Dct4 power on problem with battery but software connecting time localmode&testmode

THE LAST WEEK AM SEEN MANY POSTING IN ALL FORUMS
NOKIA DCT4(1200,1208,1650 Etc........)FLASHING COMPLETED AND WITH CABLE SHOW LOCAL MODE
BUT WITH BATTERY PHONE NOT POWER ON

THIS MY TECHNICIS
MAINYLY THIS CAUSE BSI RELATED PROBLEM
BUT 1650 IS DIFFERNT CAUSE
60%SOFTWARE PROBLEM 1650
SOLUTION
1)ERASE FLASH
2)FLASH LAST VERSION(MCU+PPM+CNT)
3)WRITE PM
4)UNLOCK&FULL FACTORY

HARDWARE SOLUTION
1)CHANGE BATTERY

2)RESOLDRING BATTERY CONNECTOR

3)CLEAN OR CHANGE BOTTON CONNECTOR

4)CHECK BSI WAYS

5)CHANGE BSI RESISTER

IF PROBLEM NOT SOLVED?
REFLOW OR CHANGE UEM
UEM CHANCE 40%


SAME PROBLEM FACED DCT4 ANOTHER MODEL HANDSET

6030 as you said but after 5 minute again not charging

THIS PHONE MAIN PROBLEM NUM-2 MARKED RESISTER

Local mode problem & test mode problem, some general facts

What is local mode?

Local mode is triggered either by a service battery / jig from Nokia being used to power the phone,
A faulty battery, a faulty phone or the phone has got "liquid ingress” also indicate local mode in display

See this picture

s in the above picture when BSI is grounded with a resistor of
5.1k to 7k1 and insert battery, nokia sets displays local/test mode on screen

By this way we can trigger the set in to local mode and software operation through USB


Local mode is triggered for reading & writing phone pm area (EEPROM),
File system formatting etc.

What is test mode?

Test mode is for doing file system removing like full factory defaults
Also can do pm area re-writing and for unlocking the phone


Some phones displays either of these modes directly when battery is inserted to the phone
and we gets in this condition for repairing

This may be either by a faulty battery or damaged hardware in the handset.
We can assume this is a BSI related fault

TEST THE PHONE WITH A WORKING BATTERY


Now what is BSI?

BSI, the thermistor used to sense the battery temperature and shut down the charger
Their is an internal circuit from power IC to BSI lead of battery
this circuit manages charging mechanism and battery sensing.

Faulty parts in this BSI circuit may lead to the local/test mode

Or finally we have to suspect power ic






Here NOKIA 1200 schematic is used to illustrate BSI way and possible reasons for this fault.

he blue colored parts are related to the BSI function .we have to trace from battery connector, capacitors, and then other parts. These parts can be identified by reading the higher level schematic of the phone. By following this logic you may be able to trace local mode in any nokia phone

NOKIA 6233 DISPLAY WHITE PROBLEM CHECKING METHODE HERE

1)CHECK OR CHANGE DISPLAY

2)RESOLDRING DISPLAY CONNECTOR

3)CHECK VIO 1.8 VOLT

THIS VIO VOLT MISSING?
A)CHECK RED MARKED COIL
B)JUST MAKE THIS JUMBER LIKE THIS PICTURE

4)CHECK FM LCD 2.8 Volt

THIS FM LCD 2.8 Volt MISSING?
A)CHECK THIS RED MARKED COIL
B)CHANGE THIS FM LCD 2.8 VOLT DRIVER

5)CHANGE DISPLAY EMI FILTER(2Nos)

6)LAST CHECK RAP3G REFLOW OR REBALL THIS CHIP
