I recently traded for a nice Monopoly and had this issue come up three times over the course of 50 games or so. I THINK it happened right after hearing "Lock is lit" each time. It's very intermittent but it seemed software related due to nothing physically happening.

DMD goes off, music loops then eventually stops and the lights are stuck in a flickering loop. Anyone else experience this and know the fix?

Thanks,

Rob

what code are you using the lastest one had a crash problem and was stopped by stern go back to the previous one . 3.20 is bad go back to 3.03 , had very same problem and went to other code never had problem again

If you think it is software related, you can factory reset it to get any of the little gremlins out. If it still happens after that, I would start checking voltages at the CPU to see if your 5 volt is moving around at all.

Luch is right, the last code version had a crash bug in it. Go to "last version -1".

Weird because it's on 3.03 right now. I'll try a reset first then reseat the board connectors.

if no luck call Chaz at stern tech , he will help you , also try reseating the connectors under the play field along the wiring harness on the box floor

Check that. I'm on 3.20 i.e. The bad ROM. Need 3.03. Sent email to Stern. Anyone have a recommendation where to get one and an instructional video so I don't damage removal/installation?

replace all the bridge rectifiers.

Bridge rectifiers on Stern machines will some or all of the following:

- weak flippers
- brown outs / reboots and code freezing
- blown fuses
- sound issues

This is your problem.... The 3.20 code has a bug, the dice roll is always the same and that will make it land on unawardable spaces on the boards, which crashes the machine into the exact symptoms you describe.

Simply turn off machine, remove old rom chip, noting the notch location, and insert new chip with notch in same location, getting all pins in the socket. It's not that hard, you just need to be careful to gt the chip in the socket correct, and to get the notch right (NOT THE LABEL) on the chip.

John Wart, Jr. is probably your best bet to get a ROM if you need one.

All done. Got a new ROM from John Wart, Jr. and installed it today. Works great. Thanks everyone.

Thank goodness you didn't replace all the bridge rectifiers...
