I have a Bally Black and White, i took the top marquee glass out and set it on top of the open door( wire's were connected so i could not set off to the side) to change bulb and starter and i bumped it and it touch one of the reals and now i have 7.2 erreor showing where the credits should be. I tryed the reset button, and also turning it off and waiting a few min, still no go. Any suggestions on how to clear it? Thanks Darrell

Working on a Bally slot machine for a co-worker. I THINK it's a 5000 plus, but not 100% sure. Looking for a manual so I can get started troubleshooting.
Brought it home last night, and upon turning it on, I could see it was stuck in jackpot mode. No reset key, so I opened the cabinet and pushed the switch manually. Ran through setups, and it needed a reset. Found a video on YouTube showing me how to clear the settings and do a reset by powering off the machine, unplugging the top pcb, powering on, and waiting until I see 'CL' in the display.
That brought the machine to somewhat working status. I could coin it up and pull the handle, and the reels would spin. I played it until it won a small payout, and then it threw an error - 31 - which means hopper empty. So I filled the hopper, made sure the pressure switch was engaged. Turned off the machine, cleared it again, turned it back on. Played some more. Got a payout. No hopper movement at all. Error - hopper jam.
At this point, I've never seen the hopper motor move at all, not once.
No sound either. Tried adjusting what I believed to be the sound pot. Nothing. Tried a new speaker. Nothing.
I suspect a flaky power supply at this point.
This morning, on a cold fresh power on, I get no display on the LED. Owner told me that sometimes 'it takes a while' to get things going on the machine. Classic bad caps syndrome. I think I may need a new power supply.
Here's some pics I took. Can anyone confirm the model I have? And a link to a manual?
