PROBLEM

ITEMS TO CHECK LOCATION

•

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 levels after this procedure.

Two fine horizontal

lines are visible on

the screen.

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’.

A buzzing sound

when power on.

A brief vibration or hum sound that is heard just after power

up is normal. This is caused by the automatic degaussing

function. This sound will be heard each time the monitor is

powered up from a cold start and each time the manual

degauss button is used.
