Masalah Keypad Handphone

Phone keypad problem, there are several kinds, although very rare damage on the phone keypad. Here are some types of damage on the phone keypad in conjunction with the solution:
If either button is pressed but does not work, for example the number three, we check and test voltage (volts) on the third button, then the voltage (volts) which is 0 V out, it means there is no voltage (volts) out. damage can be caused by poor connectivity song, let us clean the brass plates are used to pad on the PCB by using ordinary pencil eraser we use. If still not successful then we do jumpers with: For instance is the number three is not working then this figure with figure 2 jumperlah 3 (horizontal) and number 6 (vertical), circular brass plate outside jumpers''between the number three to number two ( horizontally), then the scope of jumpers 'from' brass plate between the number three to number six (vertical).
All the buttons do not work 'alias hangs', then check out and first test whether the IC Power is still good, do it if warming IC Power is still good, or have it replaced with IC Power IC Power new if it is damaged. After that do the program (flash).
One of the keys when pressed so that the exit is not the same, for example we press the number 5 but the number came out first. We check and test voltage (volts) on the keypad 5, the voltage (volts) that comes out is 2.0 V. damage can be caused by poor connectivity, we do like the way the jumper on top.
One button is pressed causing the phone to die, if we inspect or test voltage (volts) emitted is 2.8 V.
The solution we are doing examinations and tests in advance on the company's IC ¬ Power, Heat Power IC if not damaged or have it replaced with a new Power IC if it is damaged, then do a program (flash) your phone's software.

No Charging Handphone

There is some possibility of damage: Damage occurs in the charging device (charging) battery itself, try your charger on a mobile device that have similar characteristics to identify damaged or not. The battery on your mobile phone can also be damaged so that the battery is not rechargeable. Check whether the connectors on the battery recharging your cell phone is still good. Then we just do inspection and testing of the phone itself.
If on your phone display appears a message "Not Charging" or cell phone refill process (charging), but indicators running without charging rechargeable batteries or refill process (charging) but refill indicator to remain silent so that we can ensure his Charge IC is damaged. Replace with new IC Charge
Mobile phones have been completed rechargeable (battery full), but still refill indicator, then the power IC damaged. Replace with new IC Power
The phone is not in a state rechargeable (charge), but refill indicator, then the software (SW) are damaged. Does the program (flash) on the phone with the same version.
The phone will be made each refill process (charge), hence IC IC Power Charge or damaged. Conduct examination and further testing on the phone to determine whether IC or IC Power Charge and then replace the damaged IC or IC Power Charge damaged.
After recharge (charge) phone with charger, no electrical leakage before power-on button is pressed, when you press the power button-on, the phone is not working. The cause of the problem is electrical leakage in power supply capacity. The goal remains the Power IC, IC UI, which is connected to the input voltage IC VBATT batteryt PA, units that are often damaged and can create problems is the Power IC, IC UI. Because IC Power is BGA, which is an integrated IC, then the method that is usually done is to release IC UI, then recharge (charge) returned the phone, note whether there is electricity kobocoran. If not, then the UI IC is damaged, if any, means IC Power corrupted. The problem is completed, after the replacement IC at the top.
We recharge (charge) the phone, then press the ON button, but the phone did not fire, no electric current into the phone. If so then do measurements on the R224, if the ends do not have the VBAT voltage of 3.2 V, the mean IC Power is damaged or there is poor soldering in the power IC. Replace damaged Power IC or re-soldering the IC Power
Try to flash your phone again

On the phone is mute, if we use the phone, others we can not hear our voice, we can examine and test the components using MIC multitester with the following steps:
Use the manual on multitester xl scale, the positive pole cable connections and cable from the negative pole on foot multitester MIC component, if the needle moves so multitester MIC components in good condition. But if you do not move the needle on multitester then we need to replace the components of the MIC, for MIC of damaged components
Next we test runs of MIC components. To test the MIC kaponen point, we also use the manual on the scale multitester x1, connect the interface cable with MIC multitester on positive and negative poles, the needle moves multitester if, then the good line, but when the needle multitester not move, then the MIC broken line. We can make jumpers syste

MACAM KERUSAKAN KOMPONEN HP

The problem is that the antenna can tedak signal, which causes the antenna connector is improperly installed on the PCB, this usually occurs after Cassing replacement. The antenna is not good condition will cause damage to the IC Section Transmitte PA, with stable performance of the PA to do Transmitte IC continuously because the condition of the antenna connector is improperly installed so that the IC PA to work outside their ability to cause weakness of the PA IC.
 IC RF IC PROCESSORMasalah on Hagar is the loss of signal generated, if done manually on the choice of mobile phone network, but can not detect a single operator. Can also cause death total Phones
 IC PA (power amplifier)
Problems that arise in the IC PA are:
• The number of deaths, because PA Short occur at IC
• Drop the battery during a call
• Lost Signal, No Access, No network.
• Unable to make emergency calls / 112
• Signal exist, but can not make calls

 VCO (Voltage Control oscillator)
The problem arises because of damage to the VCO when the manual is not able to detect all existing Provider, while the second network operator, or detect only one operator only. And also can cause death total in Cell Phones
