How to fix NAMCO Jumpin' Jackpot Toy with no lights?
- MMark BookerAug 1, 2025
If your NAMCO Toy has no lights, first check the AC input plug on the switching power supply and verify the power supply switch is ON. Then, check the DC output voltage at the 9-pin connector: RED to BLK should be 5+/-.15VDC, and ORG to BLK should be 12VDC -0/+1.8VDC. If the 12VDC is bad, check for output shorts by removing load connectors one at a time. If the loads are okay, or if the 5VDC is out of adjustment (4.95 to 5.05), adjust the power supply. If you suspect the main PCB rack is bad, verify by swapping with a known good unit. If service is required, contact your Distributor.
