Thin horizontal lines
on screen
Displays larger than 15 inches with tron-style CRTs typically
have two wires, each about one-quarter to one-third of the way
from the top and bottom of the display image. These supporting
wires, which are thinner than a human hair, stabilize the
aperture grill against shocks. The lines are common to all tron-
style displays and are not screen defects. The lines cannot be
adjusted out or eliminated by repairing or replacing modules in
the display.
