It doesn't look broken. When you say "went out", do you mean just doesn't light up anymore with even a new bulb? Does the bulb flicker at all?

Most of the time all you need is a new ballast, that's the black box on the inside of the fixture. Take the ballast to home depot or lowes and try a new one. The purpose of the ballast is to blast the flourescent light with a burst of voltage to get the gas excited enough to light up.

If something else is amiss, maybe you can just buy a light fixture of the right length and cannibalize it to put the innards back into yours.
