I soldered my first eeprom for a lcd tv this morning. This was my first venture into replacing an smd component. You sir, make it appear pretty easy. It is not. I need to thank the guy at the local computer repair store near me, for the small tube of no clean flux. It saved my tail after lifting and bridging two pads. Got the pads separated and back where they needed to sit. I learned a hot enough iron(I dont have air) and flux are very important. Your videos are great inspiration to believe I could try. Job done, big smile and on to the next one!
I am just a beginner at micro soldering, and my weakest area is in diagnostics. I've learned a lot from your videos on the usefulness of the visual inspection of components, and loved this one on following the schematics. (I'm sort of glad I don't do Macbook repair!) Thank you for sharing
مبدع كالعاده.... فن واتقان وتركيز في تحديد العطل
Liked and subscribed! Really loved watching the entire video. It's awesome to watch you follow the diagram, read the values and then measure the values on the board. Obviously you have experience, because I would not have known to look for example to the current resistors and that chip. Thanks!
I am so glad you answered a question that I have been wondering for a long time about what happens when resistors go bad. I took a lot of notes at iPad rehab and maybe it was covered but that just didn't stick in my head of how they act. I was also making mistakes in my macbook repairs when I didn't check the resistors while the power is one Thank You so much!!!
I've learnt a lot from your videos and also teaching other colleagues too. I always find it intriguing that u rarely use schematics drawings in your diagnostics. Good work!
One of my favorite category in repair. Dead unit and step by step checking of power rails before giving conclusion to the device. Keep it up sir, i learn a lot from your videos. Repair Tech from PH.
is there another page that you follow that explains step by step macbook?
I would say out of all your videos I think this is the best one.
Great repair video. The shorted ISL chip blow the 20 ohm R7005 resistor .
View from Germany I love this work and Alex you are so friendly all ways thank you very much you make My Day better
I have learned a lot from your videos.I am very thankful to you sir. Love from India
Very very interesting video with schematics, circuit board and step by step troubleshooting method. Like you use to say : "AWESOME" :-)
Thank you. Great video. You read those diagrams pretty well. Awesome
Love watching your channel, keep up the good work. I just wanted to share a thought about the general topic of your channel. It feels so good to repair things that were complex and looked like they were basically broken. I imagine you get that feeling too? I guess you make some money from these videos, so I can't say it's 'for free', but considering we the viewers do not pay out of our pockets, it's a fair trade with everyone winning here, obviously some more than others (google), but just wanted to appreciate your sharing of expertise.
you are only the who make my day;cheering me up by such awesome;informative vids i appreciate your work
Pursuit of Perfection ...well done 👍
Some extra kudos to you - unlike some other channels, no foul language here; down to earth and to the point; strong diagnosis; results - thank you for the nice video
Yep, without diagram this was a no fix! Because you can’t test every single resistor!
You can still track the power rail though!
Every time I see that good component level repair I feel really good, this should be done everywhere! Absolutely love it 😍 that’s amazing!
Best video you made by far you went step by step explaining thanks bro am trying to learn
Maestro, great job!
Great job bro.... learning new things day by day 👍
Nice troubleshooting, NF 👍. Many boards are scrapped unnecessarily due to lack of logical troubleshooting. The hackers might correctly replace a dead chip, but fail to troubleshoot, and miss the damaged passives. They give up. Client loses.
Amazing like usually !!
U are the best. Love you from Zimbabwe
Good Jobs and you have newer been used thermal cam on this.Bravo
Really appreciate your work
These should be PSA videos on why you shouldn't buy mac computer's. But nothing will stop people from buying what they see In ads.
As always amazing work great knowledge and process.
excellent job, enjoyed it and learned...
Great work!! it is so beautiful and perfectt
Hello sir , job well done 👍 I like the way you work and find you skills is very different ! And try to get the same tools you use I know can find them on your site ! My work has stop moving I have nothing coming in
great job, all error component measured before change
Excellent job brother your very good!!
Nice work!
I'm glad that we were able to get this board fixed
Would like to see more videos like this...schematics, voltages, and component values.
How do you get doner board
Excellent work! Congrats! 😅👍
As far as I learned from you, I would have changed the chip first then changed after diagnose then outer components... but anyway i am still learning... thank you master flash 🙏
Logical troubleshooting is usually faster than educated guesses. After much experience, educated guesses are fast but still check. It avoids getting confused when you guess incorrectly. If we don't have a stack of doners, guessing gets expensive and time-consuming.
Again a nice job.
Can you tell us what for a Soldering Station y use? And also explain how to solder like you. Like how to hold the solder nicely on your tip and bring it to the board.
Would be awesome ❤
Very interesting and excellent troubleshooting techniques may i know which board viewer you using ? Thanks.
a long process, and i like it 🥳
Nice work!!
After a long time advance repair video is here 👌👍...just a quick question which software you are using for bitmap view?
Great job, I hope to be as good as you some day.
you men are a hero....
Nice job!
Great job 👌
Great job like all ways
Brilliant!
Having Board View is so nice. I love working on MBPs because of it. If only we could get that for other makes/models as easily.
Great work. What chip kit did you pull the ISL from? I don't remember seeing that one on the store.
From magic box )
Best video ever from Hussain bro,
Verry good job ,but I wanna ask you if you can show the multimeter on the screen at the same time to follow your explications thank's again
Very excellent video, full of maintenance knowledge, please pay attention to it!
nice video from philippines
I've liked this video sooo much
Good work sir
Good job sir from the phlippines also a cellphone technitian..
Where do you get your schematics and diagrams?
You r great..., 🇮🇳🇮🇳
يازلمي طلعت عربي وانا عم قول هالذكاء والبراعة بالشغل من وين جايبها 👍
NIce job 👍
great video ! is that the software from Paul Daniels ???
Thanks , i from vietnam...
Thanks
your very good

I hate all the Apple's related products but I don't miss any video of yours on repair process.
Absolutely enjoyed watching this
excellent step by step troubleshooting. Would you share wich board viewer you using. Is it open board view developed by Paul daniel ?
Yes FlexBV
@@mariolemerise7732 thanks
Please shoot the next video about that macbook which you said the keyboard and touch pad are not working. Love from Tanzania 🇹🇿
hey :)
i am trying to repair a siemens s7-200 sps.....do you have a tip for getting the scematic of the psu?
good work that you make!
best geez from Germany.
PS: sorry for my poor english!!!!
Witch multimeter are you useing?
tnx and all the best!
Wow so nice
If this repair took you 20 minutes to troubleshoot I salute you 👏.
This is a very common repair to do. Same IC AND same 5 resistors and the twin diode package to check. 5 min diagnosis mate
Thank you. Now I know where to fix my MacBook.
Superb
The power of schematics is just amazing. I need schematics to fix my laptop.
cool one
Awesome ✌🏻✌🏻✌🏻

Without schematic, can your thermal cam be useful to find resistor problem ?
awesome
Do you have any videos for the same mpb but with a slow flashing green ? I recently replaced a battery and mag safe charger (port as well) and machine is still not charging. Prior to the battery swap and replacement charger, light would stay green and lightning bolt would show charging but indicator lights on the side were blank. With the new charger it will pulse between charging and not (charging indicators) but shoes battery not charging on screen
Continue, artist
nice job again!
A question:
Why you get parts like resistors or caps from donor boards when you know their exact value? Not saying it's wrong, just wondering why.
Have a good day! Greetings from Greece!
It’s Usually the quality, value and tolerances are all tightly matched to OEM specifications whereas sometimes new parts from different manufactures aren’t of correct tolerances or values !
Well it can't be quality since that is a common failure on these boards (ask louis :D), also you can get parts with better specs from any electronics supplier, so I guess it's convenience since they are already there.. on the donor. also you don't have to pay for extra parts. If you want to have a stock of all components that you might need to replace in the future you have to pay a lot of money for that... (having i.e a hundred of each possible cap and resistor you might need, you are quickly in the thousands of dollars ...)
I really don't think it's a good idea to solder the same crap back on from another board since these donor board parts are most likely prone to fail like the ones that did in the first place....probably they are close to end of life.... just MO.
@@rajawaseem2752 No, this is not entirely true. Basically, one doesn't need a very tight tolerance value in the larger majority of the cases unless of very precise reference voltage value for comparators or regulators. The reason for using donor boards is that you have a perfect corresponding component point to point. So, you do not care of the value of the component, since it is in the same position both on the board to repair and on the donor board. It is a quicker path to solution! Regards from Italy.
A little bit concerned that three resistors failed. Resistors don’t usually fail for no reason. Is there some problem on the board that is blowing those resistors? I know you are trying to work quickly but perhaps a little bit too quick?
just curious cos I haven't seen or even touch a MacBook motherboard yet. is the chip that you replaced are all the same on every MacBook.
The chip he replaced is a QFN charging IC (ISL6259). You'll find this chip on all Apple portables but it could differ with the portable model.
متميز دائما
just asking, have you ever fix a graphic card before?
How to become master like you sir.....you are great .....specially in microsoldering...
It's easy just you need micro soldering skills and test board to practice and make them perfect
You may learn them via youtube or just try by your self on dead boards
Hello, what is the name of the software you're using for the board view?
I'm on a 10" tablet and I have 70-year-old eyes. Can you enlarge your cursor for schematic pointing? Thanks!
My eyes aren't as old but watching on my phone I had to zoom in with my face to see it lol.
Like you uncle calls you. The boss of them all.
0:50 Is that normal?
yes i see that first too, but on second look its just melted plastic from connector
leftover flux
I think it's toast.
Probably the reason why the DC IN board had to be replaced.
I have a 2009 MacBook Pro that after changing the battery will boot up and then goes to a white screen and does nothing. Is it even worth attempting to repair it?
Right now I have a package at your post office that they say they can't deliver to you. I requested a redelivery try. We'll see. Iread car diagrams every day. Where do you get computer diagrams?
Excuse me, from where can I have schematic and diagrams for Mac ?
I would like to get a course for advance repair, from where I can get courses for that?
Thank you for your amazing videos
From Saudi.
Due to Apple's litigious nature one does not post where to download schematics but if you use Google or other search engine you no doubt will get results. Some schematics are hard to find.
@@GregM Thank you!
Just like I've always said Alex... "It's better to pay a tech than to make it a wreck!"
Board view is op lol wish other brands had as much leaked schematics and that program
It'a probably not worth making such a program for other brands.
@@roseelectronics4582 ya I know wish the amount of schematics they have for apple were floating around for other brands though
🔥🔥🔥🔥
What software do you use, do it's FBV ?
FlexBV yes
