Before contacting technical support, refer to this section.

The visible lines on your screen especially when the background 
screen color is light (usually white), are normal for the Trinitron 
monitor. This is not a malfunction. 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.

If there is something wrong with the input signal, one of the 
following messages appears on the screen.

This indicates that no signal is input from the selected connector.
