    I would guess at he actual connection between the bulb and the end cap.. I have the same problem. Did you try to just twist the bulbs around and see if they start up again?.. when last did you clean them?

    Or it could be that one of your bulbs are on its way out.My Lighting unit was doing something similar and eventually didnt come on at all until after i changed one of my bulbs.

    When you say power supply, are you talking about the ballast ? If it's the ballast, either your cables are not connected correctly and you hearing the arcing, or the ballast is shot .

    I had a similar problem, mine stayed on for 5 seconds and then switched off....

    the problem on my unit was that the wires were not "shoved" deep enough into the ballast ... they were connected, just not properly!
