Rescuing a K5

I would appreciate any recommendations regarding who could revive my K5 
synth.  With the years and various moves, its display no longer lights 
up and the keyboard generates no sound.  It clearly needs a complete 
diagnostic and perhaps major surgery to make it operational again.  I 
am not knowledgeable in electronics repair so I need a reputable party 
to take charge.  I live in the San Francisco Bay Area, so a local 
recommendation would be great, but I am willing to ship the K5 anywhere 
if it can be repaired.  Any advice and recommendations are gratefully 
appreciated!
Frank
