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.

What is a key controller?

The buttons or keys on the front, side or back of your TV are attached to the key controller board. The purpose of this part is to send an electronic signal from the button you press to the main board.

Which symptoms does a key controller fix in a TV?

•  If you press a button on your TV and it doesn’t do anything, your key controller could be bad. This is assuming there aren’t any physical defects with the button(s) you’re pressing.
