Monitor Problems
The power light on the monitor communicates codes that can help you
determine whether there is a problem. The following table lists the codes
for the monitor power light. For more information, see the documentation
that came with your monitor.
Basic Checks:
•
Run the monitor self-test as instructed in the monitor user’s guide.
•
While diagnosing the problem, connect the monitor power cable
directly to a known working electrical outlet to ensure that the monitor
turns on. Do not connect it to a power protection device, UPS, power
strip, or extension cord.
•
Ensure that the monitor power cable is firmly connected, verifying
that the power cable is adequately connected at the monitor and to
the electrical outlet.
•
Test the electrical outlet: ensure that the electrical outlet is working by
testing it with a different device such as a lamp.
•
Test the power cable: swap the power cables between the computer
and the monitor to see whether the problem symptoms change.
