Troubleshooting
Monitor Problems Action
Blank screen and one
beep. Verify that:
1. The monitor power cable is connected to the
display and to a working electrical outlet.
2. The monitor is turned on and the Brightness and
Contrast controls are adjusted correctly.
3. The monitor signal cable is connected correctly to
the video connector on the system board or to the
video adapter.
If the screen remains blank, run the monitor self-tests.
If those tests show the monitor is OK, have the system
serviced.
Blank screen, continuous
beep, or more than one
beep. Have the system serviced.
Only the cursor ( _ )
appears. Have the system serviced.
Wrong characters appear
on the screen. Have the system serviced.
General Problems Action
Problems such as broken
cover locks or indicator
lights not working. Have the system serviced.
Intermittent Problems Action
A problem occurs only
occasionally and is
difficult to detect. Verify that:
1. All cables and cords are securely connected to the
rear of the system and attached options.
2. When the system is turned on, air is flowing from
the rear of the system at the fan grill. If there is no
air flow, the fan is not working. This causes the
system to overheat and shut down.
3. The last external device in each SCSI chain is
terminated correctly. (See “SCSI Drives” on
page 218 for more information about SCSI
terminators.)
If these items are correct, the next time it occurs, make
a note of what the system is doing when the problem
occurs again. Then have the system serviced.
