I think there should be phone engineering course in our schools... You would be a great teacher if it were to be a school. Love it
@@odemechigozie thanks buddy
pure gold... we can't thank you enough for what you are doing for the industry
@@godlistenanthony 😊
You are one in thousand and very rare to find. I really love this video too much.
I realized that, the hardware solution couldn't work but upon applying the schematic diagram, the problem got solved.
I'll entreat every one to become a member of this channel so that you'll enjoy more premium lectures because this man, Prince Arora is the best mentors I've ever found.
May God bless your work and your kind heart for such knowledge.
I LOVE YOU MASTER ❤

Learn a lot from this video Master Prince Arora, the value of ic counting, schematics , measureing , much of the courses you have already given are manifasted in this video! about video qualities not need to wory at all this is just a live practical diagnosis not a movie, what really matters is the idea of how to diagnosis and ofcourse it is a good video as a bigner for live diagnosis and considering you are a camera man , a diagnosist, and editor and general manger of this great movie, and as you are now making Best video of lecture courses, hope better videos of live diagnosis will also come through time ! for now thank you very mush sir!

Nice 👍
@@ameerkhan8272 👍😊❤️
Glad the repair wasn't direct, that part when the ic was changed and still we were still at square 1; gave us a chance of getting into the insight of your experience to showcase us how to think as technicians. Loved the process, the diagnosis, the solution💪
Thanks buddy 😊😊
Good job❤❤❤
@@jayrophi5242 thanks buddy 😊🙏
hi. thanks for video. i do not understand where you get the values from. Is this diode voltage drop settings ?
@@anno32 experience
Please make a short video about duplexer, couplar all small things in network section Please
@@ousmanezoumanaouattara97 okay
This one is quite experiential but you were mentioning diod value of 438, 439 and getting the same value on the motherboard, were you getting it from the schematic?
@@jeromeede7440 because My multimeter connected with pc it's lagging in half second.i am looking the multimeter not the pc screen
Yes in boreno therese a schemati diagram with diode values he did not show it on the screen
And also most phones have around same values for certain lines with experience you will spot the faulty line because it is going to be different from the lines that it should have the same value as them for example some lines should have same diod value and they rarely be cut all at once so you will see the abnormal diod value of that line based ln the working lines and also there is schematics with diode values in borneo schematics
Sir can you show us the ppd that u are using by picture ?
@@augustinondunguru1609 kaisi 183
Time 37:00 Where to type BAR for component values ? I try on Component, I try on Schematics , nothing appear!
Time 30:24 Why A2 OutPut is OL, any output line is OL or? A bit explain for this...
@@Sherifone78 Whatever scrap board or donor board do you have? Open the schematics of that model in Borneo. In the search bar, type the value of the component you want, and click next you will get the location of that component, where is it in the scrap board
