v If an action step is preceded by "(Trained technician only)," that step must be performed only by a trained
technician.
v Go to the IBM support website at http://www.ibm.com/supportportal/ to check for technical information, hints,
tips, and new device drivers or to submit a request for information.
Symptom
The server goes directly to the
POST Event Viewer when it is
turned on.

Monitor and video problems

Use this information to solve monitor and 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.

Testing the monitor.
Action
1. Correct any errors that are indicated by the operator information panel or LCD
operating panel assembly (see "Operator information panel" on page 20
or"LCD operating panel assembly" on page 21).
2. Make sure that the server supports all the microprocessors and that the
microprocessors match in speed and cache size. To view the microprocessor
information, run the Setup utility and select System Information > System
Summary > Processor Details.
3. (Trained technician only) Make sure that microprocessor 1 is seated correctly.
4. (Trained technician only) Remove microprocessor 2 and restart the server.
5. Replace the following components one at a time, in the order shown, restarting
the server each time:
a. (Trained technician only) Microprocessor
b. (Trained technician only) System board
Action
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. (Trained technician only) Replace the system board.
