ATCA-7350 Installation and Use (6806800G59G) 181
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 apart. 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. 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-7350. For details
on how to replace the monitor, refer to the document shipped with the monitor that you
use.
