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 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
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
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!
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!!!
Great repair video. The shorted ISL chip blow the 20 ohm R7005 resistor .
I would say out of all your videos I think this is the best one.
مبدع كالعاده.... فن واتقان وتركيز في تحديد العطل
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" :-)
View from Germany I love this work and Alex you are so friendly all ways thank you very much you make My Day better
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!
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.
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.
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.
Where do you get your schematics and diagrams?
I'm glad that we were able to get this board fixed
you are only the who make my day;cheering me up by such awesome;informative vids i appreciate your work
Thank you. Great video. You read those diagrams pretty well. Awesome
Best video you made by far you went step by step explaining thanks bro am trying to learn
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
Would like to see more videos like this...schematics, voltages, and component values.
How do you get doner board
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
Good Jobs and you have newer been used thermal cam on this.Bravo
U are the best. Love you from Zimbabwe
great job, all error component measured before change
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 excellent video, full of maintenance knowledge, please pay attention to it!
Very interesting and excellent troubleshooting techniques may i know which board viewer you using ? Thanks.
The power of schematics is just amazing. I need schematics to fix my laptop.
Witch multimeter are you useing?
tnx and all the best!
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
After a long time advance repair video is here 👌👍...just a quick question which software you are using for bitmap view?
Pursuit of Perfection ...well done 👍
Hello, what is the name of the software you're using for the board view?
يازلمي طلعت عربي وانا عم قول هالذكاء والبراعة بالشغل من وين جايبها 👍
Great job bro.... learning new things day by day 👍
Nice work!
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!!!!
Without schematic, can your thermal cam be useful to find resistor problem ?
I hate all the Apple's related products but I don't miss any video of yours on repair process.
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?
Thank you. Now I know where to fix my MacBook.
Maestro, great job!
Please shoot the next video about that macbook which you said the keyboard and touch pad are not working. Love from Tanzania 🇹🇿
Great work!! it is so beautiful and perfectt
Great job, I hope to be as good as you some day.
excellent job, enjoyed it and learned...
Which website do you find the Schematics
Excellent job brother your very good!!
Excellent work! Congrats! 😅👍
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 )
Really appreciate your work
Best video ever from Hussain bro,
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?
Amazing like usually !!
great video ! is that the software from Paul Daniels ???
just asking, have you ever fix a graphic card before?
a long process, and i like it 🥳
Nice work!!
Good job sir from the phlippines also a cellphone technitian..
Nice job!
Where can get the laptop schematic,
Where can I find schematic for apple products? Please help
nice video from philippines
Good work sir
you men are a hero....
ماشاء الله مدير
View from Germany
Great job 👌
Great job like all ways
Just like I've always said Alex... "It's better to pay a tech than to make it a wreck!"
I've liked this video sooo much
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.
You r great..., 🇮🇳🇮🇳
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
Brilliant!
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.
Respected SIR. How we can have circuit diagram for defferent laptop
Thanks
your very good
Thanks , i from vietnam...
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
Wow so nice
Thanks
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?
view from INDIA .............
Like you uncle calls you. The boss of them all.
NIce job 👍
Superb
What software do you use, do it's FBV ?
FlexBV yes
First from Philippines 🇵🇭🇵🇭🇵🇭
Mabuhay ang Pilipinas! 💪
Edi wow😆
gogo pilipinas
cool one
I'm just curious. Does anyone have a guess as to what happened to make all those components fail or break? Just wondering.....
Chip died. Passives were collateral damage.
Hi. Engineer, I had a question. How can I find a schematic of an electronic SMD board on the Internet? For example dvd player marshal portable model ME-118MKII Thank you for replying.
Brother i remember you asking the same question before, usually i type the model number even if it is a Chinese brand, sometimes I get lucky sometimes I don't, good luck
Also some of the schematic like the iPhones can be bought online or you can get a paid subscription, i think
Try paul Daniels software
How you enter search criteria in Google will improve chance of finding factory service data. Use keywords like "service manual", "repair", "schematic" and ".pdf" with model number of device (like your DVD player). Check OEM's website for support documents. Look for identifying information printed on the boards and search it; a lot of OEM's use subsections that are readily available from third party manufacturers (e.g. logic boards, power supplies, motor controllers, audio amplifiers and LED drivers). If you cannot find service data, then get pencil and paper and reverse engineer device yourself. GOOD LUCK.
Due to Apple's litigious 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.
Where did you find schematics and which software you use?
I will also like to know pls.
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.
awesome
