Sir, Your videos are really very imformative and easy to understand. Thanks for making such a great videos. Would request you to make video for explaination of remaining lines also.

[@phoneschematicseducation]

Oky

[@rizwanshaa]

Perfect sir. I have a query. We need practical with a dead phone ,to apply the schematic way. ❤❤❤❤

[@phoneschematicseducation]

Sure.As soon as possible

[@takecare1764]

More video update sir🎉

[@phoneschematicseducation]

Already uploaded

[@tinsaie_tirufat]

Hey bro. i appreciate what you have done for free. 10Q for all

[@phoneschematicseducation]

It's my pleasure

[@StoryFBMizostory]

i have dead phone pm660&pm660l, voltage on coils are unstable i rewatch boot sequence video here, there is no guide for my issue, i couldnt figure it out, can you make part 3 in future also dc reading guide, if possible, thank you

[@phoneschematicseducation]

If Buck voltage is unstable.. check the secondary line Shorting. near pm ic capacitor check one by one.check buck coil for shorting.also if drop down case some time cpu balls attached so sam condition buck unstable.Pm ic faulty then also Buck unstable

[@sunshineemagbor7549]

Wow.... This is powerful sir.... God bless you sir

[@phoneschematicseducation]

Thanks buddy 😊

[@jaswinderSingh-yt5bf]

Knowledgeable video 🙏

[@phoneschematicseducation]

Glad you liked it

[@chandraKusum-jv6tt]

Great video, help us on the boot sequence of the phone

[@phoneschematicseducation]

💯 wait for some time brother.every person demand defferent topic..

[@MaheshIndunil-zt6js]

Good learning video. Quick question do we have any method to identify these lines without schematic diagram.

[@phoneschematicseducation]

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.

[@MaheshIndunil-zt6js]

@@phoneschematicseducation Thank you for the insights

[@samsongithinji1631]

So this means if i dont have schematic diagrams i just look for vphline,reset?

[@vijaychari6042]

Thank you so much sir

[@phoneschematicseducation]

All the best

[@Appsbiotic]

Brother, if i may ask , can you change to big cursor or color or highlight pointing. White small cursor on white backgeound ( schematic), dizzy trying to learn😅

[@phoneschematicseducation]

Got it

[@kareemazeez618]

Pls sir can you show me how to know the fault of a dead phone using power supply dc.

[@phoneschematicseducation]

💯 upload soon.wait for some time also working on live repair study cases

[@saved0ff]

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]

or in other words, why does it need 2 power supplies? why not only vph?

[@phoneschematicseducation]

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

[@saved0ff]

Understood

[@dn.mobile----]

Sir need full gr coding

[@phoneschematicseducation]

Will upload soon

[@shaad2841]

Are you from India?

[@phoneschematicseducation]

Yes
