If anyone figures this out I'll be amazed!

Picked up a funhouse a few years ago that sat in a home most of it's life. Of course owner never changed batteries. Cleaned up acid on the board best I could, game was funtional with the occasional coindoor buttons acting goofy.

Finally had board professionaly fixed socketed and nvramed. And put in new rottendog driver.

Turn on game for the first time and can't get to boot. If I disconnect display cable from mpu game boots. I can actually play full game with no display. If I try to plug ribbon cable back to mpu game shuts down, but if I pull cable off it boots back up.

I had extra display with boards on it and same thing. New ribbon cable, same.

I'm guessing it's something on MPU? I've had my share of problems with new rottendog drives too.

Any help is much appreciated.

Thank you in advance!

Yes Deja Vu. I'm an idiot!
Zaza, if you were closer I'd at least buy ya a drink..............and try to convince you that I have a couple of brain cells.

Thanks once again my friend. If you see I have any parts or games for sale that you're interested in I owe you huge discount.

Thanks all that helped. Pinside is the best!

Ya, I showed my wife all this and it just confirmed what she knew.......you can tell me more than once and I still don't learn.

You're right about not causing harm. I'm lucky.

Thanks again!
