You are what I would call a competent IT technician, bar none. God-tier.
Been watching you since 2013, 5th grade, glad to see you making videos still, thank you for inspiring me to work on electronics!
I really hope the customer gets to watch the skill and intelligence applied to this fix. Well done very impressed. Keep em coming !
Excellent diagnostic lesson Graham. I'm glad you found the solution.
Done watching, thank you very much for the informative repair video. I have learned significantly more troubleshooting & repair lessons in this tutorial video and to your other repair videos as well compared to my ENTIRE 4 YEARS OF COLLEGE due to the rotten & outdated standards of education here in the Philippines. I hope you will soon have a mini-series for Schematic & Boardview-free Voltage/Power Rail Tracing[12V/18-20V Main Voltage Rail, 5V, 3.3V, CPU/GPU Core Voltage Rail, DRAM Voltage Rail, IGPU Voltage Rail, System Agent/Northbridge Voltage Rail, PCH Voltage Rail, BIOS Voltage Rail, Battery Power Rail], Proper method of testing/checking of potentially faulty MOSFETs & ICs/Controller Chips, CPU/GPU/PCH Reballing and BIOS Bin File Editing.
That looked like a difficult fix you were well pleased at the end. Love to see it.
I love the real frustration! You are right.. sometimes stuff just starts working.. or quits for absolutely no reason.... UGH. GREAT VIDEO SIR!
Thanks for sharing your amazing skills! I fixed one of these same machines but simply replaced the logic board. Very impressive to see the board actually repaired. 👍
always love learning things from your videos as always thanks for sharing your knowledge too.
That was a pain staking operation right there lol Nice work , enjoyed the video.
Great diagnostic process, Graham. And I think you may be right...maybe cycling between hot and cold causing condensation sticking to the dust.
great repair job!
A very nice video again thnx.
You're very good in your job !
0201 resistors, eek!
I get the feeling I'd make a huge mess of things, the frustration with such tiny components...
I've been watching your repair channel for a couple of years, and I'd like to recommend you install an intake and exhaust venting system - especially when dusting off who knows what dust contamination, and for the solder fumes. Just concerned about your long term health.
Nice work, good video, didn't look like you'd have had a problem diagnosing this if it wasn't so obvious anyway!
Would have been less of a struggle if you had the resistor pads pre-tinned with leaded solder
your videos are even more fascinating given this evermore disposable society.......
Do yourself a favor and use rosin for these small resistors, it will not evaporate and will keep them glued to surface until solder melt much better than synthetic flux.
Nice one. 👌
That's a lucky one because sometimes having water dammage on the 5v ic it's the PCH that ends up thoast 🙃
Amazing work in fine detail. I sometimes have trouble getting my key in the front door lock and here you are soldering 1mm parts on a board.
Well done.
Love your video's only your volt/ampere meter indicator is so jumpy I almost get an epileptic seizure
0201 is about 0.6mm x 0.3mm :)
Ideas: put the board on a preheater and clean the old solder away with wick before placing the donor parts.
I want to do this kind of work, I’m currently enrolled in computer science at college but have been heavily debating if I’d be more suited with computer engineering/electrical engineering.
With the tarnished points across the board, I am dismayed that there isnt some form of water repellent coating protecting it at least to a certain extent. Im thinking something like the nail varnish coating people use when doing delidding for liquid metal.
No, no water shields, no conformal coating. You might almost think that Apple intentionally design them with nonexistent water ingress protection to make them more disposable.
I almost always drop/lose motherboard screws while building PCs. I'd have no chance of keeping track of tiny laptop motherboard components.
Great video overall, but I noticed that boot was unusually slow, did you check for sensors using HW monitor tools once it booted?
Yea it seemed fine, but it's a 1,8GHz 4GB board, so it's not exactly a speedy boi😔
If liquid damage happens so often why don't they just coat the boards with some protective layer?
nice video
20.42 computer says no :)
Unfortunately, your amazing skill and prowess saved another POS overpriced and proprietary Apple product. Amazed at your skill in these videos.
When you say 425 degrees is that Celsius or Fahrenheit
Hey man, I was working on a 1466 that had power and backlight issues and I had the original charger. Where can I find a cable that I can plug into my power supply or meter to measure the draw?
Search ebay for magsafe 2 cable, and you can buy the bare cable. Or you can cut one off of a dead charger. These days I have a Paul L Daniels type-c meter, and I use a Type-C to MagSafe 2 cable with that.
Well, you say 10 thousand billion, but I do believe it is actually 10.01 thousand billion
Fine video. You should have checked the resistors before you desoldered them. Not everyone has computer program to assist them. I’ll leave it at that. Thank you
I actually did, but I cut the section of the video because I was getting inconclusive results that didn't really say anything. I thought that might be indicative of the bad resistor (open line, so it gave a nonsense in-circuit reading) but after I replaced the resistor, I got the same nonsense reading. It might've been worth leaving in as a demonstration that in-circuit measurements can be deceiving, but the video was already pushing run-time.
Bring back the old intro music!
You might consider getting hot tweezers
Hey, how do i post a macbook to you?
Graham, im also a tech can i ask one thing hope you reply, are you using desktop or laptop as computer repair assitant like for instance file tranfer and amusement while waiting for any jobs in your shop, thanks
My main work PC is on the repair bench, which does the video recording and is also references and other repair tools, then I have another PC on a different bench for data backup and restore.
@@Adamant_IT thank you so much for the response, im a big fan of yours, i like the way you solve hardware issues including no power etc, every time im on off duty i watch a lot of your videos, thanks again
Let's Fix Macbooks
Great fix but are Apple laptops that slow to load?
Depends. If the macOS install has had some false starts, it'll likely fsck the drive on the next boot, which slows things down. But also macs in general aren't famous for their boot time. They sleep/wake quickly instead.
That looks like vape damage and dust (caused by vaping).
Vape covers with a sticky liquid which is impossible to remove, except with water. One cannot put water on a board. Maybe there is another way but I don not know it.
Stressy!
Do you mean 1ml of damage in the thumbnail?
Great find, the guy on a guy was dodgy and the survey says khotta de towee. Brilliant
Does the customer live in a barn?
Crapple
“Crapple” is about to crap on x86 with their power efficient Apple silicon but sure thing my brotha
Apple logo, the symbol of evil.
Nah here’s the real symbol of evil: $
