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 volta ge and re sistance measu rements with a multimeter. Purchasing this equipment and performing these measurements is
optional but recommended.
Perform current measurements using a
dummy battery and power supply with digital
current display. The phone should be fully
assembled.
Perform voltage measurements with a
multimeter.
Perform resistance measurements with a
multimeter.
