How to troubleshoot a dead phone - Lets learn about this

Sorin I have a iPhone 7 plus that's not charging when on.. only when off any idea

Good morning Master Sorin!
I bet the guys just shorted a track +v under the first layer of the pcb with a wrong long screw on those screw holes . Thats a common fault for apple devices.

We must be carefully with the screws when assembling the phone together again.

Hello, thank you for your great videos. We have charging problems with lenovo Tab Model A10-70F roken USB, we have replaced the charging USB port with no problems. worked fine for one day but now tablet charges only when closed and charges too slow. We have checked USB again for broken pins but seems everything is fine, but issue still remains. I would appreciate your advice. Thank you!!!

May i know the software your using?

very important lesson he is explain..... thanks such a amazing person

lot of explanation but less job done 👎

Hello i just wanted to let you know i had a similar problem and from my experience on the uper side lcd connector there are 3 capasitors and on top of them there is a condactive sticker-tape from the manufacture and when you try to connect the lcd to the board fpc with your finger if you dont be carefule you also press that condactive sticker to the 3 capasitors and you get a short. So if you the sticker stops touching the capasitors the short also disappear. Love the videos ! Take care.

thank you mr.sorin im learning . more power

Sir what was the free web site that i can see scamatics

Hi im fairly new to smd repair and i wanted to know how to you diagnose motherboards that not powering on but not reading a short? Example I have a galaxy tab 3 thats not powering on, the battery is okay when i connect the power supply (5v ,2amps) to battery connector on the board im only getting a draw of 140mil amp which keeps fluctuating. I am lost

What's the name of the software, the one with schematics

Sir what the name of your apps you use for schematic

This is an interesting video, found the problem after checking quite a few differing things but now good. Hurrah! your the best SORIN.

How do you protect from static electricity? I see you touching the board with bare hand all the time? Are you connected to the ground?

Just seeing this video and love to contact you. Am from Liberia West Africa. How is it possible?

Static?

I think plastic screws are in order from now on. They were so lucky because they would have gotten their asses kicked.

hey there! Can you tell me what do you use by charging phones to messure if its charging well ?

i really like your videos. you have really upgraded me from beginner to expert. great thanks from Kenya, Nairobi, Africa

hi sir. how do you do tests to tell its lcd itself is faulty or other component is faulty which causing the screen became flickering..? thank you sir.

Thermal imaging camera is best for shorted circuits! Shorts are the best to diagnose. Open circuits are the worst because you can’t see it with a thermal camera.

Tip for iPhone repair. ..... All of the screws are the same length. Once you put them in the board. Let them drop into the hole, if they sink up to the head they are too short. If they stick out more than a mm, they are too long. All screws take as many turns to tighten up. More than three full turns and it is too long.

Hi Sr. Where do you get the diagrams and that image that you show on the video?

You are a best 👌 thanks for making video very helpful 👍 thanks again
