Damper wire

Using a white background, very thin horizontal lines on the screen are visible as
shown below. These lines are the damper wires.
The Trinitron tube has a vertically striped Aperture Grille inside. The Aperture
Grille allows more light to pass through to the screen giving the Trinitron CRT
more color and brightness.
The damper wires are attached to the Aperture Grille to prevent vibration of the
Aperture Grille wire so that the screen image is constantly stable.
The VOLUME/CONTRAST OSD disappears 3 seconds after you release the
buttons.
