IBM 8841 - eServer xSeries 236, Руководство по установке

Страница: 63 / 100

Symptom Suggested action
The monitor has screen jitter, or
the screen image is wavy,
unreadable, rolling, or distorted.
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 transformers,
appliances, fluorescent lights, and other monitors) can cause screen jitter or wavy,
unreadable, rolling, or distorted screen images. If this happens, turn off the monitor.
Attention: Moving a color monitor while it is turned on might cause screen
discoloration.
Move the device and the monitor at least 300 mm (12 in.) apart, and turn on the
monitor.
Notes:
1. To prevent diskette drive read/write errors, make sure that the distance
between the monitor and diskette drives is at least 75 mm (3 in.).
2. Non-IBM monitor cables might cause unpredictable problems.
3. An enhanced monitor cable with additional shielding is available for the 9521
and 9527 monitors. For information about the enhanced monitor cable, contact
your IBM marketing representative or authorized reseller.
If the problem remains, call for service.
Wrong characters appear on the
