Alex = Encyclopedia of Electronic Repairs... 👍👍👍👍
One of the trickiest things for me in those repairs is to know where to inject voltage. That's why you need experience. The thermal camera is a K9 but you need and one trained officer to complete the job. Well done!
I'm guessing the reason why injecting voltage before or after the coil makes it difference is because the coil can take the load. Very informative video Thank you so much.
A coil is basically a very thin wire, and the part that gets hot is always the component with the highest resistance. So if the short on the capacitor is really low resistance, the coil might be higher resistance and thus taking most of the power that is being injected. Injecting after the coil means the coil is no longer part of the circuit and the component with highest resistance is now the shorted cap
Yes, I believe it too because the short is not so "strong" so the coil resistance would absorb the heat.
Science people increase the volume 😎
@@baghdadiabdellatif1581 What?
I really enjoy watching your videos and it inspires me. I've been doing easy repairs since I was 12 years old but now that I'm 18 I was looking for something challenging and came across this channel. I went to your first video and have now seen all your videos which has inspired me to be able to do this too. so I'm now waiting for my stuff to be delivered so I can practice it too. I guess I'm not the only one and want to thank you for that.
Sincerely, Bjorn Schelfhorst
(sorry, but my english is not my best)
My wife asks me why I watch your videos when I'm never going to do electronics repairs (I'm in IT, BTW). I just find your videos very interesting.
Haha, same here 😂
Only an expert like you Alex,can repair such complicated problem.Very well done.
The knowledge you share is priceless! Thanks
The knowledge you share is priceless! Thanks for the videos!
I like the happiness on face when you fix your job love from India..
Good job Alex. Always learn something new. Thank you, and keep up the good work
Great fix! Very nice technique removing the cap.
Great job as always. Hope the family is well.
Great repair. Lots of experience showed.
Another successful repair story, bravo Alex, thanks for sharing.👏🌹
Thanks for all what you doing to teaching people.💐
U work so confident and I love the technics
I do not work on phones and tablets... but this type of high temp solder is showing up in Audio equipment now too. Thanks to you I am better equipped to repair multilayer boards properly. Have had much better success since following your videos. Thank you.
Another great lesson using voltage injection and a thermal cam. Thank you showing the how, what & why. Always learning. Grateful for you sharing your experience.
When it comes to ipads and iphones I rarely ever see you not finding the fault! Awesome job
you're great as always! from "Ethiopia, Africa"
great job! thermal cam is a priceless tool in electronic repair industry!
I really enjoy the insight and methodology you use to find the exact component to replace. :)
So much knowledge in the repair field that you're sharing with us all.
Thanks for the video , very nice to share your experience with us ! God bless you 🕊
Good day Alex, thank you for demonstrating how you use alcohol to point out the shorted component.
Nice process to find the shorted component, thanks for teaching us
Thank you for sharing these videos! So informative!
“Don’t test boards when they’re hot” got it! Can’t believe that actually makes a difference and causes a short wow lol
Amazing work Alex 👍🏼 God bless
Just bought one of the voltage injection tools from your site a few days ago. Can't wait to start using it. Thanks for the great videos and knowledge. Keep up the good work!
Love the thermal cam and the short injector
E bravo ad alexuccio! Complimenti ! Bel lavoro
Patience is always rewarding 👍🏼
you are the master in this, is such an honor to learn from you!
شكرا بكل معنى الكلمه... فكره تتبع المشكله عبقريه
Really thanks for sharing your knowledge
Learn something new in every video. Thank you for making these videos.
Nice find, I had a screen here today like that, so thank you for confirming about the screen.
Super useful to show tracing the actual bad component versus the bait. I would have been focusing on the diode in error.
Amazing work mate, you are indeed 'Da man'
Nice video to learn from... job well done... as someone said already... the knowledge you share is priceless !
awesome!!! finding a short is very hard but you find it very easy with the right tools hope i have the right tools for my job. thank you for sharing sir.
Nice work sir , it’s always awesome to see you work and how you find different ways for no touch and no power sometimes they could be coming from the same place !
This is awesome video clip. I love it because I've learned from video how to diagnose. Thank you much for sharing.
Good job alex you have done a great job. You are my inspiration. i have learn a lot of things from you thank you..GOD bless you
Always learning something new
Wow! Very good repair video. Voltage injection at the right location certainly makes all the difference. Thanks alot
An awesome fix. Your videos are interesting and great. Thanks a lot.😍
Once again you show why your one of the best
Insane troubleshooting skills👍
Very interesting and informative video. So usefull. You are the best alex.
Thank you for the video
Good Job again alex.Thanks for the beautiful videos.
I like your thermal cam great work
Brilliant fix, always new things to learn
U r like a teacher for me I Lorne so many things from Ur videos tnx
Nice one. I really did not know about testing a hot board can still show shorts, and also, did not know about the coil. I'll surely use this on my diagnosis from now on. Thank you, man!
Best videos are coming from you Alex Thanks for sharing it.
awesome work . thank you for sharing
Wow. Thanks for the repair
Yes, awesome repair!
I just want to say thank you. I have always been interested in soldering for just a hobby. Ive always done wires and such for my ham radio hobby. I recently broke one of my radios antenna connector by dropping the radio on the ground. I was mad and excited at the same time as this was my first attempt at a "real" repair. I orderd some amtech 559 and solder wick to use with my weller we1010na from you guys. I ordered the replacment part and began my repair, unfortunatley i was unable to repair the device and broke the board. This did discourage me at first but i have since then ordered a few practice kits for learning to solder and i have told myself to not give up. Thank you for these videos because someone like me with no experience with electronic repair can watch them and get the confidence they need to pick the iron up.
I have learned since then that a hot air station would have worked better for the repair i was attempting.
