Troubleshooting the Video Subsystem
Problem
• Monitor is not working properly.
• Video memory is faulty.
Action
1
Check the system and power connections to the monitor.
2
Determine whether the system has an expansion card with a video output
connector.
In this system configuration, the monitor cable should normally be
connected to the connector on the expansion card,
not
to the system’s
integrated video connector.
To verify that the monitor is connected to the correct video connector,
turn off the system and wait for 1 minute, then connect the monitor to the
other video connector and turn the system on again.
3
Determine whether the system has monitors attached to both the front
and back video connectors.
The system supports only one monitor attached to either the front or back
video connector. When a monitor is connected to the front panel, the
back-panel video connector is disabled.
If two monitors are attached to the system, disconnect one monitor. If the
problem is not resolved, continue to the next step.
4
Run the appropriate online diagnostic test. See "Using Dell PowerEdge
Diagnostics" on page 167.
If the test runs successfully, the problem is not related to video hardware.
If the test fails, see "Getting Help" on page 179.
