What is a main board?

The main board is basically the ā€œbrainsā€ of your TV and controls everything, from the audio to video streams. All of the user data and settings are also stored on the main board.

Which symptoms does a main board fix in a TV?

•  If your TV doesnā€™t turn on, it could be the main board. If your TV turns on but has no video and/or no audio, it could also be the main board.

•  If one HDMI input works but others donā€™t work, it could be the main board.

*These are helpful tips to get you started and donā€™t represent accurate diagnoses for every TV model and failure. If youā€™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 main board?

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