1General

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.
