Monitor or video problems
Some IBM monitors have their own self-tests. If you suspect a problem with your
monitor, see the documentation that comes with the monitor for instructions for
testing and adjusting the monitor. If you cannot diagnose the problem, call for
service.
Note: SLES 11 SP1 supports only Matrox G200eR with VESA driver. Go to Video
configuration interface for other resolutions if needed.
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 4, “Parts listing, System x3100 M4 Type 2582,” on page 151 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
Testing the monitor
1. Make sure that the monitor cables are firmly connected.
2. Try using a different monitor on the server, or try using the monitor that is being
tested on a different server.
3. Run the diagnostic programs. If the monitor passes the diagnostic programs,
the problem might be a video device driver.
4. Replace the following components one at a time, in the order shown, restarting
the server each time:
a. (Trained service technician only) System board
The screen is blank.
1. Make sure that:
v The server is turned on. If there is no power to the server, see “Power
problems” on page 90.
v The monitor cables are connected correctly.
v The monitor is turned on and the brightness and contrast controls are
adjusted correctly.
2. Make sure that the correct server is controlling the monitor, if applicable.
3. Make sure that damaged server firmware is not affecting the video; see
“Recovering the server firmware” on page 142.
4. See “Solving undetermined problems” on page 147.
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 94).
v If the server passes the video diagnostics, the video is good; see “Solving
undetermined problems” on page 147.
v (Trained service technician only) If the server fails the video diagnostics,
replace the system board.
