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, Type 4364 or Type 4365 server,” on page 59 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 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 32.
v The monitor cables are connected correctly.
v The monitor is turned on and the brightness and contrast controls are
adjusted correctly.
v Only a single beep sounds 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. Make sure that damaged BIOS code is not affecting the video; see “Recovering
from BIOS update failure” on page 46.
5. See “Solving undetermined problems” on page 57.
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 37).
v If the server passes the video diagnostics, the video is good; see “Solving
undetermined problems” on page 57.
v (Trained service technician only) If the server fails the video diagnostics,
replace the system board.
