Follow the troubleshooting steps below to get your Fire TV remote control performing as it should:

1. Perform an IR test:
 

Using any digital camera, a smartphone or tablet with a built-in camera perform an IR test. Such device is capable of “seeing” a wider range of light wavelengths than the human eye and can therefore detect infra-red light.

• If using a smartphone with a front-facing camera, be sure to set the camera to “selfie” mode as if you were taking a self-portrait (you should see yourself in the camera).
• Point the remote control towards the camera then press and hold the “Power” button on the remote. 
• If the IR light emits, that means the remote has power.
• If there is no IR light, please continue through these troubleshooting steps.

2. Additional Steps

• Verify that it's the remote that came with the TV and it has a TCL Logo.
• Aim the remote directly at the TV.  Make sure you are pointing the remote directly at the TV. 
• Try reinstalling the batteries.  If the remote is still unresponsive or intermittently responding, it is possible the batteries were installed incorrectly.  Try removing the batteries from the remote and re-inserting them.  

• Insert batteries in the correct polarity as indicated in the battery compartment. If there is no improvement after reseating the batteries, try replacing them.
• Reset the remote using the following steps below:

When the LED indicator blinks blue, your remote is paired successfully. If it's not paired, press the Home button for 10 seconds.

3. Pair the remote:

The Fire TV remote should automatically pair with the TCL TV. If it does not, follow the steps below.

• Move your remote closer to your device. (Must be within 10ft/3m).
• Press the Homebutton until "Pressto start" appears on-screen (about 10 seconds).
