I have a fixture in my kitchen that has (4) 40W bulbs. Last week the
outer bulbs grew dim and finally the fixture quit lighting up at all. I
replaced the bulbs today...and the outer bulbs are not working. I've
tried replacing all 4 bulbs, still the outers aren't work (even put a
known good bulb in each of the outer locations). Is this the sign of a
bad ballast or another issue? All connections are nice and tight.
