interpreting the Utility Results
If only one module cannot communicate on HP-MSIB, that module is faulty. Refer to the
appropriate service manual for troubleshooting and repair information.
If none of the elements on the HP-MSIB can communicate, either a module is disrupting the
entire HP-MSIB, the mainframe HP-MSIB circuits are faulty, or the display instrument has a
faulty HP-MSIB interface and the utility is giving erroneous results. Use the following steps to
further isolate the problem.
1. If an abnormal CRT screen is a symptom, refer to both the HP 70001A Mainframe Service
Manual and to the HP 70205A and HP 70206A Graphics Displays Service Manual for
further troubleshooting and repair information.
2. If flashing error lights are a symptom, the faulty element or mainframe can be isolated by
using the steps given below.
