Trouble Shooting Guide, Electrical
1 General
The purpose of this document is to indicate the electrical level repair actions associated with
the different failure symptoms.
For symptoms that have multiple repair actions, 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 actions from the Mechanical Trouble Shooting
Guide have been exhausted for the specific symptom.
Voltage, current, and resistance information is provided for some symptoms to enable faster
repairs. Perform current measurements using a dummy battery and power supply with digital
current display. The phone should be fully assembled. Perform voltage and resistance
measurements with a multimeter. Purchasing this equipment and performing these
measurements is optional but recommended.
