Fluorescent light how to troubleshoot, fault find and repair (electronic ballast)

Is your fluorescent light flickering, humming, or simply refusing to turn on? In this comprehensive troubleshooting guide, I show you how to diagnose and repair a fluorescent light fixture equipped with an electronic ballast. Unlike older magnetic ballasts, these electronic versions don't have a traditional starter, making the fault-finding process slightly different. I’ll walk you through safely isolating the circuit, removing the tube, and performing essential tests with a multimeter—including checking the electrodes and testing for short circuits within the ballast itself. You'll also learn visual cues to look for, such as "blackening" at the ends of the tube or a loss of vacuum in the phosphorous coating.
