P.F.O. (Power Frequency Oscillator):
👉 P.F.O. Identification on Mobile Phone PCB:
PFO IC mobile phone ki PCB board per network section me lagi hoti hai. PFO antenna switch or network IC ke aas-pas laga hota hai. Iske pas ek network capacitor laga rahta hai. Jo 2 se bhi adhik non electrolytic capacitor se bana hota hai. Ise P.A. (Power Amplifier), Power Filter Oscillator or B.P.S. (Band Pass Filter) bhi kahte hai. PFO PCB board per sabse upper laga rahta hai. Yah aayat ke shape ka hota hai.
👉 P.F.O. Works:
Yah Network frequency (signal) ko filter or amplify krta hai.👉 P.F.O. Faults:
PFO ke faulty hone per mobile phone ye faults aati hai –
1. Network not working
2. Network nahi aana
3. Weak network signal
4. Network Signal aana or jana
5. Battery low back up
6. Network related others faults
7. Short Mobile PCB board
8. Dead Mobile Phone
Ab aap pfo ko mobile phone pcb circuit board per easily identify kar skte hai. Mobile phone repairing course online free in Hindi ko apne workless friends ke sath share kare. Aapke ek 2 seconds ke work se kisi ki life ban skti hai.
