Page: 121 / 210

v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v
See Chapter 3, “Parts listing, System x3755 Type 8877 and 7163,” on page 25 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 “Running the diagnostic programs” on page 121).
v
If the server passes the video diagnostics, the video is good; see “Solving
undetermined problems” on page 175.
v (Trained service technician only) If the problem remains, replace the I/O
board, see “Removing the I/O board assembly” on page 68 and “Replacing
the I/O board assembly” on page 69.
The monitor has screen jitter, or
the screen image is wavy,
unreadable, rolling, or distorted.
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 following components:
a. Monitor
b. Remote Supervisor Adapter II SlimLine (if one is installed). See “Removing
the Remote Supervisor Adapter II SlimLine” on page 58 and “Replacing the
Remote Supervisor Adapter II SlimLine” on page 58.
3. 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 (if one is installed). See “Removing
the Remote Supervisor Adapter II SlimLine” on page 58 and “Replacing the
Remote Supervisor Adapter II SlimLine” on page 58.
c. (Trained service technician only) I/O board. See “Removing the I/O board
assembly” on page 68 and “Replacing the I/O board assembly” on page 69.
