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
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 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!!
this man is a Professional, great work, your the Best dude, we hope that you uploaded more interesting videos like this,million thumbs upp👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
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?
Hello friends I would like to congratulate you for your work on that motherboards and wish I could have some electronic technicians like you here in Marseille I have a blackberry keyone bronze edition that really important to me unfortunately it overheat during charging and when charging done it over heat also The motherboard is faulty it should be fixable by you guys I'm sure Wish we had more skilled people in France
So it means when current is not getting thru, I have to consider the crystal oscillator first since it is the main component that boots up the current?
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 :-)
@@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
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.
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 ?
Super detailed vedio ..even my A50s got drenched in rain and its not switching on..can I repair mine ...I am in Karad Maharashtra...plz help ...I tried the near by shops ...
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
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: ruclips.net/video/cRVhK-5cPQY/видео.html
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
Sir, my samsung note 9 has a problem, sometimes it can power on sometimes it can't, but if it can power on the phone start to get very hot in a few minute and turn off, now my phone can't turn on, so what is the problem sir, does the power ic make this problem sir?

I bought galaxy a50 about a year ago for 20k..on 23 oct my phone got hung while playing RUclips and after a few seconds it switched off automatically .I went to samsung care, initially they told me that it was a minor software issu but after inspection they told me to replace the mother board for 9000 rs. Now galaxy A50 cost 14k and the cost of service is 9000. Totally lost my mind and I am never gonna buy samsung product in my life. Before galaxy A50 I was using redmi note 3 for around 3 years and got a replacement of rs. 2800in flipkart. Buying samsung was my worst decision ever.
I tried contacting you and sent you email for my Samsung A30 not powering up and how you can help fixing; but no reply so far at all after more than a week !

Hello motherboard of my motorola e4 phone has break down and display screen also not gettig on... is there any chance of repair my phone so i can get my all data back ? Pls suggest me if there any possibility
I have similar problem with my Samsung A50 too, it wont charge first, we change the charger port it goes well for the meantime but kt black out and it wont turn on. What should be the best thing to do with this. Please help. This phone is so important to me.
Hi does it remove all the data in my phone if i get my old motherboard replaced with a new one or is there a way to replace it but not delete all the data in my phone?
You have to resolder the internal memory onto the new motherboard to keep your data. And if done incorrectly you can damage the chip and lose all data.
Hello sir! My samsung A50 wont turn on. I tried the force restart, still nothing happens. I also tried connecting it to a power source, still nothing happens. Do you think that the motherboard is the reason why it remains unresponsive? Too bad I can't bring it to a repair center due to the pandemic and lockdown. What am I supposed to do, I don't have any equipment to fix this. ☹️ Online classes will resume in a couple of months now, and I don't have anything to use.
Thank you sir! But is it okay if I ask you to teach me how to do that? A guide or step by step maybe? 😅 I mean, I'm really not that knowledgeable when it comes to this thing. I would really really appreciate it sir! Thank you in advance!
I don't really know the reason why it happened. My phone was out of battery that day, and I thought leaving it drained will not affect my phone. But I was wrong, I honestly didn't know what happened, I charged it hoping that it would turn on, sadly it didn't.

Hi, I'm from China, I saw your content, thanks for your videos, I learned a lot. Thank you and I congratulate you.
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 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!!
As a result the ships resposible for no current problem are :
1- Main Power Ic
2- The oscilator
Only these two ships sir engineer?

Power supply short circuit, especially the outer parts such as camera power supply.
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
Well done, good jobs, thank you so much, featuring explanation 💯/💯
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!

你好 你在2:01量测值为1.371 我的A50量测值为0.639 你在2:03量测值为2.885 我的A50量测值为OL 请教这会是哪里故障呢? 另外 我的A50有在没接电池的状态下充电 请问这是否会毁损主板呢?
OL就是太低了无法显示的意思，这个脚位有问题。排查这条线路。没接电池充电，直接夹电吗？控制好电压就不会损伤主板。
Sir, my samsung note 9 has a problem, sometimes it can power on sometimes it can't, but if it can power on the phone start to get very hot in a few minute and turn off, now my phone can't turn on, so what is the problem sir, does the power ic make this problem sir?
Both the PM IC and charging IC can cause the issue. Try to replace them in the first place.

flash would be fine
Nope cpu recalling needed there it's a very dangerous issue because samsung service centre also cannot repair it
After installing a new power ic does it require a new firmware
Is there anything on board that can be replaced when it does not detect sim card installed?

Yes
