Ok, i got the game as not working. I plug it in turn it on and the lights come on and the monitor comes on. It will not coin up and there is no sound.First check fuses, 2 blown 1 5amp on the brick and the one one the power supply board. Replaced both, and then started searching on here for same issues, and i found a post that helped out. I checked the power brick and yep one of the diodes was bad. So i went ahead and replaced all 4. Turned it back on and got the same issue. Got the book out and then started to check for voltages at the j4 and j5 plug on the power supply board.. All my plus 5 are at 3.8 and my 12 where at 10.8 I got the 10.8 back up to 12 by adj. the vr101 pot. but not able to do any thing with my 5 volts. i tried to adj. vr102 did not help. There is no burnt areas on the board, and checked for anything broke, torn, missing, ect.. still nothing.. Thanks ahead of time for any help or ideas.

Well, my MCR power supplies work mainly on luck, but here are a few things.
1. Take off that battery. If it has not already corroded the sockets on the connector next to it, it will.
2. It looks like someone has replaced the voltage adjustment pots. Interesting.
3. Bob Roberts sells a rebuild kit for these boards that basically replaces everything that might cause a problem on the board. If you don't want to spend a whole lot of time troubleshooting, here it is:

Edit: Forgot to say, that's a really nice looking game!

i would say like supertechnoboy said, rebuild the power supply. mine was the same way when i got it. you can also get the switcher kit as well, available through arcadeshop.com and whoever else.

very nice game, though. i wish my cabinet was as clean as yours is.
