iPad pro 12.9 No Power Tricky Repair - Finding Short Circuit by Voltage Injection & thermal camera

[@rahulmechatronics]

Alex = Encyclopedia of Electronic Repairs... 👍👍👍👍

[@chasefournier]

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.

[@danielgrevan]

Yes, I believe it too because the short is not so "strong" so the coil resistance would absorb the heat.

[@osbertotabor803]

Science people increase the volume 😎

[@andchip.s]

@@baghdadiabdellatif1581 What?

[@evoxslaydiy7620]

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!

[@bjorns7860]

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)

[@davebollinger8863]

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.

[@TECHHUBfixitup]

Only an expert like you Alex,can repair such complicated problem.Very well done.

[@charlesgrant8032]

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. Charles Grant Toledo Ohio. Best Wishes

[@mistwolf]

I really enjoy the insight and methodology you use to find the exact component to replace. :)

[@APKIDUNIYAbyBILAL]

The knowledge you share is priceless! Thanks for the videos!

[@AntonioWengratt]

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!

[@gersonlumapak4783]

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.

[@mrunknown7271]

I like the happiness on face when you fix your job love from India..

[@VideoServicesLI]

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.

[@mohammednabil9792]

When it comes to ipads and iphones I rarely ever see you not finding the fault! Awesome job

[@lukegermishuizen8256]

Good job Alex. Always learn something new. Thank you, and keep up the good work

[@Kaulat123]

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.

[@Hollzer]

Haha, same here 😂

[@aliasgerzakir]

The knowledge you share is priceless! Thanks

[@fernandocastro9362]

Did you replace back the capacitor ?

[@starlight55971]

Super useful to show tracing the actual bad component versus the bait. I would have been focusing on the diode in error.

[@brendonmason5750]

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!

[@nabilseoudi2910]

Another successful repair story, bravo Alex, thanks for sharing.👏🌹

[@fegegita6385]

you're great as always! from "Ethiopia, Africa"

[@CharlieCharlie7310]

Good day Alex, thank you for demonstrating how you use alcohol to point out the shorted component.

[@shafshaf9713]

U r like a teacher for me I Lorne so many things from Ur videos tnx

[@azurequazar3874]

you are the master in this, is such an honor to learn from you!

[@goringbarredo3533]

great job! thermal cam is a priceless tool in electronic repair industry!

[@shastrichandoo817]

Wow! Very good repair video. Voltage injection at the right location certainly makes all the difference. Thanks alot

[@MrPenguin098]

Learn something new in every video. Thank you for making these videos.

[@germanmoreno9551]

Nice process to find the shorted component, thanks for teaching us

[@laivindumalaog8442]

Always amaze by this man there's no broken gadget he can't fix, With a right tool and lot of experience great job sir ♥️♥️

[@TheLebaneseGuy]

Nice work but caused the cap to go bad ?

[@fikrinoh1135]

I have a question. Is it okay to let the capacitor unreplaced with a new one? I mean, there's no caps there after removing it, but does everything works fine even without it?

[@tobiasmangoma9566]

It's gonna work fine. There is optional capacitors to that can take over the functions of the removed one. Redundancy. If one fails then another one can take over

[@maklogetrich2378]

bypass caps, it's okay if you remove one, there's plenty on board

[@Wingedmechanic]

No. It's not. While I agree with others on the bypass redundancy part where the absense of one cap will not cause the device to stop working, you have to understand that the capacitor at that location is there for some purpose. If it's presense or absense doesn't make a difference, manufacturer would have done without it.

[@majkelos8853]

​@@Wingedmechanic They are very important as they acts as a kind of energy reservoir. If the input voltage drops, then a capacitor will be able to provide enough power to an IC to keep the voltage stable. Otherwise, the IC could end up in the unstable state.

[@isahizhenfahm6576]

Great repair. Lots of experience showed.

[@aliefvienna7]

Masta, what is the safe value of voltage and amp for injection?

[@maxop_91]

Nice video to learn from... job well done... as someone said already... the knowledge you share is priceless !

[@empithree]

Does FLIR phone can pinpoint exactly like your thermal cam does?

[@somethingaboutachainsawgam8137]

So much knowledge in the repair field that you're sharing with us all.

[@imbeesh2150]

you should use rosin smoke.

[@muhammadamierrizalkhairudi8855]

I want asking one question master, when we put alcohol to those capacitor. How to know that capacitor you remove is short to ground ?

[@R.AudioElectronics]

Love the thermal cam and the short injector

[@redtec1]

good video alex, you would have tried rosin for technicians who do not have the budget to buy a thermal camera, to see if that type of tool really works, best regards and blessings

[@florinel181]

Thanks for the video , very nice to share your experience with us ! God bless you 🕊

[@zaidtechtips4886]

are you testing display card on motherboard? or you have specific device for testing.

[@jenselstner5527]

Hadn't you have a tripod for the thermal camera in one of your video ?

[@suryavanshib]

Awesome ✌🏻✌🏻✌🏻 When will you fix your thermal camera stand🤔🤔🤔

[@rasheed3039]

Patience is always rewarding 👍🏼

[@pauljatta4777]

U work so confident and I love the technics

[@josearrasola7236]

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 !

[@thomasfretz9684]

What good is the tablet without a working screen

[@donnan9548]

This is awesome video clip. I love it because I've learned from video how to diagnose. Thank you much for sharing.

[@SergioCastiglione1]

E bravo ad alexuccio! Complimenti ! Bel lavoro

[@loopdemack]

Great job. Real fine detective routine. I'm stunned how bad caps apple is using. For regular non-smd capacitors we have different classes, with smd you cant even know the manufacturer.

[@basharhermas1862]

شكرا بكل معنى الكلمه... فكره تتبع المشكله عبقريه

[@christospashalis6684]

Good Job again alex.Thanks for the beautiful videos.

[@alexluz7023]

1:26 it seems theres a broken or rusted pin on the fpc connector

[@AntonioEligius]

Do you exclusively recommend aluminum tape over capton tape? I ask because I notice you only carry aluminum tape in your store.

[@sorehammer]

Once again you show why your one of the best

[@AllCarsLED]

my favorite KZbin channel

[@kharapcapicitor1]

I like your thermal cam great work

[@pierrelago2910]

Great instructional video as always. One question on my side : are you limiting curent when you inject voltage on the board ? And if yes, how do you fix the maximum curent injected ? BR from France.

[@netpackonlinesolutions3254]

Another awesome repair. Thank you master. Very useful tips. It's funny to see you use alcohol to detect the bad component 👍. Greetings from Portugal.

[@stefanlechner]

Very interesting and informative video. So usefull. You are the best alex. Thank you for the video

[@SV6JHV]

No third hand ? why?? Great fix! Thank you for share.

[@TechFromHell]

You fixed it just by removing the cap ?

[@omaribrahim2736]

Yes

[@alupci]

No saving the world from complaints today :). Very informative video!

[@617Pimpin]

Great job as always. Hope the family is well.

[@mm0077]

Third hand, I have heard this before. I am looking for one LOL. Pleasure to watch.

[@tech_jims]

Great video very skilled work 👏🙂

[@axelpgrassi]

I feel you. I do not have a third hand unfortunately either.

[@sleeprestchill]

Insane troubleshooting skills👍

[@johny1220]

“Don’t test boards when they’re hot” got it! Can’t believe that actually makes a difference and causes a short wow lol

[@FIXDIY]

تشخيص جيد للمشكلة ، استمر ✔️

[@faizanaziz7707]

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

[@rockyvlog4087]

Hello always watching and support to your channel....

[@ztssailo]

visual inspection is one of the key to success

[@neutrinowave]

why Alex you don't assume that battery is defected for some reason?

[@ianbunton6396]

Which flir thermal camera do you use?

[@ruksanaaftab3292]

*awesome tip "don't test for shorting on heated board" thankyou sir for this tip*

[@michaelmayfield6968]

Did you replace the item you pulled off? Is the motherboard over engineered to withstand a missing component.

[@starlight55971]

One of his previous videos he used an analogy of 100 officers protecting a building. One calls off sick but the remaining 99 protect it just fine. It's when a lot are missing that there can be an issue.

[@NorthridgeFix]

@Chris You get an A+ for remembering that. kzbin.info/www/bejne/rnexdJVuZtyUj7c

[@shanchya]

Superb chief ..... you make my day .... as always ...

[@yannikcod8257]

Great fix! Very nice technique removing the cap.

Nice find, I had a screen here today like that, so thank you for confirming about the screen.

[@Ender_Recoding]

Amazing work man continue to work like that ^^

[@loadedfry2.089]

Need that voltage injection tools.

[@DAVIDDAVID-85]

Hello sir, excellent work. I want from you the model number of the thermal camera and how much is it in dollars

[@iPhoneScreenFix1]

Best videos are coming from you Alex Thanks for sharing it.

[@azharuddin2023]

Hot cap short! Awesome information

[@badrsabiri]

Thank you for sharing this knowledge with us

[@CLBathory]

Thank you for sharing these videos! So informative!

[@MrHackerDude1]

Would this be the same with a samsung note 9 a problem on the board , because the battery is not connected and it's getting 0.02 then 0.05 on the amp meter or could this be a charging port problem

[@paulabantojimenez5999]

No guts no GLORY... THANKS MAN

[@abdorb6152]

awesome work . thank you for sharing
