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.
