Here’s how to do it:
- Unplug your TV from the power source after turning it off.
- Press the TV power button and hold for about 20 to 30 seconds.
- Release the TV power button and connect the TV to the power source.
- Switch it to a different device if you are trying to view an image from another device, such as a cable box. If this doesn’t work, access the settings menu on the television.
