It's easy to get tempted to do it. I have to admit, if I didn't already have a board with the slave PMIC removed I might have fallen in to to trap simply to find where that testpad was going.
Certainly when all else has failed and you start resorting to slightly-random part pulling it's probably already time to walk away from the job ( unless you're dealing with something like a liquid damage area and you're hunting for a part with a dud pad etc )
Cost factors. Not sure about the overhead though, that's a SONY AX33 and usually does a fine job in keeping focus, face cam is a Panasonic HVX1, likewise usualy is fine, but the microscope camera is something that I'm needing to change as I've never been entirely happy with it; limited DoF and poor light sensitivity ( so you can see the correlation there ). Also need a larger dedicated monitor-screen for the OBS output as my eyes shift a little too much during the course of the day, subsequently even when the eyepieces are set in morning I've already drifted by middle of the day etc. All work in progress.

Ah Paul lives in Queensland and not London. 😁 I know what you mean but I just can't resist a _misrelated participial._ I had a English english teacher at secondary and that is about all I can remember learning from him. 👍
There's generally no harm in slightly increased network decoupling capacitance; *some* issues may arise with going too far due to the inrush current requirements.
I was just going to mention you had the _capacity_ for that pun then remember it was a bloody resister and as we know, _resistance is futile._ [Insert _Collective_ sigh] 🤦♂🤦♂
Hi Paul, thank very much for sharing this great video and your big experience....great the trick about tilting the board to have another point of view....but u think can have same result using the antiglare ring light?... I use It on my selfmade arm for the electronic microscope and see a lot of difference Eg. with normal light that do reflection u can't see a brush hair....meanwhile when i switch on and regulate the antiglare i can see It other detail like dust ecc..what u think can we see even a crack on the cap? Thank for your replay and keep on sharing on open source filosofy... bye Francesco Timpano from Florence Italy
The main purpose of picking the board up and viewing at multiple angles is to neutralise the fact that no matter what sort of lighting you're using there's always going to be blind zones and/or angles that result in fault elements being rendered invisible at a specific angle. Using light at a lower incidence angle ("antiglare") you can generate shadow zones that will hide small amounts of leg corrosion close in to the body of the part. It's a good example of regardless of the tool being used, it's important to know the pros/cons and compensate accordingly.
@@pldanielsHi Paul... good morning for me in Florence and good evening for you in Queensland.. thank very much for the exaustive replay to my question and to share with us your experience, hoping can came back again to your wonderful Australia to visit my cousin Lucy and can know you bye Francesco Timpano from Florence Italy🤗🤗
It's very easy to get carried away looking for major faults when it could just be a cracked cap. I've been guilty of it more than once and have to remind myself "visual check carefully first"😆😆
So very easy and each time I catch myself removing large parts and finding out that it wasn't that, I reprimand myself fairly severely ( though the fact that I have to put it all back together is fairly decent punishment too ).
Not as impressive as the melted from the inside one a couple of videos ago. For me that rates alongside the bug that had a pee on the logic board while it was under the microscope. 😁 "Water" damage caught in living colour. 👍
Wow, hair combed back and beard trimmed. Perhaps taking Elita out for a date 😉 Meanwhile, it's nice to spend a quiet Sunday morning watching the master perform a repair. I've repaired many transceivers built with "old fashioned" through hole ceramic capacitors. I don't remember the last time a ceramic shorted. The quality of todays capacitors are 💩 🍺 Not beer but Ale or whatever it is you drink. 😂
I think the big driving factor on the cracking of MLCCs is just the astounding capacitance/volt density they're getting these days. I mean seeing 22uF 6V3 in a 1x0.5x0.5mm package is just CRAZY. Still, I'm happy for it, keeps me in business and it's something that Apple (or other manufacturers ) can't signature-ID lock to the board :)
6:04 The schematic software that Paul is using is his own excellent version of FlexBV and you too can have a copy and speed up your MacBook and iPhone repairs. pldaniels.com/flexbv/ There is also a Demo version of FlexBV available at pldaniels.com/flexbv5/getdemo.php
The summary at the end is great. Really ties these quick videos together. Thanks!
"A new thing" I suppose I'm trying. Need to put a bit more effort overall in to my video work.
it sometimes surprised me how much more you can see when the board is tilted, nice fix.
I’ve been in that situation, replacing large components too early. Thank you again for sharing your expertise with us. You truly make a difference.

What a brilliantly useful troubleshooting video! Thanks so much for sharing this kind of knowledge 👌😃
Thanks for the comment - here's hoping it is helpful for people, and if nothing else though, it's a reminder for myself :)
Always fun watching you solve these electronic faults!
It's sometimes fun to fix them... more fun to get paid for the work too ;)
@@pldaniels You get paid to do this? 😳
Good work Paul !
Very good Paul
Great fix. Well done. Thanks for sharing.

Thanks again for good educational content.
Great troubleshooting tips. Thanks Paul

Nice spot, it really proves education, knowledge, experience and skills are more economical than a parts cannon.
Certainly when all else has failed and you start resorting to slightly-random part pulling it's probably already time to walk away from the job ( unless you're dealing with something like a liquid damage area and you're hunting for a part with a dud pad etc )
The schematic and Paul's FlexBV software also played their part too.
From now on, I will also inspect more in an angle... thx
It's a "different perspective" ;) :)
@6:55 C7823 looked cracked too
A bit of grime in this case but I can see how it looks like that
Amazing channel and content, subscribed and liked.

nice work! So, is it a good measure to increase the decoupling cap values in some cases?
There's generally no harm in slightly increased network decoupling capacitance; *some* issues may arise with going too far due to the inrush current requirements.
Cracking repair (sorry for the pun!), and a beautifully packaged masterclass in less than 15 minutes!

Fanspin would the man from Austin exclaim! Oh it is an Air, no fan to pump air....
just fixed one with same and here''s a video with same issue.
😁
Same cap and board? I fear in the past I've got one that I wasn't able to fix ( we're talking 3 years ago ) and I'm thinking it was this issue.
At 12:29 the name for the user account is visible on the login screen. I don't think that should be in the video?
Thanks for that - should have known I'd miss a couple of frames somewhere (edit; should all be obscured now)
you is the best !

At this point these Apple faults feel like intended "features"
To be fair, it's happening to everyone who uses MLCCs; we just actually put the work in to fix Macbooks while we toss the PC laptops.
had replaced the audio board. had something broken inside it.
Nice, another cap bites the dust.
