Sony CPD-101VS - Manual (Page 15)

Damper wire
Using a white background, a very thin horizontal line on the screen may
be visible as shovm below. This line is the damper wire.
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 wire is attached to the Aperture Grille to prevent vibration
of the Aperture Grille wire so that the screen image is constantly stable.
