36 Solving Problems
Power Light Does Not Light
Check the following:
q
Is the system operating normally? If so, the power LED is probably defective or the cable
from the front panel to the Workstation board is loose.
q
Are there other problems with the system? If so, check the items listed under ”System
Cooling Fans Do Not Rotate Properly”.
If all items are correct and problems persist, contact your service representative or authorized
dealer for help.
No Characters Appear on Screen
Check the following:
q
Is the keyboard functioning? Check to see that the “Num Lock” light is functioning.
q
Is the video monitor plugged in and turned on?
q Are the brightness and contrast controls on the video monitor properly adjusted?
q
Are the video monitor switch settings correct?
q
Is the video monitor signal cable properly installed?
q Is the onboard video controller enabled?
If you are using an add-in video controller board, do the following:
1. Verify that the video works using the onboard video controller.
2. Verify that the video controller board is fully seated in the Workstation board connector.
3. Reboot the system for changes to take effect.
4. 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.
5. 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.
