v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v See the parts listing in the Problem Determination and Service Guide to determine which components are customer replaceable units (CRU) and which components are field replaceable units (FRU). v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a trained service technician. Symptom Action The monitor works when you turn on the server, but the screen goes blank when you start some application programs. 1. Make sure that: v The application program is not setting a display mode that is higher than the capability of the monitor. v You installed the necessary device drivers for the application. 2. Run video diagnostics (see the Problem Determination and Service Guide for information about running the diagnostic programs). If the video passes the video diagnostics, the video is good; see the Problem Determination and Server Guide for information about solving undetermined problems. The monitor has screen jitter, or 1. If the monitor self-tests show that the monitor is working correctly, consider the the screen image is wavy, location of the monitor. Magnetic fields around other devices (such as unreadable, rolling, or distorted. 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 305 mm (12 in.) apart, and turn on the monitor. Notes: a. To prevent diskette drive read/write errors, make sure that the distance between the monitor and any external diskette drive is at least 76 mm (3 in.). b.

and
any
external
diskette
drive
is
at
least
76
mm
(3
in.).
b.
Non-IBM
