Quoted from Bam_Man:Turns out F4 was blown as well! Got a thunk and it's up and running. Now I just have to figure out why the lower and upper pop bumpers aren't working and the lower pf up kicker still isn't firing consistently. Basement lights (pointing down from main pf) don't turn on either. There's always something!
On these games, the pop bumpers each have a small, usually white-ish, board underneath. Find one of the boards associated with one of the working pop bumpers. Then with the power off, take the board from the working pop bumper and plug it in where one of the non working pop bumper's board. Fire er up and see if the one that wasn't working is working now. If it is, then you know that its something on that board. Most people just replace those with new ones because they aren't that expensive but you can definitely fix the old ones. The basement lights are a very special bulb even though they look like all the rest. Its entirely possible that they are all burnt out, take them out and double check by looking at the filament. They are #313 bulbs.
