Hello, I need a little help / confirmation in my troubleshooting.. (Yes, I read the other treads, that's how I got this far ) I turned on TZ and it didn't report any errors, but after playing a few minutes and hit the Piano and the music didn't play, but the slot machine went off. I then hit the clock millions target which didn't register so I knew I had a problem. I turned it off the machine, checked the manual and I tracked everything that was dead to J206. (Piano, Clock, Lower left 5 Million, ect...)

I reseated J206 and restarted, again it booted clean but everything on J206 was still dead.

I go to the switch edge test and hold the clock millions target, it goes a little crazy and reports a ground fault...same result for everything else connected to J206. I turn the machine off again, pull the j206 connector off the board, I ground my black side of my multimeter then touch each metal tab inside the J206 connector with the RED side to see if I get continuity, I didn't. Did I do test this right?

If so, am I correct in then thinking U20 is toast? Is there a way to check U20?
Any other troubleshooting suggestions before I go that far?

I wasn't doing any maintenance before the errors started or replacing any lights.

Thanks for any guidance.

It looks like all the problem switches are on column 4, and will have a green/yellow wire on one of the terminals. I'd get a look at all of the switches on column 4 and see if there's any loose wiring or diodes on any of them, or if any part of those switches may be touching anything nearby.

I dont own a TZ but what the previous person said is spot on. If anything in that chain has lost a ground wire or a diode went bad that would do it. Unfortunately if a diode went bad it likely also took out the associated driver.
