only 1 of 2 fluorescent tubes in fixture lights up

I have a small fluorescent fixture in one section of the basement. It is about 2 years old and uses (2) 20 inch long tubes. About a week ago only one of the tubes lit so I changed the tube and no luck, and also switched the unlit tube to the "good" side and it works fine.

Anyone have any experience with this? I checked the wiring from the ballast to the sockets and all are connected. I want to check with my digital VOM but I don't know what kind of voltage AC or DC and the amount I should be reading. Thanks for any info

It could be a bad ballast. To check for certain I install two new bulbs. Unfortunately these days it's about the same price to replace the fixture as it is to get a new ballast.

Yes I've been there & done that more than a few years ago with a 4 foot fluorescent fixture it was cheaper to buy a whole new unit than a replacement ballast.
This rectangular fixture is semi-recessed into the ceiling and there is enough room that I'm considering removing the entire guts of this fluorescent and installed a double screw-in light bulb socket and use CFLs or regular bulbs.
