Before removing the processor board, check the following areas:
- Verify the problem by checking the input test in the self test mode
- Check to see if the button assembly is clean with no broken or missing parts
- If the other switches are nonfunctional, replace the Bet Max switch first
- Connect one meter lead to the normally open leg of the switch and connect the other meter lead to the chassis ground (B gnd), then measure for 8 to 10 VDC
- Activate the switch-the voltage should drop to zero volts
- Test for continuity from Bet One switch common to the normally closed leg of the Change switch
- If the switch measures open, then measure the next switch inward until a low resistance is measured
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.
