I have a sample TZ and I was playing a game today and everything was working great and then the color DMD died and the flippers died and I could hear what sounded like the trough kicker kicking over and over and I could smell something burning. I powered off and tried to find the source of the burning before turning it back on to test. I could not find the source. I was able to power back on by switching back to the original DMD and had the message. "Check Fuses F115 and F116 J112 and Opto 12V Supply" I replaced F116 (F115 was ok) and powered back up. Things seems better but I get the Check switch 73 - 75 - 76 - 81 - 83 (all Optos) I started testing the rest of the fuses and found that F501 on the audio board was blown. I replaced it and powered on and it blew again right away. Looking closer, I see there is damage to C28. (picture attached) Oddly, there is still sound, not sure how much because I stopped here.

Not sure where to go from here. Any help would be appreciated.

Thanks. I also have a working Bride of Pinbot Sound Board I could swap in. I am just afraid to fry that one too. I wonder if there is a chance that it is getting too much power from another source

Ok. I put the Bride of Pinbot sound board in without even changing the ROM chips. It powered up great, no blown fuses. Played a little with the sounds from BoP, went into switch test and all the switches were back. I put the TZ sound board back in with the blown fuse and burnt cap. Powered it on, went into switch test, everything checked out. Played a couple games and sound was working and as far as I can tell everything is working again, even with the bad sound board. Not sure how that is even possible.

Thanks Coyote. I will definitely recap that board and make sure it is stable before I play it again. I hope Great Plains has them all in stock. I know Marco has the others, but I didn't see the TANT caps.

I was able to get them all from Digikey and ordered them last night and they already shipped and should be here Tuesday. I bumped a couple up, but was afraid of the size thing too. Guess I should have went bigger. LOL

Thanks again for the advice.
