Hi,

I picked up this pin years ago (had it shipped). It worked for probably a day and a half before failing, and I'm just now getting around to trying to fix it.

The current state on boot is that there is no sound (the speakers pop, but that's it), the DMD has almost all pixels on (though it flashes as I assume the image is updated), and the flippers do not actuate (though the buttons do register). I obviously can't access the test menu, given the DMD issue.

I don't know whether any of the issues are related. My best guess for the DMD is that the SRAM is bad, but I'd be interested to hear other opinions before I order a replacement part. I'm lost on the flippers and the sound. Any suggestions for debugging would be greatly appreciated.

Thanks in advance!
