Sony CPD-101VS - Manual (Page 40)

A fine horizontal line (wire) is visible
m This wire stabilizes the vertically striped Aperture Grille (page 16).
This Aperture Grille allows more light to pass through to the screen
giving the Trinitron CRT more color and brightness.
Hum is heard right after the power is turned on
m When the power is turned on, the Auto-degauss cycle is activated.
While the Auto-degauss cycle is activated, a hum may be heard. The
same hum is heard when the display is manually degaussed. This is
not a malfunction.
• If the problem persists, call your authorized Sony dealer from a

(1-888-476-6972).
