TV power supply unit faults

Faults in the TV's power supply unit can be corrected or avoided in most cases with proper maintenance. Proper maintenance and preventive measures should be taken to ensure that the power supply operates efficiently.

Before troubleshooting any problems with your TV's power supply unit, it is important to make sure that all cables are connected correctly and that the power socket being used is properly earthed. Also, before attempting to troubleshoot any problems with the power supply unit, check that the TV's internal fuse has not blown.

In some cases, it may be necessary to replace components of the power supply to get it working properly again.
