Chapter 5: Troubleshooting
When there is a trouble which may indicate a malfunction, perform
troubleshooting using the following procedure. Troubleshooting
is how you determine what part of a complex system (like a home
theater system) is at fault when the system isn't working how you
think it should. When you troubleshoot a system, you diagnose a
problem by examining and eliminating possible causes until there's
only one left. Troubleshooting is easiest when you start with the
most obvious, most common, and most likely and work from there.
Diagnosing your own problems can save you time and aggrava-
tion—the better you understand how to troubleshoot and adjust
your own system, the less time you have to:
¶ spend on the phone with a customer service representative
¶ do without your player because it's "in the shop"
There are some basic steps to good troubleshooting:
1.
Verify the exact conditions when the problem occurs.
This is the most important step in troubleshooting. Whether
you fix it yourself or have to describe it to a technician, you are
much more likely to really solve the problem if you know the
exact circumstances surrounding the problem. For example, if
you don't hear anything through the speakers, it's useful to know
if it only happens when you are listening to CDs. Knowing that
eliminates the speakers themselves as part of the problem. The
more you know about when a problem occurs, the more likely
it is that you or the technician can solve it.
2.
Check each part of the signal path from source to speakers.
You may also need to test the assumptions you made in step 1:
