During the operation of fluorescent lamps, malfunctions may occur in the switching circuit for a variety of reasons. In some cases, it is not possible to eliminate the breakdown, while in others the problem is solved by identifying and eliminating faults.
Instructions
Step 1
Reposition the fluorescent lamp so that the normally glowing and faulty ends are reversed. If in this case there is no glow, then the lamp is recognized as defective and must be replaced with a new one.
Step 2
Check the wiring diagram and lamp socket if replacing it did not correct the lack of glow. Eliminate the cause of the short circuit or replace the cartridge if necessary.
Step 3
Look for a malfunction in the starter, wiring, or socket if the fluorescent tube ends with a glow but does not fully ignite. If, after turning off the starter, the glow disappears, this means that the cause of the malfunction was in it. If the glow remains at the ends of the lamp, check the starter socket and wiring for a short. Eliminate faults or replace parts.
Step 4
Replace the fluorescent lamp if an orange glow appears and disappears at its ends when switched on, but the device itself does not light up. This means that air has entered the lamp. There is no way to fix this problem.
Step 5
Check the operating and starting current values if the fluorescent lamp lights up but over time there is a strong darkening at the ends. This means that the fault is in the choke, which receives operating and starting current that does not correspond to the required volt-ampere characteristics. If the check did not reveal any errors, then the breakdown should be looked for in the poor quality of the cathodes.
Step 6
Measure the voltage drop across the lamp if it periodically turns on and off. This signals that the voltage drop across the lamp does not match the voltage, it is necessary to ignite a discharge in the starter. If it turns out to be more, then it is necessary to replace the faulty lamp. If less, then the cause of the breakdown is in the starter.
Step 7
Replace the choke in the design of the fluorescent lamp if, when turned on, the coils are burned out, since insulation may be broken in its winding.
