Big Parts of a Mobile Cell Phone and Their Function: Antenna Switch: It is found in the Network Section of a mobile phone Cell Phone Antenna Switch and is made up of metal and non-metal. In GSM sets it is found in white color and in CDMA sets it is found in golden metal. Work: It searches network and passes forward after tuning. Faults: If the Antenna Switch is faulty then there will be no network in the mobile phone. P.F.O: It is found near the Antenna Switch in the Network Section of the Cell Phone PFO PCB of Mobile Phone. It is also called P.A (Power Amplifier) and Band Pass Filter. Work: It filters and amplifies network frequency and selects the home network.   Faults: If the PFO is faulty then there will be no network in the mobile phone. If it gets short then the mobile phone will get dead. RF IC / Hagar / Network IC: This electronic component found near Cell Phone Network IC / RF IC the PFO in the Network Section of a Mobile Phone. It is also called RF signal processor. Work: It works as transmitter and receiver of audio and radio waves according to the instruction from the CPU. Faults: If the RF IC is faulty then there will be problem with network in the mobile phone. Sometimes the mobile phone can even get dead. 26 MHz Crystal Oscillator: It is found near the PFO in the Network Mobile Phone 26 MHz Crystal Oscillator Section of a Mobile Phone. It is also called Network Crystal. It is made up of metal. Work: It creates frequency during outgoing calls. Faults: If this crystal is faulty then there will be no outgoing call and no network in the mobile phone. VCO: It is found near the Network IC in the Network Section of a Mobile Mobile Phone VCO Phone. Work: It sends time, date and voltage to the RF IC / Hager and the CPU. It also creates frequency after taking command from the CPU. Faults: If it is faulty then there will be no network in the mobile phone and it will display “Call End” or “Call Failed”. RX Filter: It is found in the Network Section of a Mobile Phone. Mobile Phone RX Filter Work: It filters frequency during incoming calls. Faults: If it is faulty then there will network problem during incoming calls. TX Filter: It is found in the Network Section of a Mobile Phone. Mobile Phone TX Filter Work: It filters frequency during outgoing calls. Faults: If it is faulty then there will network problem during outgoing calls. ROM: It is found in the Power Section of a Mobile Phone. Mobile Phone ROM Work: It loads current operating program in a Mobile Phone. Faults: If ROM is faulty then there will software problem in the mobile phone and the set will get dead. RAM: It is found in the Power Section of a Mobile Phone. Mobile Phone RAM Work: It sends and receives commands of the operating program in a mobile phone. Faults: If RAM is faulty then there will be software problem in the mobile phone and it will get frequently get hanged and the set can even get dead. Flash IC: It is found in the Power Section of a Mobile Phone. It is also Cell Phone Flash IC called EEPROM IC, Memory IC, RAM IC and ROM IC. Work: Software of the mobile phone is installed in the Flash IC. Faults: If Flash IC is faulty then the mobile phone will not work properly and it can even get dead. Power IC: It is found in the Power Section of a Mobile Phone. There are Cell Phone Power IC many small components mainly capacitor around this IC. RTC is near the Power IC. Work: It takes power from the battery and supplies to all other parts of a mobile phone.   Faults: If Power IC is faulty then the set will get dead. Charging IC: It is found in the Power Section near R22. Cell Phone Charging IC Work: It takes current from the charger and charges the battery. Faults: If Charging IC is faulty then the set will not get charged. If the Charging IC is short then the set will get dead. RTC (Simple Silicon Crystal): It is Real Time Clock and is found in Mobile Phone RTC (Real Time Clock) the Power Section near Power IC. It is made up of either metal or non-metal. It is of long shape. Work: It helps to run the date and time in a mobile phone. Faults: If RTC is faulty then there will be no date or time in the mobile phone and the set can even get dead. CPU: It is found in the Power Section. It is also called MAD IC, RAP IC Cell Phone CPU and UPP. It is the largest IC on the PCB of a Mobile Phone and it looks different from all other ICs. Work: It controls all sections of a mobile phone. Faults: If CPU is faulty then the mobile phone will get dead. Logic IC / UI IC: It is found in any section of a mobile phone. It has 20 Cell Phone Logic IC pins or legs. It is also called UI IC and Interface IC. Work: It controls Ringer, Vibrator and LED of a mobile phone. Faults: If Logic IC / UI IC is faulty then Ringer, Vibrator and LED of mobile phone will nor work properly. Audio IC: It is found in Power Section of a mobile phone. It is also Cell Phone Audio IC called Cobba IC and Melody IC. Work: It controls Speaker and Microphone of a mobile phone. Faults: If Audio IC is faulty then Speaker and Microphone of a mobile phone will not work and the set can even get dead
