Monitor problems

Some Lenovo 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.

vFollow the suggested actions in the order in which they are listed in the Action column until the problem is solved.

vSee the parts listing in the Hardware Maintenance Manual to determine which components are customer replaceable units (CRU) and which components are field replaceable units (FRU).

vIf 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 the other video port.

 

3.

Try using a different monitor on the server, or try testing the monitor on a

 

 

different server.

 

4.

Run the diagnostic programs (see the Hardware Maintenance Manual). If the

 

 

monitor passes the diagnostic programs, the problem might be a video device

 

 

driver.

 

5.

Reseat the Remote Supervisor Adapter II SlimLine (if one is present).

 

6.

Replace the following components one at a time, in the order shown, restarting

 

 

the server each time:

 

 

a. Remote Supervisor Adapter II SlimLine (if one is present)

 

 

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:

vThe server is turned on. If there is no power to the server, see “Power problems” on page 73.

vThe monitor cables are connected correctly.

vThe monitor is turned on and the brightness and contrast controls are adjusted correctly.

vNo 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.Make sure that damaged BIOS code is not affecting the video; see the Hardware Maintenance Manual for information about recovering from a BIOS failure.

5.See the Hardware Maintenance Manual for information about solving undetermined problems.
