If you suspect a powe problem you can check with a DMM. The problems you're reporting sound like a logic problem. Logic runs on 5V where the ColorDMD draws its power from 12V. I think it's unlikely to be a power driver problem.

It's more likely that communication on the logic bus is failing due to a ribbon cable being connected improperly or the Whitestar DMD controller board not receiving power.

Can you post a few photos that show the cable connections in the backbox and to the Whitestar and ColorDMD display boards?

To move the display close to the speaker panel, it's necessary to trim the plastic at the top. This is described in the custom instructions for DE plastic speaker panels on the hardware support page.

The shape of the DE speaker panel makes installation more difficult for DE games than Stern or WPC.

For anyone having issues with sound dropouts or reboots, I took a quick look at the DE power driver board schematic.

The 12V bridge/cap at DB1 and C4 provide unregulated +12V which feeds (among other things) the ColorDMD and the +5V voltage regulator which drives the logic circuits.

+5V is generated from the regulator at IC1 and transistor at TR5.

If the bridge/cap above are not holding +12V properly, fast voltage changes at the input to the 5V regulator may not be tracked out and cause issues with 5V dropouts.

Please check the voltage at +12V. (An oscilloscope might be necessary to see if there are rapid voltage swings.)

If you suspect problems, consider replacing C4 and/or DB1 to see if it can resolve the issue.

COLORDMD ROM UPDATE!

The Tommy 3.2 color ROM update has been posted to our SUPPORT page and is now available for immediate download. The update adds support for Chad Hendrickson's unofficial 5.0 game code release that adds new features for Tommy as well as additional animation sequences. The new color ROM still continues to support the official 4.0 game release.

The new ROM is available for both LCD and LED displays.

Thanks very much to Frank Gigliotti for all the hard work to make this available for all to enjoy!
