5 Solving Problems 90
• Are the video monitor switch settings correct?
• Is the video monitor signal cable properly installed?
• Is the onboard video controller enabled?
If you are using an add-in video controller board, do the following:
1 Verify that the video controller board is fully seated in the server
board connector.
2 Reboot the system for changes to take effect.
3 If there are still no characters on the screen after you reboot the
system and POST emits a beep code, write down the beep code
you hear. This information is useful for your service representative.
4 If you do not receive a beep code and characters do not appear,
the video display monitor or video controller may have failed.
Contact your service representative or authorized dealer for help.

• Are the brightness and contrast controls properly adjusted on the
video monitor? See the manufacturer’s documentation.
• Are the video monitor signal and power cables properly installed?
If the problem persists, the video monitor may be faulty or it may be
the incorrect type. Contact your service representative or authorized
dealer for help.

• Did you press the power button?
• Is the power on light lit?
