I was recently given a Wild Fyre by a friend due to a death in their family (and lack of desire to repair the machine by other family members). I've gone through the MPU-100 repair document (at TechDose) and been fairly successful in resurrecting the machine so far. The issue I'm having is the displays (LCDs?) for score and similar info don't light up at all - not even a flicker.
- I get 6 flashes of the diagnostic LED, then it stays lit at a low level. After the 6th flash, there is a continuous 'noise' - almost an electronic hum - that is constant. However, I can run through diagnostics using the self-test button and everything I can test without the displays seem to work fine (e.g., sound test works, lights blink properly, solenoids all fire appropriately, etc.)
- No fuses appear to be blown.
- The battery is removed. I have not replaced it with a battery pack as of yet.
Any thoughts or direction people may have would be a HUGE help. There are one or two minor items that also need to be fixed (e.g., one of the kickers doesn't activate when the ball is in the hole, but activates during solenoid testing) - but if I can get the above fixed it really seems to just have 'minor' issues.
