If I were you I would try the generic stuff: plug,cord, connections to the bulb, and if you have or can get a bulb the bulb. these are really just a special floursecent light so any electrican could find the trouble if it's just not lighting. If you can't do this stuff yourself i have two suggestions: First is call Midwest Photo Exchange and or Columbus Camera Group and see if they know anyone, secound call some local electricans and see if you could take it to one of them for them to look at and find the the problem and hopefully fix it .
