Bad starter? These are basically the same situation, I think. When you
tap or move the bulb, it's sort of similar to making and breaking the
momentary contact switch used in some systems instead of a starter. Try
replacing the starter first & see if it clears up. If not, it's probably
the bulb. And if not the bulb, it has to be the ballast. :) If you have
a cheapo electronic ballast (lights-o-america shoplights & 24" "stick"
lights come to mind) then the whole thing will as a unit & you gotta
replace it (or rip out the guts & re-wire as instant-start T-8's).
