    The DMD on my Safe Cracker is rolling. It's not the DMD (I've tried another). See video here:

    Any ideas? I'm guessing power supply, but any specific leads would be appreciated. Thanks,

    Joe

    Thank you very much. Need to source and buy these caps, so it might be a while, but I will report back.

    Sorry this took so long to follow up. I didn't have those caps on hand and none of my local buddies did either. Ordered from Mouser with a worst case delivery date of 2 weeks. 2 weeks comes, no mail from Mouser. I call them and they say the order must have got lost as tracking says post office never got the package. Anyway, they sent out a replacement and I received them today.

    Desoldered the two existing caps, soldered in the new caps and DMD is working great.

    THANK YOU BOTH SO MUCH FOR YOUR HELP.
