Help me fix fluorescent light fixture noise in a Williams Defender!
posted by plinth to Sports, Hobbies, & Recreation (4 answers total)
My Defender has massively bad screen hula when the florescent light in the header is on and none when it's disabled (either by pulling the tube or ballast). Picture here
I noted that the metal panel that it's mounted on was not connected to the cabinet ground strap, so I tried tying it in with alligator clips, but to no avail.
The machine is in fabulous condition with very few sketchy repairs and I'd like to keep it that way - installing a new light fixture is way down on my list of things I'd do to fix it.
Ideas? Would an old/failing ballast cause this? The light seems to come on pretty quickly at power up.
