Trouble Shooting Guide, Electrical
1 Abstract
The purpose of this document is to provide a sequence of repair actions associated with
different failure modes. The repair actions are listed in order of their probability of creating a
successful repair. The first action has the highest probability, and subsequent actions have
lower probabilities. The intention is for the repair technician to implement the first repair
action and then retest the phone. If the phone continues to fail the same test, then the
technician should continue to the second repair action. If the phone continues to fail the same
test after all of the repair actions are exhausted, then the phone will be considered not
reparable at this level.
This document should be used only after the steps specified in the Mechanical Trouble
Shooting Guide have been exhausted for the given problem area.
