What is a power supply board?

Your TV’s power supply board takes the AC voltage from your outlet and converts it to various DC voltages needed to power everything in your TV.

Which symptoms does a power supply board fix in a TV?

•  If your TV doesn’t turn on, it could be the power supply board.

•  If you see very dim video or no video on the screen, but you know your TV has power and is on, then the power supply could be bad.

•  If your TV turns on and then shuts off quickly, it could be your power supply board.

*These are helpful tips to get you started and don’t represent accurate diagnoses for every TV model and failure. If you’re unsure of your diagnosis, we recommend checking out our YouTube channel or reaching out to a local TV technician for assistance.

How easy is it to replace a power supply board?

It's easy! Once you match the part number on your power supply board with the part number listed on this page to confirm compatibility, you’ll just need a screwdriver and the ability to remove the back of your TV and replace the board.
