Is anything displayed on the monitor?
There is a problem with the system unit if:
•
A three or four digit error code appears. Find the code in “Responding to error codes” on page 141 and take the
action listed.
•
A box containing an error code and message appears. Follow the instructions in the message. For instructions on
using the Setup Utility, see “Using the Setup Utility” on page 29.
•
A blinking cursor appears. Check your Guide to HelpWare and All the Extras folder for information on obtaining
service.

The image on the screen is unreadable (the image is scrolling, blinking, or flashing). You may have selected a
monitor setting that your monitor does not support. Follow these steps to reconfigure your monitor:

unit back on.
