A.10.4 Monitor Display Is Abnormal
Description
Jittering, unreadable, rolling or twisted image is displayed on the monitor screen.
Solution
To solve the problem, proceed as follows:
1. If monitor self-test indicates that the monitor works normally, consider the position of the
monitor. The magnetic field around other devices (such as transformers, electronic
devices, fluorescent lights, and other monitors) may cause screen jitters, image
fluctuation, or unreadable, rolling or twisted image.
2. Close the monitor if this condition happened. When you move a color monitor, the color of
the screen may be distorted. Move the device and monitor. Make sure that the distance
between them is at least 305 mm.
3. Turn on the monitor. If the problem persists, replace the monitor or ATCA-7150. For details
on how to replace the monitor, refer to the document shipped with th e monitor that you
use.
