I'm hoping someone here can help!!! I bought a non booting F2K. Got 2 flashes, tested the 2 5101's one was bad so I replaced it. I get the flicker and seven flashes but it won't boot nor will the displays light up. Prior to working on the mpu I replaced the rectifier board because voltages were wrong when I got it. All the voltages test ok now. I also put in a tested working rebuilt SDB and re pinned all the display connectors. Can anyone point me in the right direction to try and get the game to go into attract mode and the displays come on after the seventh flash?

I have 3 balls in it and have disconnected the sound board and still won't come up!
The trough switch has been flakey and was making it search for balls but I have adjusted it, still going to replace switch but not searching for balls anymore.

I'm thinking I may put a jumper across that switch just to check but I don't think that's it since it is no longer searching for balls?
