If it was the bulb, it would have had its end of life on/off cycle where it starts up, and goes out a few minutes later, and then restarts, many times. Nobody bumped into anything and knocked a cord loose?

Nope iv checked everything ,I only unpluged it and pluged it back in , the light wasn't on when I unpluged it.it's got to be the ballast cause it doesn't buzz or anything

[smileyface]

yeah, it must be. That sucks that it just stopped working. How old is it?
