Troubleshooting

Before contacting technical support, refer to this section.

If thin lines appear on your screen (damper wires)

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.

1The frequencies of the current input signal

If the monitor recognizes the frequencies of the current input signal, the horizontal and vertical frequencies are displayed.

2The input signal conditionNO INPUT SINGAL

This indicates that no signal is input.

1The frequencies of the current input signal

If the monitor recognizes the frequencies of the current input signal, the horizontal and vertical frequencies are displayed.

2The input signal condition

OUT OF SCAN RANGE

This indicates that the input signal is not supported by the monitor’s specifications.

3The remedies

CHANGE SIGNAL TIMING appears on the screen. If you are replacing an old monitor with this monitor, reconnect the old monitor. Then adjust the computer’s graphic board so that the horizontal frequency is between 30 - 109 kHz, and the vertical frequency is between 48 - 160 Hz.
