If you landed on this page and made it this far, you're probably thinking that your T-Con board might be failing in your TV. Let's first review the T-Con board's purpose in a TV and common T-Con board symptoms.

What is a T-Con board in a TV?

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.

T-Con boards are made by the same manufacturer as the LCD screen (LG, Samsung, AUO, etc.). For example, you may have an LG TV, however the LCD screen and T-Con board could be from a different manufacturer.

Which symptoms does replacing your 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.
