Top tip - our quick recommended solution

Before continuing to the various troubleshooting steps, we recommend that you remove the batteries from the remote control, then press and hold the Power button for three seconds. Wait a minute or so, then reinsert the batteries according to the polarity (+ and -). If the issue continues, continue with the troubleshooting suggestions provided.

Note: When your TV doesn't respond to your remote control commands, the issue could be related to your TV or the remote control. Steps are provided to troubleshoot both.

Check the applicable steps as needed.

Check for an issue with your TV

This section helps troubleshoot if there's an issue with the TV, not the remote control.

Check the operation of the available buttons (on/off, volume up/down, channel, etc.) on your TV. Press the buttons on the TV itself to verify that the TV will respond and is working properly. If your TV responds to the buttons on the TV but not the remote, continue to the steps to troubleshoot the remote control instead. If the TV buttons don't work, follow the instructions in this section.

Note: The available TV buttons and their positions may vary. Check the sides, back, front, and top of your TV.

Check that the TV's light (power/standby/activity light) is on.

Note: Depending on the model, the location and shape of the light vary. If the light is on or blinking in red, proceed to the next step.If the light isn't on, check the TV AC power cord (and power adapter where applicable) to make sure it isn't unplugged or loose. If there is no issue with the connection, proceed to the next step.

Note: A no-light condition isn't always an indicator of no power. If the light isn't on, check if the light comes on when pressing various buttons on the remote control. Some models are set by default to only light up when using the remote. It's also possible on some models for the user to select a light (Illumination LED) setting in Device Preferences to not come on at all. Remove external devices (external USB hard disk, devices connected with HDMI cable, etc.) and cables from the ports on the TV to confirm if a connected device may be causing the problem. Do not remove the TV power cable at this time.If connections are complicated, make note of them (maybe take a picture of your connections), and then make sure that you can reconnect everything before you start disconnecting devices or cables.Check if your TV operates without external devices connected, reconnecting external devices one at a time.If the light flashes when a specific device is connected, the connected device may have a problem. Perform a power reset of your TV. Temporary and intermittent issues are often resolved by performing a power reset. Unplug the power cord for your TV, wait about two minutes, and then plug it back in.

If the TV buttons still do not operate, the TV may require repair. Go to Product Repair.
