Try the pad on another cable/port. If it works, the problem is either the cable or the DM10 port.- TRIED IT, PROBLEM STILL EXISTS
Check the cable on the offending port. Try another pad on that cable, so you're sure the cable is good.- TESTED, CABLE IS GOOD
Open it back up and test the piezo by a very light touch on it, while plugged into your module, if nothing, then check the solder joints on the piezo... both ends of the wires.- IT PLAYS WHEN I TAP THE PLATE, BUT VERY LITTLE SOUND WHEN COMPLETELY ASSEMBLED. PLAYED FINE BEFORE MOD. I DID THE 8" NO DIFFERENT THAN THE 10/12"
