How do I reset the 52" TV to original settings. Screen is on Widescreen permanently

Could you please post exact model of your sharp tv. however i will give you this generic solution. In order to do this, you'll need to have your remote handy. You cannot reset the television using the control panel.
  • Turn your Sharp television on. Press the "Menu" button on your remote control. Press the "Right" arrow until you see "Setup."

  • 2

    Press the "Down" arrow until you see "Reset" displayed under the Setup menu. Press "Enter."

  • 3

    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.
