EASY STEPS ON HOW TO TROUBLESHOOT YOUR PHONE

1.     Power Failure	The cell refuse to come up	ü First check the battery, if the battery still have enough strength to power the cell, ü Check the backup battery ü Check the ü Check the . ü Check the ü Check the ü Check power supply switch of the phone. ü Connect the phone to the charger, charge it for about five minutes and press the power switch to switch it on. ü Remove the jacket or the  housing, unscrew the cell phone and clean the board with fluid while cleaning, make you only clean the bus lines. ü Check if the charger connected have contact. Clean the leg of the connector together with the circuit board. Check if any of the components on board are intact if this efforts are made and no solution, change the board. Note: some board of the same manufacturer works together with each others. For instance NOKIA 3310 board can be used to replace NOKIA 3330 ETC. what you have consider first is the size of the cell phone board and the manufacturer.
2.  Partial    contact	The phone is not ON when receiving call.	At times, the problem lies on the bus line. Heat or dust might have blocked the bus line. The only solution to this is to remove the board, clean the bus line with fluid while cleaning make sure you don’t allow the fluid to touch the components of the board...
3.  Blunt screen	The screen is black ore broken	This problem arised when the cell phone is placed on where heat contact with the phone. After some minutes the optical with fibers will produce cladding liquid that will blunt the screen. The solution to this problem is to replace the screen with its own type. If the screen is with the board, that means the whole board must be replaced.
4.  No Message Display	If the phone is working but does not display any message	Remove the casing unscrew the phone cell and clean the display screen interface on the circuit board.
5.  No contact from the keypad	All the key pads cannot contact with the board.	If you press the key and they are not giving any response or display, anything while the phone is still working, check the tightness of the cell phone. If it is not tightened well, the keypad will not make any contact. If tightened and yet there is no solution, check the keys contact lines on the connectors on the board and clean them.
6.  Breaking message and unreadable messages	If the message on the screen is broken into two or partially broken when pressing any key, the cell phone displays half part of the message	Unscrew the phone, clean the phone with fluid and allow it to dry for some minutes then couple the phone.
7.  Battery brains not normal	This is a situation whereby the cell battery goes down faster than normal	If the battery is a new battery, change it and recharge for two or three times to obtain normal performance. If it is a new battery read from the voltage of the battery to see the voltage capacity. If the area is a variable coverage. This quickly drain the battery, unless user saves the area, the batter always drain fater.
8.  The battery is not charging	If there is current to charge the battery and the battery is not charging.	Check the alighnment of the battery to ensure that they are installed properly. Make sure the polarities are well collated and see contact, clean and dry. If there is no response, use another charger to discover where the fault lies. At times the charger may be bad. Finally check the charger control IC.
9.  blinking of Network Signals	This is when the signal symbol showing the Network signal is blinking or On / Off on the phone screen.	Check if the environment where user does not have enough coverage capacity to receive signal. Check if the signal receiver s receiving. Consider the configuration of the aility of the cell phone, adjust the antenna, clean the line bus with fluid.
10.   Contact with phone manufacturers	Some cell phones gives this information when services are required	With air and set them back. Charge and discharge the batter
11.   Loss memory	If the information stored in the memory is missing, phone cell cannot retain information to retain memory ….	There is a cell battery of the board that makes the cell phone after some hours of the information for 24 hours. When the battery is weak or bad the cell phone can no longer store or retain any information. Change the battery with its own Original type the battery is Ok after reading it with meter, recharge the normal battery of the cell because low current during charging affect through cell phone memory. The RAM may be bad.
12.  Not Network	The cell phone recognize the SIM card but cannot link to the base station	Check if the cell phone is not customized to one particular network. Check RF amplifier, RX filter TX mutual Coupler, Audio e.t.c.
