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.
