SBXL52: Hardware Maintenance Manual and Troubleshooting Guide
The screen is wavy,
unreadable, rolling, distorted,
or has screen jitter.
1.
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 305
mm (12 in.) apart. Turn on the monitor.
