ITEMS TO CHECK

LOCATION

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 levels after this procedure.

The 2 very faint thin lines across the screen are normal. They are caused by the aperture grille stabilization filaments(Damper Wires) which are required for all aperture grille CRTs’.
