Troubleshooting
Chapter Four: Troubleshooting
Troubleshooting is how you determine what part of a complex system
(like a home theater system) is at fault when the system isnt working
how you think it should. When you troubleshoot a system, you diagnose
a problem by examining and eliminating possible causes until theres
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 aggravationthe
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 receiver because its 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 dont hear anything
through the speakers, its 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 signals path from source (such as a CD
player) to speaker.
You may also want to test the assumptions you made in step 1: maybe
you havent listened to your MD recorder in a while is there no
sound from it as well? This step will really help narrow down the
possible causes. Test all your connected components and eliminate
the ones where the problem doesnt occur. When youre done with
this step, youll probably have found the problem.
