I'm looking for help/advice on a WCS I recently acquired. This is my first pin, so I'm not too familiar with everything yet.
It played fine for 2 days, but now very, very randomly, it will shut down during play. The display freezes and stays lit. But everything else shuts off. Game then will power back on. It's odd, and like I said, super random (not related to something happening in game).
Any ideas for me to check? Thank you!

The game is resetting caused by bad/weak +5VDC. See the above for a step by step of the reset troubleshooting.
For grins and giggles, power off, reseat J101, J102 and J114 on the driver board. Turn the game on and play to see if they go away temporarily. If they do, you'll have to replace the headers and connectors eventually. If the resets don't seem to go away C4 and C5 will probably need to be changed.

and also J210 power connector to the MPU.
