What is a T-con board?

A T-con board — short for “timing control board” or “timing controller” — is found in LED and LCD TVs. This board converts the video signal from the main board and sends it directly to the screen to display the signal in the correct order and at the correct spot on the screen.

Which symptoms does a T-con board fix in a TV?

•  If your TV has no video, then the T-con board could be bad.

•  If your TV only has video on a fourth or half of the screen, then the T-con board could be bad.

*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 T-con board?

It's easy! Once you match the part number on your T-con 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.
