LUMIX DMC-FZ15 won't powerup - church group needs help

[trpreacher]

A helpful teen tried charging our youth group's FZ15 with the charger from another gadget - and I'm assuming either tripped something or burnt something so that the camera won't poweron anymore. Can anyone suggest anything other than sending it back to panasonic for a 165.00 minimum repair. I bought a new battery, charged it and no luck. Is there some sort of reset for this camera. Any help would be appreciated as it was donated, is out of warranty, and was heavily used.

Thanks
