Quoted from JohnSteed:I first powered up the machine. Most of the lights came on and there were a few red dots on the DMD. No sound, no power to any coils, no display. The LEDs on the CPU were all off.
The LEDs on the CPU off originally was because your 5volts was not there.
The main cause of 5volts going low or game resets is the C2 leaked out and then corrodes the trace under it. So change your C2 (100uf 25v) cap with either 100uf 35v or 50 v cap. Examine your trace under it too. You may have to use the + lead of the cap as a trace to the 2 diodes to make up for the damaged trace.
I change C2 any time I work on a DE games, as the above will eventually happen.
