Hi, I'm from China, I saw your content, thanks for your videos, I learned a lot. Thank you and I congratulate you.

[@paulmendes9315]

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?

[@omarlakhdari5186]

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

[@freakbot1056]

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 .

[@abraakpla993]

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 !

[@TheKoodus]

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!!

[@KarimLikes2Play]

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

[@mrgsm2003]

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 ?

[@CINOTechnology]

Power supply short circuit, especially the outer parts such as camera power supply.

[@bozorenic9561]

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

I bought galaxy a50 about a year ago for 20k..on 23 oct my phone got hung while playing KZbin 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.

iPhone is a better choice

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?

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

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.
