Fluorescent light fixture problem

[woodpecker]

We bought a fluorescent light fixture at Home Depot for our kitchen
about a year ago. It uses 3 48" T8 bulbs. It stopped working (all
bulbs) a few days ago. I had one extra new bulb, so I tried replacing
each of the bulbs. That didn't work, so I replaced all of them. Still
not working. The only other symptom was that before it went out
completely, for a few days it occasionally quickly flashed off then
back on.

Any ideas as to what my next step should be?

Thanks!

Yes; replacing the ballast.

(Unless someone here knows some way of testing the ballast.)

But first, just make sure that power is actually reaching the fixture, and
that there are no intermittent connections internal to the fixture. *Then*
suspect the ballast ...

mostly pears.

the product.

And, if it's an electronic ballast that isn't potted, could be bad
solder joints on its PCB, though at this point with it being totally
dead, something may have blown.
