How to Troubleshoot TV Remote Control

Press the power button while pointing the remote control at your TV. Make sure the LED indicator on the TV blinks. If not, your remote does not have enough power remaining in the batteries. 

If you use Smart remote control, it may need to be paired to work properly again. Press the Return and Play/Pause buttons simultaneously for more than 3 seconds to display the pairing pop-up window. 

Remove any obstructions between your TV and your remote. If there are any objects between the remote and the receiver on the TV, infrared signals may be blocked. In addition, electronic equipment can disrupt the signal from your remote. If you have any electronics, such as lights, radios, or mobile devices around your TV, try moving them further away.

You can check the infrared signal by using any digital camera, including the one on your mobile device. Turn on the camera and point the front tip of the remote at the camera lens. Press and hold the power button on the remote while looking at the mobile device screen. You will see a light or flash coming from the remote. 

If you cannot see any light or flash coming from the remote and you have already replaced the batteries of the remote, it means that the remote has a problem.
