In the silent phone, if we use mobile phones, then the other person we could not hear our voices, we can conduct inspections and testing of components using MIC multitester with the following steps:

* Use the manual multitester xl scale, the positive pole cable connections and cable from the negative pole at multitester legs MIC component, if the needle moves so multitester MIC components in good condition. But if the needle does not move multitester we need to replace components of the MIC, for MIC of damaged components
* Then we test the path from the MIC components. To test MIC kaponen lines, we also use manual multitester scale x1, connect the interface cable to the MIC multitester the positive and negative poles, if the needle moves multitester, so good point, but if the needle does not move multitester, the MIC break point. We could do jumpers system to cope
* If a good path, try to heat the IC Audio by using blowers
* If the phone is still silent, replace the IC with the new audio.
* After we did the hardware but the phone was still silent, then there kernsakan program (software) phone.

wasteful batteries

We see from the durability (life time) and standby time and talk time, we can examine and test the phone by using the power supply with the following steps:

* When your phone is still in a state of death (off) this is the current mobile phones have taken on the battery, the needle was evidenced by the power supply amperage showed 100 milli amperes. Things like this that caused the phone battery wasteful, because the phone constantly taking the flow of mobile phone battery is dead though.
* Now remove the first IC PA.
* Perform a retest again as above, see if the needle amperes silent, then surely the PA IC is faulty.
* Replace IC PA with a new, re-do re-test as above, see the needle amperes, ampere needle must remain silent.
* Battery you are not wasteful anymore.

Unstable signal Problem: The signal on the phone is not stable, sometimes strong, sometimes weak.

Repair procedures:

* Check whether the phone can be used to search the network manually. If the phone can not find the network manually, the RF IC (HAGAR) damaged, replace the RF IC (HAGAR).
* Also check whether the path to the PA IC was not broken.
* If the phone on the other hand can find the network manually, the PA IC damaged, replace the IC PA.
* After the hardware of the phone has been tested and improved, but problems still arise, we need to reprogram / flash the phone software re-fit the type and version of your phone or with a newer version than the previous phone software version.
* Turn on your phone, then your phone will work with kemb nor ¬ mal
