Problems or trouble commonly found on phones such as :
-Software
-Hardware
-Software plus Hardware
Android - Blackberry problems and solutions :
1. Total dead phone
Phone total death there are 3 kinds, namely the total death due to :
· total death due to die himself.
Phone total death there are 3 kinds, namely the total death due to :
· total death due to die himself.
· total death due to falls.
· total death due to exposure to water.
· total death due to exposure to water.
- Total death due to die himself.
Ways of handling :
-Remove the battery and insert it again or try using another battery and try to power.
-Check the battery connector and try to press to see the flexure or not, replace a new one if damaged.
-Charging plug on the phone, when the indicator on the phone in and still will not turn on, then obviously you can not live phone due to interference from IC PA (Power Amplifier). After the 'IC PA' unplugged your phone can be turned on again. And so there is a signal it must be installed 'IC PA' new.
-When the tide there is no charging indicator on the switch and the phone still does not want to live it needs further testing using power supply. But there may also have an ugly tin on the PCB, the solution pull 'IC PA', lalubersihkan tin on the PCB where the 'IC PA' stuck, replace the 'IC PA' a long time, turn on the phone, definitely flame.
Examination using power supply :
Required power supply with a scale of 1 ampere ampere (A) or 1000 mA, objective that the examination can be more easily and clearly.
The steps are as follows :
-Plug the cable connector from the power supply to the cell phone battery, a total of at least three cables, the sequence negative , 'BSI' and positive. (black, green and red)
-Navigate volt power supply at 3.6 V (or appropriate cell phone with a tolerance of 0.5 V)
-Phone is off, then press the button On.
-When the current (amperage) on the digital ampere pointer dipower supply when pressed on the button, nothing means that there are problems in the hardware (HW), it needs to be checked from the components on / off until the battery.
-If the amperage when the button is pressed on, up about 50 mA, then the problem is happening is the software (SW), then you need to do is re-programmed HP (flash) or program be upgraded to higher versions.
- Total death due to falls.
Ways of handling :
-Mobile phones should not be tested by using a power supply, but must first be dismantled, heated, and justified re-location / position of the components that change as a result of the phone is dropped / smashed.
-After that the new HP should be tested using the power supply to determine the damage to the Hardware (HW) / Software (SW).
-Most likely, components damaged as a result of a fall last phone was 'IC PA' / IC Power.
- Total death due to exposure water.
Ways of handling :
-For phones that hit the water, the first time should not be tested by using a power supply, because the risk of a short circuit occurs between the components in water, but the phone must first be heated, or use a blower with the first, and given cleaning fluid 'IPA', can also be using silica grains to absorb the water present on the phone.
-Once the phone certainly has been quite dry, then we can use the power supply to determine the damage to the Hardware (HW) or software (SW).
-On the phone due to exposure water, usually there is damage to the cell phone accessories.

2. the total death due to 'UI IC'.
On the issue of mobile phones such as this it is necessary to test the tools 'power supply'.
The steps are as follows:
- Connect the power supply on the phone, give the voltage (volts) of 3.6 V (or appropriate cell phone with a tolerance of 0.5 V)
- When the phone is off, look at the needle ampere power supply will increase by 100mA.
- Mobile phones to life, LED lights, vibrating.
handling:
- Remove the 'UI IC', then turn on the phone.
- Then there is the LCD display on the phone "Insert SIM Card".
- Install a new UI IC.
- Turn on the phone, the phone will work fine.

- Install a new UI IC.
- Turn on the phone, the phone will work fine.
3. Phone off the total as 'CPU IC'.To find out whether the phone off the total for 'CPU IC' is as follows:
- Give the voltage (volts) on the phone by using the power supply of 3.6 V (or its corresponding Hp with a tolerance of 0.5 V).
- When the phone is not turned on, the needle ampere silent, but when the phone is switched on then the needle will naik100mA amperes.
- Give the voltage (volts) on the phone by using the power supply of 3.6 V (or its corresponding Hp with a tolerance of 0.5 V).
- When the phone is not turned on, the needle ampere silent, but when the phone is switched on then the needle will naik100mA amperes.
Ways of handling :
- If 'CPU IC' is still in good condition, then we only need to heat 'CPU IC' by using the blower ( rehot ), but if the CPU IC is damaged, then we need to replace with a new CPU IC. Before we replace the CPU IC we first have to have the glue is heat resistant and heat resistant glue liquid destroyer, for 'CPU IC' is protected by a heat-resistant glue, after we destroy the heat-resistant glue, then we can heat (blower) to replace the CPU IC new. Similarly, after we replace 'CPU IC' with a new one then we need to give more heat-resistant glue to protect the 'CPU IC' which we just replace it.
4. Total dead cell phone during a call.
To do the testing we use the power supply, how :
- Connect the phone with the power supply, let the voltage (volts) of 3.6 V (or its corresponding Hp with a tolerance of 0.5 V) padaponsel.
- Ampere needle will not move when the phone is still dead.
- We turn on the phone and then used to make calls, then the needle will show the number above ampere 400mA.
handling:
- Replace with a new PA IC, after re-testing was done as above, if the needle of the ampere test results showed readings below 400mA, the phone is in good condition.
- Connect the phone with the power supply, let the voltage (volts) of 3.6 V (or its corresponding Hp with a tolerance of 0.5 V) padaponsel.
