How do we know the resitance value of 2 resistors R1 and R2 on sub board of 125f? the resistance is not indicated on the schematic?
@phoneschematicseducation 2 күн бұрын
First you can measure it by keeping the multimeter in ohm mode, what is the value of resistance, how many ohms is it. Second, if you do not have the schematic of that model, then open another schematic related to the power IC fitted in it and trace the line. You will find the power IC fitted in some schematic, the value of resistance of R1 and R2

Good learning video. Quick question do we have any method to identify these lines without schematic diagram.
@phoneschematicseducation 2 күн бұрын
Suppose there are some components installed in a line, their location can be found only from schematics. I don't know of any other method. Yes, you can do it slowly with experience and if you don't have the schematics of a particular phone, then you can repair it with the help of the number of power IC and CPU installed in the phone.

please tell me why any microcircuit like sound, wifi, network needs not only vph but also low voltage 2.8, 2.6 and so on
@saved0ff 7 күн бұрын
or in other words, why does it need 2 power supplies? why not only vph?
@phoneschematicseducation 7 күн бұрын
In answer to your question, I will explain with an example, suppose there is a Wi-Fi, this Wi-Fi requires VPH voltage which is its main voltage on which it works, if we give it only this VPH voltage, then how will the user turn it on and off, because VPH voltage always remains, direct from battery also charger so always voltage. Therefore, it is given a different enable voltage 1.8 which is linked to the CPU, when the user activates Wi-Fi, the CPU turns on the enable signal and the Wi-Fi IC gets detected, now it has to start working

Hi good stuff. I believe when the battry connects, there will be an issue on the battry id line. Once power button press that's why it does not generate the buck voltages. Once connect the charger vbus line will activate and power ic generates the buck voltages. Once usb connects the charging symbol has to show on display. So phone has to do some work I mean for example power shoud go to display, cpu has to do some calculation to show precentage, ram should founction, for that reson every componets should recive the voltages that is why when connect charger buck voltages will generate.

Very informative tutorials. Learnt lots of things by watching your video series. To answer the question, there might be short in battery line means short between battery connector and charging ic or line disconnection between battery pin and charging ic or battery id line issue. fails to create divider circuit. Once the battery connect, battery id line should get 0.9v. If not getting the 0.9v CPU not detect the battery connected. So buck voltages will not generate. Once charger connects cc1 / cc2 lines will activate with charging ic, CPU reads the info through sdlc and sdac then vph generates through the vbus line,power ic enables the buck voltages.
