Let's get some Crystal Castles repair thoughts here:
Am looking at a client's Crystal Castles that seems to be non-functioning. Monitor powers up, but turning up the brightness shows me a grey screen with a couple odd-looking black shapes at the bottom edge.
I checked voltages at the connector and they seemed to be there, so I pulled the board and took it home to my test bench. There was a problem with the socket for one of the pokeys, so I replaced it. Built a JAMMA adapter for it and the game comes up and runs fine on the bench. Take it back to the machine and still get the gray screen. Hitting start doesn't do anything (no sound), so I assume it's still dead. I get 5.13 at the chips and 9.9 at the 10.3 test point. Not sure why it's not running if the voltages seem to be good?
