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, 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 or moving the mouse.
x If the 1 (power) indicator is green
1 Disconnect the video input cable or turn off the
connected computer.
2 Press the 1 (power) button twice to turn the monitor
off and then on.
3 Move the joystick , for 2 seconds.
If all 4 color bars appear (white, red, green, blue), the monitor is
working properly. Reconnect the video input cables. Adjust the
brightness and contrast, and check the monitor. If the fault still
exists, check 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.
x If the 1 (power) indicator is flashing orange
Turn the monitor OFF and then ON.
If the 1 (power) indicator lights up green, the monitor is working
properly.
If the 1 (power) indicator is still flashing, there is a potential
monitor failure. Count the number of seconds between orange
flashes of the 1 (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.
