If thin lines appear on the screen

(damper wires)

These lines do not indicate a malfunction; they are a normal effect of the Trinitron picture tube with this monitor. These are shadows from the damper wires used to stabilize the aperture grille. The aperture grille is the essential element that makes a Trinitron picture tube unique by allowing more light to reach the screen, resulting in a brighter, more detailed picture.

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.

1 Disconnect any plugs from the video input 1 and 2 connectors, or turn off the connected computer(s).

2 Turn the monitor OFF and then ON.

3 Hold the control button upward for a few seconds before the monitor enters power saving mode.

If all 4 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.

xIf the ! (power) indicator is flashing orange

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 graphics board.
