5.1.1 Symptoms at the case of Fault

1. Symptom 1 is no work at all, including boot failure and no response after a service

power is supplied and the phone power switch is pressed.

2. Symptom 2 is no work at all; at that time, a current may be measured after the power

is supplied and the phone power switch is pressed, but no on/off message regularily

provided, no key backlighting, no display backlighting, no vibration, and no ringing

appear.

3. Symptom 3 is some features malfunction, including key failure, irregular display

(displayed message error, full black, full white, and wrong font in the LCD and the

like), no sound, and dialing failure, but work

5.1.2 Repair Procedures

Repair the malfunctioning mobile phone according to the following process:

1. To find out the cause before repair

First of all, ask the user when the phone failed, which fault phenomenon occurred, and

which irregularity was caused those days before repairing the phone. Observe whether

an obvious crack and a damage are caused on the appearance of the mobile phone. A

broken antenna, bald keypad and so on, for example, may approximately result in the

phone failure; in addition, know whether the phone to be repaired is a secondhand one,

whether it was repaired at other site, how long it has been used, and what its service life

is. A technical staff experienced may easily determine which portion and part failed,

knowing the cause of failure, to improve the maintenance quality and effficiency.

2. To record the failure

Nothing more than no boot, immersion in water, falling, no display and the like leads to

failure, but they are likely very different from each other. To record the failure is to know

the phenomenon from said failure and to recover for no argument between the user and

the maintenance personnel. Then, further check whether any other failure exists in the

phone for fear of oncoming dispute after repair.

3. To record the phone model to be repaired and the IMEI code

The IMEI code of each phone as the name of each phone is essential for correct

handover.

4. To master the tips on how to operate the phone to be repaired

Technical staff to repair mobile phones may not set up and use a phone as the

ARES CONFIDENTIAL PROPRIETARY.

泓越科技股份有限公司 Ares Communications Technology . , INC. FILE : 2049 service manual level3 v1.4 ENG.DOC

technician to repair cars may not drive. So, it is necessary to well know the operation

guide.

5. To repair the phone at a working room

If you are not confident, do not repair it in front of the user, but you may take it apart to

observe for fear of another failure caused caused by erroneous operation due to

nervousness.

6. Simplicity comes before complication.

7. Check the software version.

8. Check whether the audio frequency signal I/O interfaces, SIM card, ring, keypad, display panel,

microphone,receiver, vibrator and the like work normally.

9. Disassemble the phone in order. Refer to chapter 4 for the detailed procedures of disassembly and

assembly.

10. Keep a service log.

5.1.3 Basic Environment for Repair

1. Basic Environment:

A quiet environment is necessary for repairing the mobile phone; arranged environment

simple and bright, well situated temperature and humidity of air, and no dust and no

smoke are required.

2. Arrangement of the workbench:

A static mat insulated should be laid on the workbench. Back up a parts shelf with many

small drawer to put the corresponding fittings and the members disassembled in, a

workbench lamp, and a magnifier.

3. Points for Attention:

Every time before you take apart the phone, touch the ground wire. Do not put on

clothes with chemical fiber easily producing static electricity at the time of repair.

5.5.2 Typical repair flow for RF

If the RF part of the phone needs repairing, an oscilloscope, a spectrum analyzer, a computer, an RF synthetic

instrument, a power supply, and related testing software DBService are required, as shown

below:

Points for Attention:

1. At the time of RF testing, an Inline mode in DBService is generally selected, and a channel

(ARFCN) required, Power Level, AFC values, and RX or TX mode should be set.

2. General external power voltage range set: 3.8V ~4.2V DC

3. DBService may be used to test the phone only at test mode. At normal mode, press on the keypad

<*>,<#>, and <power on> at one time to enter the test mode.

4. At the time of PCB operation, wear an anti-static band to prevent the parts from being damaged.

5. Before testing, set up the testing instruments.

5.7 Detection after the Mobile Phone Is Repaired:

Points for attention after the appearance is remedied:

1. Check whether the front and rear housings and the Lens are scraped. (Determine with the user

whether the appearance of the phone to be repaired is scraped.) No fingerprint should be stained

on Lens and LCD.

2. Check whether the front and rear housings of the phone coincide with each other. No clear gap

and crack should be caused.

3. Touch all the keys of the phone for comfort ability.

4. Visually check whether the Spring Contact Plate of battery of the phone is distorted.

5. Visually check whether the LCD is askew using the backlighting is bright after the phone is

switched on.

6. At the time of rear housing replacement, tear off the labels (including IMEI Label, CIT Label, and

DSN Label) from the rear housing, and then stick them on the new rear housing. Before you tear

off the labels, heat them a bit using an air gun in order to prevent the labels from being damaged.

(Note: The heating cannot be too long in order to prevent the rear housing from being burned.)

Functional test and verification are necessary after the board is repaired.

1. All the phone’s functions check:

Observe the performance of the entire phone. Verify by calling and answering a call whether the

call functions, the tone quality, and the ring are in good condition; further, determine through the

manual test functions whether the related functions of the phone are in good condition.

2. S/W test:

Perform a test for configuration of the software. The saving function of the phone processed for

FLASH ROM and EEPROM may be check by dialing. The function list may be verified by

adjustment. Through charging, further verify whether the logic part runs normally, and observe the

capacity of battery for detection function so as next to determine whether the logic part runs

normally.
