Before using the (COLOR RETURN)
feature in the
(COLOR) menu, the monitor must be in normal operation mode (green power indicator on) for at
least 30 minutes. If the monitor goes into power saving mode, you must return
the monitor to normal operation mode and wait for 30 minutes for the monitor
to be ready. You may need to adjust your computer's power saving settings
to keep the monitor in normal operation mode for the full 30 minutes. If the
monitor is not ready, the following message will appear.
Sometimes, no warning message appears, but the screen is blank, which could also indicate that the monitor is not synchronizing with the computer.

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. |
