I have an issue with SST. It was running normally and suddenly it started to reset itself. After I turned it off and on again, it wouldn't boot up anymore (only GI lights are on, nothing on the DMD and no sound).
The led lights on the MPU board are not turning on at all anymore. The led lights on the power board however are on except the L2 (5v) and L204. I left the pinball off for more than a week and turned it on again. It started to work again and started to reset after awhile (2-5 minutes). After turning off, it didn't boot up anymore The boards have been serviced and should be working but I am still not able to boot it up. Does someone maybe have a tip where I could start looking for faults? Thanks for your help!
