Thin horizontal lines appear on your screen

Thin horizontal lines are normal for an aperture grille CRT 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).

Black vertical lines are visible on the screen

Thin vertical black lines on one or both sides of the screen. This minor condition is caused by grille element overlap which can occur during shipping.

Position an open white window over the affected area of the screen and maximize the brightness and contrast controls. This will cause localized heating of the overlap which will clear in a few minutes. Be sure to readjust the brightness and contrast controls back to the normal viewing level after this procedure.
