Check the ballast

1. If the fluorescent lighting doesn’t come on, check to see if the ballast is the issue.
   
2. First, unplug the fluorescent lighting from the wall outlet.
3. Then, try switching the ballast. If the wattage of the ballast matches that of the fluorescent lighting, the fluorescent lighting should work after you switch the ballast.
4. If the wattage of the ballast doesn’t match the fluorescent lighting or you don’t want to swap out the ballast, try resetting the ballast.
5. To reset the ballast, plug the fluorescent lighting into the outlet.
6. Then, press the Test button.
   
7. If the fluorescent lighting is working after pressing the Test button, try resetting the ballast again.
8. If the issue persists, try replacing the ballast.
9. Look for burn marks
   Fluorescent lighting issues can result from burn marks on the ballast.
10. If the ballast is burnt, try replacing it with a new ballast.
    

Clean the connectors

1. Make sure the connector is clean and free of dust.
   
2. Use a vacuum cleaner with a brush attachment to clean it if needed.
3. Test the connector’s connection to a light
   Light bulbs should flicker if they are working.
4. If the light isn’t functioning, check the cord.
5. An exposed connection on the cord can cause the bulb not to light up.
6. You can also replace the bulb with another one.
7. Check the wiring
   Check the wiring connections, and look for loose wires.
8. If the wiring connections are correct, then replace the bulb.
   

Check the lamp

1. Many fluorescent lighting problems stem from the lamp. When a lamp fails, it will need to be changed. A lamp can fail when it burns out or breaks, or when it loses its ballast.
   
2. Check the lamp’s ballast. The ballast can be located either on the lamp itself or on the ceiling. If it is the latter, you will need to change the ceiling fixture.
3. A ballast failure is less likely, but if it is, it will result in the bulbs flickering, flickering with constant buzzing or flickering without buzzing, or flickering for only brief periods of time.
4. Check the light bulbs
   If the flickering occurs with constant buzzing, then the light bulbs may be damaged.
5. Turn off the socket and unplug the bulbs.
6. Remove the bulbs and inspect them. If the bulbs look damaged, they will need to be changed.
   
7. If the bulbs are not damaged, then check the socket.
8. Remove each bulb from the socket and inspect the sockets. If the sockets are damaged, they will need to be changed.
9. If the sockets look okay, then check the plug.
10. Remove the plug and inspect the wires.
11. If the wires are damaged, they will need to be changed.
    
12. If the wires are not damaged, then check the plug.
13. Remove the plug and inspect the socket.
14. If the socket is damaged or warped, it will need to be changed.
