Characterizing the problem
This is your first step in diagnosing the problem you are having with your Profile XP
Media Platform. The information presented here and the questions asked will enable
you to:
• Determine the nature of the problem
• Direct you to the area of the manual that deals more specifically with the problem
you are experiencing
You will also find brief discussions of the diagnostic aids available on the media
platform. In cases where the error message carries with it the remedy to the cause, you
will not need to go beyond this chapter.
Localizing the problem
In determining the nature of the problem, there are four questions that will in most
cases help you localize the problem to one of the three major subsystems.
What was the media platform doing when the problem occurred?
Another way to ask this would be, “What were you doing with the media platform
when the problem occurred?” or “How were you using the media platform when the
problem occurred?” This can include “When did the problem occur?”
• Does the problem occur at start-up?
Any failure before the desktop appears is most likely a Windows NT boot problem. If
you are experiencing boot problems, refer to Chapter 2, Troubleshooting Windows NT
boot problems, which covers the potential problems you can encounter during the
WindowsNT boot sequence.
• Can you record and play video, audio, and timecode?
Record and play problems can have a number of causes. The most frequent problems
result from a change in configuration, or cables being accidentally disconnected or
misconnected. Refer to Chapter 3, Troubleshooting video problems, Chapter 4,
Troubleshooting audio problems, or Chapter 5, Troubleshooting timecode problems
for help determining those problems.
If an automatic controller is used to operate the media platform, refer to Chapter 9,
Troubleshooting channel control problems for dealing with possible problems caused
by controller interface problems.
• Is there a problem with the video network?
If you are having network problems such as an inability to access other Profile
systems on the network see Chapter 7, Troubleshooting video network problems,
which deals with possible problems in the fibre channel or ethernet video network
systems.
