Okay. Board fired up fine last year. Put it away for safe keeping and now it powers up, shows all IC's as 'OK' and then goes to black after a min or so and stays there.

Any ideas what to check? I noticed this IC which I think is the sound IC. Some pins don't look like they were soldered properly. Not sure if that could cause this problem though or if would just cause the sound to be messed up.

Open to any idea here.... 68000 is soldered on and I don't feel like ripping it off to toss on the Fluke.
 
I see nothing wrong with those pins, they don't appear to actually be connected to anything.

As for your issue, doubt it's the CPU itself if it's booting and running through power-up tests, but it sure could be low +5v once the actually game itself starts up.
 
If someone replaced that sound hybrid it could be that those pins aren't soldered properly. Those look suspiciously like ground pins that got ripped off when the module was desoldered from another board.

As for the game being dark... I've seen games where the module being physically damaged (cracked in 2) would have it booting up but failing the sound checks then rebooting... lather, rinse, and repeat until the game is powered off.

You say it's passing self tests so I'd say the ROMs and RAMs are OK. That leaves custom chips and traces to check. Look for bent pins on the customs that are shorting then check for gouged traces. Those Konami boards are TERRIBLY easy to gouge traces on.

After that, I'd swap the CPU out.

Thanks I'll take a look. I doubt it's the CPU cuz if it can run RAM/ROM self checks then it's prob okay. Unless that's the Z80's job.. I see one on there as well. And it doesn't show up on the schematics.

Incomplete schematics... just great.
