Monitor Specific Troubleshooting

Self-Test Feature Check (STFC)

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

If the LED indicator is green

Remove 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.
Press the button 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).

NOTE: The self-test pattern is stationary and will remain on. The power LED flashes green and amber.

If the color bars do not appear, there is a potential monitor failure. Inform your service representative of the monitor's condition.

Product Specific Symptoms

SPECIFIC SYMPTOMS	WHAT YOU SEE	POSSIBLE SOLUTIONS
Damper wire	Thin horizontal lines across the screen.	The lines you are experiencing on your screen are normal for the Trinitron monitor and are not a malfunction. These are shadows from the damper wires used to stabilize the aperture grille and are most noticeable when the screen's background is light (usually white). 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.
