Have you checked with a meter to se if the plug that leads from the outside of the cabinet to the power supply is good? And any connections are not working properly?

Sorry, I'm late to the party.

Are you getting a neck glow on the monitor?

If you're getting power TO the power supply boards, check the voltage coming out. If you're getting nothing out, then you'll probably want to order a Bally/Midway MCR power supply rebuild kit from Bob Roberts (http://www.therealbobroberts.net) or a switching power supply adapter board from Wizzes Workshop or Arcade Shop (.coms)

It's actually a good thing the screen went blank, most of the time... the BIG faults are usually easy to find... it's the little ones like graphic issues and sound issues that suck with MCR boardsets.

If you were in the Nashville, Tennessee area I'd swing by and have a look at her for you.
