Top tip - our quick recommended solution
Before trying any of the troubleshooting steps below, we recommend that you remove the batteries from the remote control for approximately one minute. Then reinsert the batteries again according to the polarity (+ and -). If the issue continues, continue with the troubleshooting suggestions below.
Check the remote control operation after each step.
Check your TV
Make sure that the buttons on your TV work. If they do, skip the steps below and troubleshoot the remote control instead. If the TV buttons don't work, follow the instructions in this section.
- Check that the light (power/standby/activity light) on the TV 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 AC power adapter or power cord 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.
- If connections are complicated, make note of them, and then make sure that you can reconnect everything before you start disconnecting devices or cables.
- If the light flashes when a specific device is connected, the connected device may have a problem.
If the TV buttons still do not operate the TV, the TV may require repair.  Go to Product Repair.
Check your remote control
Check the remote control operation after completing each step.
- Press each button on the remote control twice to make sure none of the buttons are jammed.
- Reset the remote control.
- Open the battery compartment cover and remove the batteries.
- Press and hold the Power button for three seconds.

If the issue is caused by an external factor, such as network service, data broadcasting, or connected devices, it may be improved by a power reset.

- For other TV models, refer to the How do I power reset my LCD / LED or Projection TV article.
