Title: Pac-man cocktail plays blind - please help!
Post by: RossMachine on April 24, 2014, 04:28:06 pm
Hey guys!

So I recently picked up a Pac-man cocktail table in "unknown condition." After inspection, I added a powercord, got all new fuses, and turned it on. First, there was just the fan and a small pop from the speaker. Then I put in a quarter and heard the music! Awesome!

I took out the Nanao monitor only to find 2 small fuses in the chassis - 1 of which was broken (0.8A, 125v). After getting them from online, I installed one and turned the game on (knowing the monitor was getting good power from the isolation transformer). The monitor sounded like it was about to turn on when that "0.8a" fuse blew again. Why is it blowing this fuse?

I checked the HOT with a multimeter and it seems to be working fine. What can I do to help solve the issue from here?

Any help would be GREATLY appreciated! Thanks!

EDIT:
It's a Nanao but I'm not sure what kind exactly.

are you 100% sure the HOT is good?
It could also be the flyback, go7s are known for their flyback issues.

I set my multimeter on diode and tested the HOT pins. I got 495 for each.
The flyback has zero cracks and is not leaking and "appears" to be in good condition.

Nanao monitor? Ouch. That's not the original monitor, I'd say.

Personally, I'd shotgun that thing. Talk to Chad @ Arcadecup and get the parts you need. Caps, flyback, and HOT.

Or, send him the chassis to repair:

I had a Nanoa in my Turbo and he fixed it for me. That's one of the only monitors I never fixed myself. :)

Thanks for the responses! I appreciate any help.

I just want to have faith in that it could be just a small replacement part but I just can't figure out what.

Thanks for the link. Maybe I'll have to send it out.
Could I just get a universal replacement chassis online? Seems like it would be a better deal.
Any suggestions on where to get one?

I have no personal experience with this, but this guy has them. I know no one who has ordered from him.

Based on my experience, a blown fuse is usually hot or flyback. Ymmv.
