Been restoring a Xenon machine. Here's all that I've done so far:
Rebuilt -54 board along with new male & female connectors and pins.
Replaced all the ceremic caps and diodes on the playfield switches (most were cut)
Replaces some bad / locked on coils
Brand new Alltek MPU board
Brand new Rottendog solenoid driver board
Brand new Rottendog LED displays
Game boots up fine and starts out playing good. Maybe 5 minutes into my first game, the unit lets a quick, sizzle type sound out of the speakers and basically powers itself down. Reboot and it's good to go for a while then does the same thing again.
I've read about similar items happening due to bad caps on the sound board(s). Is this my next logical step in troubleshooting it? Disconnect the sound board and see if the same thing happens?
