If your audio or screen settings need to be adjusted, you may want to reset your Sharp Aquos LC-52D64U to its factory default settings, restoring it to its original settings. In order to do this, you'll need to have your remote handy. You cannot reset the television using the control panel. You may also want to reset the Sharp's parental control password if you've forgotten it.
Resetting to the Factory Default
Turn your Sharp television on. Press the "Menu" button on your remote control. Press the "Right" arrow until you see "Setup."
Press the "Down" arrow until you see "Reset" displayed under the Setup menu. Press "Enter."
Type your secret four-digit code using the remote keypad. If you do not know it, you'll need to reset it by following the process in the section "Resetting the Parental Control Password." After you type in the code, "Reset to Factory Preset Values" will appear on the screen.
Press the "Right" arrow to select "Yes," then press "Enter." The screen will show "Now TV Will Restart." Press the "Right" arrow then press "Enter." Wait for the television to reset and revert to the factory default settings.
Resetting the Parental Control Password
Press "Menu" then press the "Right" arrow to select "Setup."
Press the "Down" arrow to select "Parental CTRL." Press and hold "Channel Up" and "Volume + " on the television control panel (not the remote) until the system requests you to set the parental control password.
Type in your new parental control password using the remote keypad.
