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.
