The Sony line-up of high-definition television sets have many different options in their settings menus to make the TVs more personalised for individual users. You can change brightness, contrast and many other settings while in the menu. If for any reason you need to reset the settings of a Sony XBR4 HDTV, you can do so using the remote control. If you do not have the remote, you can use the buttons on the TV itself to navigate the menu and reset the TV.
Press the "Menu" button on the HDTV and a list of main menu items will be displayed.
Press the "Channel Down" button on the HDTV until "Settings" are highlighted on the screen. Press the "Volume +" button to enter the settings.
Use the "Channel Down" button to navigate down on the next menu that is displayed. Stop when the "Set-up" option is highlighted.
Press the "Volume +" button to select "Set-up." Use the "Channel Down" button again to highlight the "Factory Settings" option.
Press the "Volume +" button on the TV to select the "Factory Settings" option. Press the "Volume +" button two more times to verify that you want to restore the default settings. The Sony XBR4 will turn off and turn back on. When it turns back on, the settings will be restored to the defaults.
