Symptom
Action
The monitor has screen jitter, or
the screen image is wavy,
unreadable, rolling, or distorted.
1. If the monitor self-tests show that the monitor is working correctly, consider the
location of the monitor. Magnetic fields around other devices (such as

happens, turn off the monitor.
Attention:

discoloration.
Move the device and the monitor at least 305 mm (12 in.) apart, and turn on
the monitor.
Notes:
a. To prevent diskette drive read/write errors, make sure that the distance
between the monitor and any external diskette drive is at least 76 mm (3
in.).
