When experiencing problems with your LCD TV, including the television powering off unexpectedly, not receiving signals from your cable box or VCR, or functions not working properly, you don't have to ignore the problems or take the TV to a repair shop. LCD TVs are equipped with a reset function that returns the television to its original settings. Once your LCD TV is reset, test the television by accessing the various functions using the television's remote control or front panel buttons.
Turn on your LCD TV, if it is off. Press the "Menu" button on the TV's remote control or on the front panel of the television.

Press the "OK" or "Enter" key to select the option. Your LCD TV will now reset.
Press the "Channel Up/Down" buttons on your TV's remote control or front panel to test your LCD TV once the resetting process is complete.
