I have no idea where to put this (lack of a drum forum) so i'm sorry if there is already somewhere.

On my Yamaha DTXplorer one of the cymbal pads (PCY65) has randomly stopped working. The 1/4" Jack cable is fine but the actual pad doesn't pick up any motion.

Heres some pictures to show the circuitry inside if that helps:

Any help is appreciated!
The pads themselves aren't that much, even 3-zone chokable cymbal triggers or whatever. Buy a new one. What probably happened is the piezo shit the bed. You could try to replace that, because those are only like $3.50, but it might be more complicated than your average pad if its one of those fancy cymbal pads.
