Vintage Synth Repair

Hi- I just got a hand me down Kurzweil 1000 PX (1989?) from my older 
brother. He owns a recording studio and thus takes very good care of 
his gear, but this one for some reason does not work. He had it 
sitting on a shelf for 8 years unplugged, so I know an electrical 
spike didn't short it out. When I turn it on, the screen lights up 
green, but no characters are displayed. I have the manual, and did 
what it told me (soft/hard reset) and that did nothing. I opened it 
up, and basically I figure the main board is not getting any power- 
the LCD backlight is powered right off the internal transformer. Any 
help or the name of a place in/near chicago that would repair such an 
instrument is very much appreciated.
