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.

Fast shipment. Part fit but didn't resolve the issue -- perhaps something else is wrong.

Q: Hi, is there a way I can verify this part has failed and not the screen? My screen flickers in pulses showing horizontal lines and a double image across the whole screen as if the timing were off, but goes away when it warms up. Unplugging one side blacks half of the screen, but it stops flickering on that half, and disconnecting the other side causes the opposite but that side flickers.

A: Sorry to hear that's the case! Unfortunately we don't offer a tech support service ourselves. We'd recommend heading to either Fixya.com or Badcaps.net for guidance on troubleshooting the issue if a local repair shop isn't an option.

We recommend matching the part number on your original part with the part number listed on this page to ensure compatibility.

While matching your model number is a great start, many models use variations of each part and they're not always interchangeable.

We include brief instructions in red text on some listings (also displayed below without the red font). Please look for these instructions to confirm any important info that you'll need to identify on your original part. Additionally, we highlight the part number in our photos.

Please don't hesitate to contact us with any questions. We're here to help!
