None of the solenoids fire and a game will not start. The board shows corrosion and heat damage around a load resistor and the fuse clips.
No solenoids and no game start: corroded power board connector
Cause: A badly corroded connector on the board; the load resistor itself was not the fault.
Checks
- Check the board's test point voltages.
- Inspect the connector pins, fuse clips and nearby parts for corrosion and heat marks.
Fix
- Repin the corroded connector (both the header and the plug), replace damaged fuse clips, and repair or replace the board if traces are damaged.
The solenoid supply on this board is high enough to hurt; work with the game unplugged.
