If the Charge is not Functioning
There are several possible damage if the Charge does not function: The damage occurred on the rechargeable device (charger) battery itself, try your charger on tools other similar device to find broken or not. Battery on your phone is broken so that battery can no longer be refilled. Check whether the connectors on the battery recharging your phone is still good. Then we had to check and test on the phone itself.
If The Phone Signal is Not Stable
very frustrating if we have a phone but the signal is not stable. some time there, at a time when others did not exist.
If you have a signal on the phone is not stable, sometimes strong, sometimes weak.
Please follow the steps I wrote in this post.
Repair procedures:

Solution if Your Phone No Signal
When we insert the SIM card and turned on the phone, then there is no signal or a network that appears on the LCD device.
check the first component of the antenna and antenna connector, ensure that well connected. Especially if your phone is a phone with internal antenna, associated with the mainboard PCB or through the contact of two elastic pointer, if the pointer is in contact contact the ugly, the problem that arises is the lack of a network (no network) and a bad signal reception signals even lost (no signal).
Especially with the engine knock or fall into the water, bad contacts and oxidation will occur at the contact pointer. Antenna switch is the only way to rnenerima and send a signal, if damaged or soldering pins is faulty, would appear the problem is not the network or transmission.
Next we tried to find the network on the phone with the manual method, if the method fails in this manual network search, so we can be sure there is a problem in RF IC (HAGAR), change the RF IC (HAGAR) was then the problem will be over.
Networking can be searched by manual method sometimes fails, can not even connect to the network as well. This phenomenon is caused by problems RF IC (HAGAR), AUDIO IC (COBBA). If the module COBBA appeared an error, most likely was caused by his BGA soldering and units around the poor, or lack of flow, whereas most of the problems HAGAR-unit due to a bad unit.
If looking for a network with the manual method on our mobile phones have only 1 (one) operator / mobile service providers only, then there is a problem with the IC VCO, replace the VCO IC was the problem to be completed.
After the testing and repairs done on our hardware but still no signal / missing, then we went to the software. We flash your phone in accordance with the type of mobile phone and mobile phone software version or the version before the newer software (upgrade)

Solution If Your Phone is Not Vibrating
How upset if we use mobile phone that can vibrate with the original well, but at one point were damaged, so can no longer vibrate. This can be caused by cell phone or have fallen short of components resulting from the abnormal voltage or battery charger is short, and other things.
Components Viberator
Step One, which do if your phone does not vibrate is to see the menu settings on the phone vibrate if sedah enabled the menu. After that open the phone casing and see viberator components (vibrator) contained therein. This viberator generally attached to the phone casing, and can be measured using multitester. Functioning Viberator will rotate if the measure with multitester.
If you've damaged components can be replaced with a new vibrator. At the time of installation should be placed back viberator correctly and viberator legs raised slightly so attached to the PCB to prevent contact loss that causes vibration function to be disrupted.
Controller vibrator
Further examination is the component that controls the vibrator. In this case the controller is different vibrators on each type of phone:
- At Nokia DCT3 controller is a CPU that is connected through the user interface to the IC vibrator.
- At Nokia DCT4 controller is IC Power (Universal Energy Management) that is connected to the vibrator.
- At Nokia BB5 3G is the controller IC Power (IC retu)
- And other types of phone pad controller vibrators are generally CPU (Central Processung Unit) which is connected through a transistor driver to the vibrator.
- Check the components Vibrator
- Check controller component Vibrator
- Check connecting lines with IC controller vibrator.

Solution When The Phone Does Get Wet
If you have things like that do not panic, the mind can be stressful. In this article, we will provide a way of handling a wet cell phone.
If your phone is new with warranty, forget about the warranty. Service Center for phone vendors obviously will refuse warranty if the phone has proven to be exposed to fluids, although the warranty seal still intact. A consumer has rejected the warranty claim for a damaged cell phone, on the grounds wet. And cell phone was never exposed to further research airSetelah cell phone was damaged because it is often exposed to cold ocean, which can also cause corrosion on the phone.
Drain Phone
First steps to do if the phone is under water, try to quickly pull up and immediately the phone battery. Immediately dry the outside of the phone with a clean rag or tissue, so that water does not enter more and more into the phone. If you do not intend to open the inside of the phone, you can use a hair dryer to dry it.
Once outside the dry section, casing and PCB inside the phone must be opened to drain the water remains trapped inside. If not immediately dried, then the components in it will experience corrosion and phone can not be repaired anymore. Especially if exposed to sea water, the components will experience faster corrosion.
To open the lock bolts are usually required phone casing eyed T6 screwdriver. In a candy bar phone models are usually easy to open, while the clamshell models performed better suit.
Once the phone is open, clean the remaining water with cleaning fluid such as paint thinner, IPA, or alcohol. To dissolve the dirt and residue attached to the components in the PCB, can use a toothbrush or with the help of PCB cleaning (ultrasonic Cleaner).
Power Supply
Once dry, plug it in again and try to turn on the phone using a battery or by using the Power Supply. By using the Power Supply, which shorted out components exposed to water can be easily detected. If not, then watch the movement of currents in the Power Supply. If no reaction, the possibility of problems at the circuit power supply regulator IC on the phone or on the switch on / off the phone.
If there is a reaction to the Power Supply current, the next step to do data repair software on the phone. Fashing trick is to use the software and the appropriate data cable. If the flashing process is successful, usually the phone will light up again. When the flashing process fails, there is the possibility of damage to the phone's processor and memory that needs to be checked further hardware or replacement of these components.
