Before removing the processor board, check the following areas:
- Use output test 27 to verify the problem
- Check 24V, 5A fuse
- Check wires and connectors for defects
Note: Denomination must be set to a value other than 0. In credit mode, the number of credits accumulated must be less than maximum coin-in unless software permits programming level.
If that doesn’t work, try the following steps:
- Replace the processor board with a “known good” one
- If the processor board seems bad, check eBay for replacement or repair service
- If the processor board is good, then replace the motherboard
- To repair the motherboard, use this diagram to isolate the bad trace
- If the motherboard and processor board are good, then use this diagram to test for wire continuity
