What is a TV repair kit?

TV repair kits typically contain every board in your TV (excluding LED strips). If you’re unsure of your diagnosis, you can order this kit and replace all of the boards in your TV.

Which symptoms does a TV repair kit fix in a TV?

•  A TV repair kit can fix most symptoms in your TV, from no power to no video or audio to WiFi issues.

*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 TV repair kit?

It's easy! Once you match the part numbers on your boards with the part numbers 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 boards.

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!
