Self-diagnosis function

This monitor is equipped with a self-diagnosis function. If there is

a problem with your monitor or computer(s), the screen will go

blank and the ! (power) indicator will either light up green or

flash orange. If the ! (power) indicator is lit in orange, the

computer is in power saving mode. Try pressing any key on the

keyboard or moving the mouse.

If the

(power) indicator is green

Disconnect any plugs from the video input 1 and 2

connectors, or turn off the connected computer(s).

Press the

(power) button twice to turn the monitor

off and then on.

Hold the control button upward for 2 seconds

before the monitor enters power saving mode.

If all four color bars appear (white, red, green, blue), the monitor

is working properly. Reconnect the video input cables and check

the condition of your computer(s).

If the color bars do not appear, there is a potential monitor failure.

Inform your authorized Sony dealer of the monitor’s condition.

If the

(power) indicator is flashing orange

Press the

(power) button twice to turn the monitor off

and then on.

If the ! (power) indicator lights up green, the monitor is working

properly.

If the ! (power) indicator is still flashing, there is a potential

monitor failure. Count the number of seconds between orange

flashes of the ! (power) indicator and inform your authorized

Sony dealer of the monitor’s condition. Be sure to note the model

name and serial number of your monitor. Also note the make and

model of your computer and graphic board.
