So... got an ICB.
When I turn the machine on, the Game Over star lights up, the lights on the playfield light up and strobe. The game makes NO sound (addressed below) and doesn't coin up.
I checked some voltages around the board/cabinet. The coindoor is getting it's voltage, I've got 5.02V on the +5 TP... but no 12V at the TP on the board. (hence no sound)
I pulled the power supply board and started looking at it. It's been worked on and BR1 and BR2 are different parts when, according to the manual, they should be the same. Looking at the solder, BR2 appears to be the original part, while BR1 is new (SK9075, RCA8508). I just want to go ahead and replace both of them with a known good replacement.
For other threads, the original parts are supposed to be (can't read mine) BR 251 25A 100V, where can I find replacements for these guys?
Also, is there anything else I should check for to get this back up and going? I've cleaned the edge connector and checked all fuses and fuse holders... they're all good. There really doesn't seem to be too much to this board, so I can't imagine there would be much that could go wrong with it.
