7 TROUBLESHOOTING
• These are dampening wires. Dampening wires are
used to support the CRT’s aperture grille, and are
visible as thin dark lines across the screen. All
EIZO aperture-grille type CRTs include two such
horizontal wires.
The aperture grille itself is a grid of taut metal
filaments that spans the entire screen from top to
bottom.
• The aperture grille may be misaligned. Shock or
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 able to solved by:
• degaussing the screen, or
• 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 misaligned area of the grille,
returning it to proper alignment.
6) Two horizontal hairlines are
visible on the screen.
7) Faint black vertical lines are
visible on the screen.
