Go to Video Setup, Display Options and then Screen Saver. from the manual:
"Screen Saver – To turn on/off the screen saver function. The screen saver is designed to
minimize burn-in concerns for plasma and CRT display devices. The available options are:
• On – After about 3 minutes of inactivity, the player will show an animated OPPO logo
moving on a black background. This allows most areas of the screen to rest and gives
all areas an equal opportunity to refresh.
• Off – The screen saver will not be activated. Use this option if your TV does not have a
burn-in issue.
• Energy Saver – Video output will be turned off after 3 minutes of inactivity. Many
projectors and LCD TVs will go into a standby or sleep mode and turn off their
projection lamp or LCD backlight lamp, thus saving energy and prolonging the lamp life.
When you press any button on the OPPO remote control or the player’s front panel, the
screen saver will be canceled and video output will be restored. If your TV is already in
standby or sleep mode, you may need to wake up the TV by pressing a button on its
remote or control panel. "
