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.
Make sure power is off and then clean the fixture.
Clean exposed parts except for the interior portion of the bulb
sockets.
Clean the old fluorescent bulbs and let them dry.
Put old bulbs back in.
There is a good chance that it will work again.
Note: Over time, a thin film of grime accumulates on all exposed
surfaces and its conductivity varies by humidity. The grime
provides alternate electrical paths and essentially shorts out the
fluorescent fixture to the point where it fails to light.
The more conductive the grime(higher humidity) == less chance the
bulbs will light up.
