General
In each service manual on Service Source, you will find
Flowcharts and/or Symptom Charts designed to help you
diagnose and repair Apple computers.
If you have narrowed the problem down to a particular
symptom, start with the Symptom Charts. Because cures are
listed in the order of most likely solution, try the first cure
first. Verify whether or not the product continues to exhibit
the symptom. If the symptom persists, try the next cure.
If you are not sure what the problem is, or if the Symptom
Charts do not resolve the problem, refer to the Flowcharts.
Diagnostic tools are also available to help you isolate a
hardware problem. Refer to the Diagnostics page of Service
Source, which you can access on Service Source CD or at
Service Source Online (http://service.info.apple.com).
If you require additional assistance, contact Apple Technical
Support.
