Press the "Power" button on the front of the television or on the remote.
Locate the "Reset" button on the bottom left of the Sanyo remote that came with the television. If using a universal remote, the "Reset" button may be elsewhere on the device. If you do not see the "Reset" button proceed directly to Step 3; otherwise skip to Step 4.
Press the "Menu" button on the remote. Scroll through the on-screen menu until you see the option to "Reset all settings" or "Factory reset." Use the remote directional buttons to navigate to the "Reset" option. Press "Enter" or "OK" on the universal remote. Press "Enter" or "OK" again to confirm the "Reset."
Press the "Reset" button. An on-screen message appears. Press "Reset" once again to confirm and reset all settings to the factory settings.
