Thank you for sharing!! I do not have any experience with board repair yet but am starting to learn :)
My only reverse tip for you guys is to clean the camera lenses when reassembling, since after the back cover goes on, the user can not do it. I usually make them dirty by accident haha!!
thanks again!!
Great video
Congrats
Nice clear video.i always love you chanel
Thank you!

Top markotop bos
U are amazing
Great job, just wondering how he made the first conclusion that the main power IC was not working and from then on how did he know that the clock oscillator was not working?
I'm not sure somebody can correct me but i think he tried all possible places this problem could be coming from and then he left with this two things so he went for it , i don't think you can check them for sure
He could've checked for VPH at the power switch line and assumed VPH is ok and good and concluded it to be a problem with the PMIC .
Great job ! But I can't see well where you put mesurment instruments on d board ! Maybe you can approch near thé camera for better insight ! Thanks and verry good job !
Thank you great work do you do Tecno
Nice job sir, how can we get the components for repair
Thx sir
جزاك الله

thank you for a very educational video about android phone repair! But a verizon samsung phone in China? I guess it must be from a tourist. I also carry a verizon phone when I go abroad because it's completely network unlocked.
Good job
Great!
Good video
Love You Brother India Kolkata 😀😀😀Whare Is Your Shop ...
As a result the ships resposible for no current problem are :
1- Main Power Ic
2- The oscilator
Only these two ships sir engineer?
Good 👍
love you sir
=====(￣▽￣*)
Thanks
Thanks...
2 questions since im new at this dont judge
What did you use the multimeter to test?
Couldnt the dc powersupply be used to basically do the same thing as the multimeter?
Power managemen unit IC is bad, but first of all, allways need to check crack condensator, varistor, temperature sensor. Vbat, Vsens, V_core, V_reg, rtc frequency, V_sim, thats value need to check before change pmu, need to use osciloscope
Nice information great sir god bless you
thanks cino
Nice work
Thank you!
If I were you first I wouldhave changed the crystal...any way good job
The crystal should be replaced in the first place.
GOOD SIR
Nice
Thanks for interesting video. What did you start testing at 2:47? Resistance to check that resistors are not shorted? ( You say TEST THE CURRENT... so I was a little unsure :-)
Power Supply ICs
@@CINOTechnology I know you check Power Supply IC function but HOW do you test? By measuring of what? Resistance - if resistors are not shorted? Thanks
@@ladbla1752 no bro, he is checking surrounding components like coils and caps using 'diode mode test' method
Best
Would like to see repairs if possible and if you have time on Samsung phone, as this are the most purchased in the USA, thank you.
thank you so much very helpful video, where can I buy ICs and other small pcb components?
Power Boot Failed because of sleepclock Oscillator 32.768KHz ... ;) , GoodJob
Allah razı olsun
eres buena gente dios te bendiga
tu buen amigo
Where do you get all those components? Do you know what's the role of the oscillator here, frequency adjustment? Is there a schematic? Nice fix!
Shenzhen,China has anything you want for machine repair.
Nice cino
awesome👍👍👍
Thank you!
Good

bravo
Sir i have a A70s , it wont turn on , wat to do , how can i send my phone to you for repair.
Learn from this video is to replace the smaller parts then the major parts
Yes
hi nice video. by the way, i found a lot of samsung dead, and current consumption after power On is around 0.3~0.4A , and stay there, not boot up. The CPU is very hot, i dont know if there is short in CPU or because cpu was trying to boot up repeatedly. Can you give me advice ?
Power supply short circuit, especially the outer parts such as camera power supply.
In this process, internal storage data will be lost? Or it will keep as it is before
If i had your equipment it would make my work more easier😥
Hey, such a wonderful job! Anw i have a problem with my poco f1 phone that boot up but won't on, what cause such issue?
After checking the external configuration, it may be that the power-on circuit of the motherboard is faulty.
@@CINOTechnology Thank you so much mate, really apreciate it!😍
Nice job boss.
Please, kindly drop address the ic and crystal oscillator can be bought from online.
From Nigeria.
cinomall.com maybe ，You can also get it by buying a discarded motherboard of the same model
Can you make a video for the Umidigi A7 Pro?
The main thing I can ask him I need that soldering pest where they sale❤❤
What tool is that with those small claps?from that you get current(220v)?
Well done but I need to lind more
Thanks for your support
how did you know to check the crystal oscillator?
That's the work experience bro
Cino tech please am begging for an intensive video on the components found on a mobile phone motherboard and their function
i think motherboard repair will be easier for me if I can easily identify the components on the motherboard without guessing which one is which
Our maintenance tutorial is in the works, it will describe more systematic and detailed
@@CINOTechnology Thank you Cino tech i remain grateful
So it's possible to fix the motherboard and avoiding lost of files. Because I ask so many technician in my country and all of them are suggesting to replace the motherboard
Hi there, I have no reading for the power button circuit. I got OL when testing the power button. Can you tell me what might be the problem?

Hello ..my a50 microphone is malfunctiong..I am not getting heard at the other side..have replaced microphone flex also still not working ..is it a motherboard issue? Thanks
Cannot hear the other side? It seems the ear speaker has been faulty. Replace the ear speaker. If still not working, then audio IC might have been faulty., check this: ua-cam.com/video/cRVhK-5cPQY/v-deo.html
Hi it is ok not to put back the cover shield..cos mine is damage thank you for the answer
That works.
smart
Hi master!!!Great job!!i have the same problem, can you tell me the specs of the smd 32.768 oscillator please? Thank you,good work

Don't get me wrong please I said so because she worked for me and it excellent.
love it
