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 Problem Determination and Service Guide on the IBM System x Documentation CD 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. Reseat the Remote Supervisor Adapter II SlimLine.
5. Replace the following components one at a time, in the order shown, restarting
the server each time:
a. Remote Supervisor Adapter II SlimLine
b. (Trained service technician only) System board
The screen is blank.
1. If the server is attached to a KVM switch, bypass the KVM switch to eliminate it
as a possible cause of the problem: connect the monitor cable directly to the
correct connector on the rear of the server.
2. Make sure that:
v The server is turned on. If there is no power to the server, see “Power
problems” on page 86.
v The monitor cables are connected correctly.
v The monitor is turned on and the brightness and contrast controls are
adjusted correctly.
v No beep codes sound when the server is turned on.
Important:
In some memory configurations, the 3-3-3 beep code might sound
during POST, followed by a blank monitor screen. If this occurs and the Boot
Fail Count option in the Start Options of the Configuration/Setup Utility
program is enabled, you must restart the server three times to reset the
configuration settings to the default configuration (the memory connector or
bank of connectors enabled).
3. Make sure that the correct server is controlling the monitor, if applicable.
4. See the Problem Determination and Service Guide on the IBM System x
Documentation CD.
If
the problem remains, call for service.
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 on
the IBM System x Documentation CD).
v If the server passes the video diagnostics, the video is good; see the
Problem Determination and Service Guide on the IBM Documentation CD
that comes with your system.
v (Trained service technician only) If the server fails the video diagnostics,
replace the system board.
If
the problem remains, call for service.
