Monitor and Terminal Problems
If the system starts up but has no startup display when you turn on the system,
refer to Table 9-7.
Table 9-7
Troubleshooting Monitor and Terminal Problems
Possible Cause Action
The monitor or terminal is not turned on. Check that the monitor or terminal is turned
on.
Make sure that all cables are connected at
both ends.
The monitor or terminal brightness and
contrast controls are incorrectly set.
Adjust the monitor or terminal contrast and
brightness controls.
The power cord is not connected. The power
cord may be faulty. The power cord socket
may not be working.
Make sure that all the power cords are
connected correctly at both ends. Try a
power cord that works or test the power
socket with an appliance that works.
VGA controller settings may be incorrect. Combining multiple VGA controllers will
produce unpredictable results, and use of
multiple VGA controllers is not recommended
or supported.
The terminal or monitor fuse may have
blown.
Replace the blown terminal or monitor fuse.
Refer to the terminal or monitor
documentation.
The port to which the terminal or monitor
connects may not be the correct one.
Ensure that your monitor cable is plugged
into the connector of your VGA card, not the
connector on the system board.
The port to which the terminal or monitor
connects may be faulty.
Try connecting the terminal or monitor to
another system using the same terminal or
monitor cable. If the terminal or monitor
works, the port to which the terminal or
monitor was connected is faulty. Contact
your service representative.
