Only one side of my fluorescent light works. If just one of the fluorescent tubes does not light with a fixture with 2 or 4 bulbs obviously it could be a burned out bulb before doing anything that involves replacing. Most modern fluorescent fixtures do not use starters so you might not find one if your fixture is less than 15 to 20 years old.

Older fluorescent light fixtures that flicker or only light up part way may just need a new starter which is a less expensive repair than a bulb. To remove press on the clips or detach the screws holding the diffuser. One clue that your ballast is the reason for a non working fluorescent light is the light bulbs struggle to turn on.

If the fluorescent tube is flickering or dead when you turn the light switch on remove the light diffuser if any. The light diffuser is the plastic piece that covers the light fixture.
