Fixing a Tube Bulb and making it work.

When you turn on a fluorescent tube, if it does not light up and does not flicker, you should first make sure that the fixture is plugged in and that the fuse has not blown or that the circuit breaker has not been tripped. If this does not assist, try moving the tube gently back and forth and side to side in its sockets. If this does not help, try wiggling the tube gently in its sockets.

The ballast in a fluorescent light receives electricity, which causes it to send a spark through the tube (or bulb) that is filled with mercury vapor. This causes the phosphors that are coated on the interior of the tube to become activated, so producing light. The light won't function properly if even one of the components isn't working properly. When an issue is properly identified, the majority of its solutions are simple and straightforward. Keep in mind that you need to turn the power off first!

An old tube will flicker on and off just before it gives out; most of the time, all that has to be done to fix it is to replace it. Inadequate contact between the pins at the ends of a tube and the tube holders is another possible source of this issue. If the pins are deformed in any way, you may straighten them out using needle-nose pliers. Sandpaper of the appropriate grit should be used to clean the pins and socket contacts.

Gray bands at the ends of tubes are quite acceptable, but black bands at the ends of tubes are a sign that the tube needs to be changed. If there is just darkness at one end of the bulb, turn it end-for-end. If the tube is brand new and none of these solutions work, you may need to replace the starter or the ballast.

There are certain fixtures that are far less noisy than others, but the vast majority of fluorescent lights produce a faint hum. Turn off the power if the noise appears too loud or if you smell the burning smell of electrical components. There is a high probability that the ballast is either the incorrect kind, incorrectly placed, or faulty.

Both freshly manufactured tubes and cold bulbs have a propensity to flicker. If an older tube continues to flicker even after it has been given the opportunity to warm up (or after you have taken the time to warm up the room), spin it in the tube holders a few times. You might try cleaning the end pins of the tube. If it continues to be inoperable, you should replace it. If the ends of the tube are the only parts that light up, there is a problem with either the starter or the ballast. First the starter, then the ballast should be changed.
