Start 5 - IBM 3270 Maintenance Manual

Start 5
This is the entry point for using all of the
Problem Isolation Charts (PICs). At this point,
you have one or a combination of the following:
• An error code
• An audio error during the Power-On Self-Test
(POST)
• An undetermined problem
• A problem related to one device
Note:
For all problems, if you are entering this
procedure for the first time, begin with
"Checking Cable Connections" on the following
page.
If you are returning here from a PIC without
solving your problem and your symptom has not
changed, go to "Undetermined Problems" on
page 3-9999-1.
