If you own a Sharp Aquos LC-52D64U LCD television, you may have had some issues during its operational lifetime. Calling technical support is often the wisest option, but sometimes a simple factory reset is all that's needed to restore your television to perfect working order. There are two methods to facilitate a factory reset: on-screen and using the hardware directly.

On-Screen Menu Reset

Step 1

Start up your television and press the "Menu" button on your remote control.

Step 2

Navigate through the menu options with the left and right arrow keys until you find the "Setup" sub-menu.

Step 3

Select "Reset" and press the "Enter" button. If you've set an access code--referred to as a "Secret Number"--for parental controls, enter it with the number pad on the remote control and press "Enter" again.

Step 4

Highlight "Yes" using the left or right arrow key and press "Enter."

Step 5

Select "Yes" again when prompted that the television will restart and press "Enter." The TV will then display "Now Initializing" and the power will shut off. The television will automatically turn back on, restored to factory defaults.

Hard Reset

Step 1

Unplug the television.

Step 2

Press and hold the "Channel Down" and "Input" buttons on the panel.

Step 3

Plug the television back in while holding down these buttons. You may need the assistance of another person to accomplish this step.

Step 4

Keep holding the buttons until the television powers back on. If it doesn't work, unplug the television and try again--sometimes this process doesn't work on the first try.

Step 5

Use the remote to navigate the "Service Mode" menu and select "Factory Reset" from the menu. Click "Enter" and the television will begin initializing and shut down. It will then power back on, set to factory defaults.
