Fluorescent light fixture problem

    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!

    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 ...

  3. Yes; replacing the ballast.

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

    Made From Pears: Pretty good chance that the product is at least
    mostly pears.
    Made With Pears: Pretty good chance that pears will be detectable in
    the product.
    Contains Pears: One pear seed per multiple tons of product.

    (with apologies to Dorothy L. Sayers)
     
  4. 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.
