vibration during transport may, in some cases, cause the

 

aperture grille to fall out of alignment. The problem will

 

appear as one or more faint black lines across the screen.

 

If this problem occurs, it may be solved by:

 

1. Degaussing the screen.

 

2. Lightly tapping (do not hit) the side of the monitor.

 

If neither of these methods works, try executing the

 

following procedure.

 

1. Display a bright white field over the area where the

 

black line(s) appear, with a black field over the

 

unaffected areas. (Do this by opening a bright-white

 

window on top of a black desktop or wallpaper

 

background. Position the window so that it just covers

 

the area of misalignment.)

 

2. Set brightness and contrast to maximum values, and

 

keep the display ON until the problem is corrected.

 

Try tapping the side of the display lightly to help

 

expedite realignment. The white field will heat up the
