Boss DD-5 problem

[TheBlackCrayon]

I'm very new at this pedal building and repairing thing and I need some help with my Boss DD-5. It just stopped working today, last night it was fine at band practice and today it won't come on, no led, no effects come through, nothing. Does anyone know of a pedal repair shop in LA or is there anyone here in LA that can help me get this fixed? Thanks guys.
