I have a Double Diamond Deluxe 3 reel machine (S2000+) and this started yesterday for no apparent reason. the slot sat idle for about 30 minutes and it just started displaying "Display passes self-test" over and over and will not boot.
I checked all of the connectors, and they seem good. I pulled the MPU and pressed on all the chips. The CR2354 battery reads 3.04 volts static with my meter, and there is no Varta battery.
The MPU lights are green, green, yellow, flashing yellow, yellow, yellow, green, flashing red.
Any help would be appreciated.
