What is an IR sensor?

IR sensor is short for infrared sensor, and the sole purpose of the IR sensor is to receive the signal from your remote control and send it to the main board as an electronic signal.

Which symptoms does an IR sensor fix in a TV?

•  If your TV does not respond to any remote control functions (and you’ve already ruled out any potential issues with your remote), then your IR sensor is likely 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 an IR sensor?

It's easy! Once you match the part number on your IR sensor 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.
