1 General Information
The Mechanical Troubleshooting Guide outlines the mechanical repairs that can be made to try
and fix the common failure areas that are seen in the field. The subsections under “General
Information” are steps that apply to all phones that are being looked at for repair at a mechanical
level. To gain a complete understanding of how to test and repair a specific failure, this
document should be used in conjunction with the Test Instructions, Mechanical and the Working
Instructions, Mechanical.
1.1 Liquid Damage
Before any repair is performed, an inspection of the water indicator label should be made. If the
water indicator label is pink, red, or has a reddish tint to it, this is an indication of possible liquid
exposure. If the water indicator label suggests possible liquid exposure, disassemble the unit and
inspect the circuit board and its components for corrosion or oxidation from liquid damage. If
evidence of liquid damage is present, no repair actions should be taken. Please consult your local
company for additional handling instructions.
The following images show the location of the water indicator label and what an activated and
non-activated water indicator label looks like.

1.2 Flashing
Before any repair is made, a phone should be flashed to see if that fixes the problem. If the first
attempt at flashing a phone is unsuccessful, check whether the system connector is dirty,
oxidized, or damaged. If the system connector is damaged, handle the unit according to your
local company directives. If the system connector is dirty or oxidized, clean it and try reflashing
the phone. If the second attempt at flashing is not successful, handle the unit according to your
local company directives.
1.3 Unrepairable at the Mechanical Level
If the Mechanical Troubleshooting Guide is exhausted and the cause of the failure was not
determined or the failure cannot be repaired at this level, handle the unit according to your local
company directives.

2 Appearance Problems
Troubleshooting Steps
NOTE! The flip assembly is considered a user-
removable part and may not be present on a
phone when it comes in for repair. If the
phone is going back to the original customer
and the flip assembly was not present when
the phone came in for repair, the flip
assembly should not be replaced.
Otherwise, if flip assembly is not on a unit,
install one.
1. Check for cosmetic damage on the cosmetic surfaces
of the phone. Make sure that the seams between the
front cover and back cover fit together correctly.
2. Also check for cosmetic damage and fit issues with
the keyboard flip, the keyboard’s flip hinge cover,
and the battery cover. Replace damaged
components as necessary.

Troubleshooting Steps
3. Check the side keys, the jog dial, the memory stick
cover, the audio jack cover, the RF port cover, the
cosmetic screw covers, the decretive camera
window, and the IR window for damage, marks, and
correct fit. Replace components as necessary.

3 Network Problems
• Perform sections 1.1 (Liquid Damage) and 1.2 (Flashing) before proceeding
Troubleshooting Steps
1. If a network problem exists, check whether the SIM
connector is damaged, dirty, or oxidized. If the SIM
connector is dirty or oxidized, clean it. If the SIM
connector is damaged, send the unit to a location
approved to perform electrical repairs.
2. Check whether the spring fingers of the antenna
contact on the circuit board are damaged, dirty, or
oxidized. If the spring fingers are dirty or oxidized,
clean them. If the antenna contact is damaged, send
the unit to a location approved to perform electrical
repairs.
3. Check whether the contact pad on the antenna is
damaged, dirty, or oxidized. Clean the antenna’s
contact pad or replace the antenna as necessary.
4. Check whether the external RF port is damaged,
dirty, or oxidized. If the RF port is dirty or oxidized,
clean it. If the RF port is damaged, send the unit to a
location approved to perform electrical repairs.
• Refer to section 1.3 (Unrepairable at the Mechanical Level)

4 On/Off Problems
• Perform sections 1.1 (Liquid Damage) and 1.2 (Flashing) before proceeding
Troubleshooting Steps
1. If the display is not illuminated and the customer’s
battery is present with the phone, check that the
contact pads on the battery are not damaged, dirty, or
oxidized. Clean the contact pads or replace the
battery as necessary.
2. Check whether the phone’s battery connector is
damaged, dirty, or oxidized. If the battery connector
is dirty or oxidized, clean it. If the battery connector
is damaged, send the unit to a location approved to
perform electrical repairs.
3. Check the tactile response of the power on/off key.
The key should feel like it is clicking when it is
depressed (most likely a click will not be heard). If
the power on/off key does not feel like it is correctly
responding when depressed, disassemble the phone,
pull the power key out of its hole in the frame, and
check for debris around the key (the key can be
pulled back out of its hole, but it cannot be removed
from the back cover). If necessary, clean the key
hole and around the key. If the key is damaged,
replace the back cover.

Troubleshooting Steps
4. Check that the power on/off key’s switch has a
tactile response. The switch should feel like it is
clicking when it is depressed (most likely a click will
not be heard). If the power key does not feel like it
is correctly responding when depressed, clean the
switch and test its responsiveness again. . If the
switch is still not responding correctly or damage to
the switch is visible, send the unit to a location
approved to perform electrical repairs.
• Refer to section 1.3 (Unrepairable at the Mechanical Level)
5 Stylus Problems
• Perform sections 1.1 (Liquid Damage) and 1.2 (Flashing) before proceeding
Troubleshooting Steps
1. Check that the stylus is not damaged and does not
fall out of the stylus holder. Replace the stylus and
the stylus holder as necessary.

Troubleshooting Steps
1. If an audio problem is determined to be with the
front speaker, check that the front speaker’s external
port is not clogged (The port must be checked from
the inside of the front cover). Replace the front
speaker’s speaker cloth and clean the port as
necessary.
2. Check whether the front speaker’s holder or the
holder’s mating latches on the front cover are
damaged. If the front speaker’s holder or the front
cover is damaged, replace the appropriate part.
3. Check whether the front speaker is damaged or dirty.
Clean or replace the front speaker as necessary.
NOTE! If the front speaker is replaced, the front
speaker audio reset software must be run on
the phone. Instructions for running the front
speaker audio reset can be found in the Test
Instruction, Mechanical.
