I have a Nintendo Vs PCB that continue to reset once the attract screen comes on. I have tried multiple chipsets but the same thing keeps happening. I would like to repair the board myself. Anyone have any experience with resolving this problem? Thanks for any help you guys can give!
 
You need to check the voltages being supplied and make sure they are correct. It could be that your +5v is a bit too low.

If the voltage is the problem, is that on the board? Don't see a pot on the board and all of my other pcbs work just fine in the machine.

I have one PCB that resets sometimes when I turn the system on. The screen flashes and the game keeps rebooting. I can fix the issue by pushing on the chips. I think the PCB has a bad socket.
 
If you have another CPU chip, try it. 80% of the time it's a flaky or bad CPU that's causing behavior like that (in my experience).
