The jester bell lamps, Draw Poker lamp and a few other inserts light normally during play until Draw Poker is collected; then they all stay off for a long time. Jumpering the lamps lights them, and relays and the lamp board had already been swapped.
A group of lamps goes dark after Draw Poker and stays off: failed transistor Q58
Cause: A failed driver transistor, Q58, for that group of lamps.
Checks
- Use the lamp matrix chart to find what the dead lamps have in common.
- Look for a working lamp on the same string to rule out a broken wire.
Fix
- Replace transistor Q58.
