System x3200 M2 Types 4367 and 4368: Problem Determination and Service Guide
Action
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 "Running the diagnostic programs" on page 156).
v If the server passes the video diagnostics, the video is good; see "Solving
undetermined problems" on page 229.
v (Trained service technician only) If the server fails the video diagnostics,
replace the system board.
1. If the monitor self-tests show that the monitor is working correctly, 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.
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. Non-IBM monitor cables might cause unpredictable problems.
2. Reseat the monitor cable.
3. Reseat the Remote Supervisor Adapter II SlimLine (if one is installed).
4. Replace the following components one at a time, in the order shown, restarting
the server each time:
a. Monitor
b. Remote Supervisor Adapter II SlimLine
c. (Trained service technician only) System board
1. If the wrong language is displayed, update the BIOS code with the correct
