1 General

This document outlines the mechanical repairs that should be made in an attempt to fix the common failures that are seen in the field. To gain a complete understanding of how to test and repair a unit, this document should be used in conjunction with the Test Instructions, Mechanical and the Working Instructions, Mechanical.

NOTE! A unit should always be inspected for liquid damage and flashed with latest software before using the

Mechanical Trouble Shooting Guide. Refer to the Mechanical Test Instructions for details regarding upgrading software.

NOTE! If all of the repair actions listed in this document for addressing a problem have been performed and a unit still

is not working, handle the unit according to your local Sony Ericsson Representative.

Misuse and other no warranty issues

A phone that is damaged due to misuse is not covered by warranty. This section shows many of the signs of misuse that are seen in the field. Please refer to local directives on how a phone that appears to be damaged due to misuse should be handled.

Below are some examples of damage due to misuse that are not covered by warranty.

Front window broken due to

misuse.

LCD cracked due to drop. Clear scratches Mark after drop

1.1.1 Liquid Damage Inspection

Before any tests are performed, an inspection of the liquid intrusion indicator should be made. If the liquid intrusion indicator is red, this is an indication of possible liquid exposure. If the liquid intrusion indicator suggests liquid exposure, please consult your local SEMC representative for handling instructions.

Location of the liquid intrusion indicator

The following pictures show the difference between an indicator that has been in contact with liquid and one that has not.
