up to 4.94.

The kicker is is sometimes starts for a min then resets and never comes back. Switch on and off and then you get garbage on the screen. So yes it does seem like a reset issue, but what could be wrong?

I'll post pics tonight?
 
Pictures of the connections and screen shots that change as the power is adjusted and the machine is powered on and off.
