well they can be easy to fix, but do it your self. compaq dwanted to charge me over $1000 to repair a screen on a laptop. i paid 100 for the parts and did it my self.
chances are the inverter electronics are bad. those are rather easy to fix. remove the inverter and find its modle number. try to order it from the maker. if that is not possible try to find one with similar power specs, connectors, ect.

the only hard thing about it is searching
