*“Sleep” and “deep sleep” are power saving modes defined by the Environmental Protection Agency.

DIAGNOSIS

This monitor is equipped with a self-diagnosis function. If there is a problem with your monitor or computer, the screen will go blank and the 1 (power) indicator will either light up green or flash orange. If the 1 (power) indicator is lit in orange, the computer is in power saving mode. Try pressing any key on the keyboard.

If all four color bars appear (white, red, green, blue), the monitor is working properly. Reconnect the video input cable and check the condition of your computer.

If the color bars do not appear, there is a potential monitor failure. Inform your authorized Sony dealer of the monitor’s condition.
