Table 6. Troubleshooting charts (continued)
Symptom
Suggested action
The screen is wavy, unreadable,
rolling, distorted, or has screen
jitter.
If the monitor self-tests show the monitor is working properly, 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.
(Moving a color monitor while it is turned on might cause screen discoloration.)
Then move the device and the monitor at least 300 mm (12 in.) apart. Turn on the
monitor.
Notes:
1.
To prevent diskette drive read/write errors, be sure the distance between
monitors 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 reseller or IBM marketing representative.
If the problem remains, call for service.
Wrong characters appear on the
screen.
If the wrong language is displayed, update the BIOS code with the correct
language.
If the problem remains, call for service.
