Blackout issues

[MothraRZ]

Had both the MPU and the Driver board serviced in the last few years. It will start a game but then I lose some of the scoring lights and all GI. What is the chance a new rottendog power supply will fix my issues?? I am desperate to get this working by my Christmas party. is it worth a shot?

Most likely it is connectors. It almost always is.

like he said connectors, the GI isnt controlled so check/reseat/inspect all your connections at the power supply board & check for broken solder on the pins

Tried the new PS board.......figured the upgrade is worth the money in the long run anyways. Still have the same issues. No GI, no backbox, and some of the scoring lights on the playfield do not work. In attract mode only the 20 in the middle of the white lights light. the rest seem to work. Something is funky when you start a game it like locks up some parts of it.

not looking at the manual but in the lamp test what is lit? do you have the manual & schematics? have you checked the fuses & fuse holders? have you pulled and reseated the gi wiring connections? are all the boards screwed with metal screws to the grounding plate in the backbox? are you getting a steady 5v on the mpu? good ground continuance is needed between all boards
