Sony HMD-A240 manual Specifications, If thin lines appear on the screen, Self-diagnosis function

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 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.

xIf 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.

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.
