While I was on vacation years ago, I met a boat design engineer for Bayliner Boats. He said they design them to last 25 hours because that's about the number of hours a typical owner will only "run"/use their boat over the course of time of owning it. No BS. People spend more time hauling and trailering, loading and unloading their boats than they do actually running them.
@@jikaikas How do they design car batteries to last exactly only the time it's under warranty? Rubber seals wear out and the longer a boat sits out of water, the faster seals dry out and cause problems.
I recently started working at an apple repair warehouse. Still in my training week (it's... ok training for parts replacement... i wish they would let us solder, but hey, gotta start someplace, and apple warehouse is gonna fucking apple). Anyway, it's 10000% intentional. That whole bullshit with the fan on the keyboard cable and this design flaw, and needing to take the fucking board out to get at the fans and the display cable... it's all intentionally designed to go kaput and be a pain in the ass to fix. I took this job mainly because it pays OK. I, unfortunately, have to follow their rules. I try not to think too much about the fact that we're not doing *real* repair, and will simply try my best to not fuck things up more than the apple storefronts are already for the customers. (btw, there *is* a procedure for recovering customer data.... well, assuming whatever is designed on the board to break so they can't get their data back doesn't break...) Anyway. This sort of thing isn't really what i wanna be doing career-wise, but if I do stick with it, in 6-12 months i'm finding someplace that *actually* cares about customers and soldering and repair.
@@falihmulyana it's not obsolescence. it's outright designing it to die if you look at it funny. planned obsolescence is where it should fail after 2-3 years, not because something randomly went wrong and killed your CPU dead.

Ohhhhhhh man. This is going to be good. Why fix what’s broken? It’ll break in a perfectly acceptable fashion for Apple. Steve Jobs: “it just works” Tim Cook: “it just breaks”
@@ElmerGLue oh absolutely. But at least for the most part, the products that came out under his reign were always progressing forward. Since he’s been gone, stagnation has really set in the past 5-6 years.

@@nils_r Those that do copy some of them but not all. Also others generally have a lower price point and better customer service while avoiding the most egregious of Apple's policies.
In regards to the backlight being controlled by varying the voltage rather than it being PWM is because with PWM the peak power is higher even though the average is the same, this shortens the lifespan of the LEDs since its peak power that slowly wears them out compared to varying the voltage. I am not surprised this problem of the power line shorting to a data line still exists though, and the fact that there was a fix in previous models that was removed for newer ones shows malicious intent.
@@DishNetworkDealerNEO Those capacitors form the output of a boost converter that takes the (typically) 14.8V from the battery and boosts it to the 40+V for the backlight LED (higher voltage is used so that connector doesn't have to pass significant amounts of current which would increase its size). PWM control in this context refers to hard switching between 0 and max voltage to achieve the same effect as varying the voltage, above a few hundred Hz our eyes perceive the average rather than the individual pulses. Cheaper electronics often use this when they want to drive LEDs. The reason why Apple would be using voltage control is that most modern devices use SMBus voltage regulators so dynamically adjusting the voltage is easily done by the PMC.
I could understand if they overlooked this in PCB design, and then modified the connecter to isolate the 50v from the rest... but considering this is YEARS later... This is so intentionally designed. THIS kind of bullshit is what should be illegal -- unnecessarily fragile design of a device that anybody with even basic knowledge in that field can see it's badly designed. Apple, a billion dollar company, meticulously inspects it's board layouts, so this 100% didn't unknowingly pass the design phase. They REFUSED to reorder the traces / design a SECOND cable for the high voltage. They also chose not to offer ANY gasket / liquid detection circuit to prevent this damage (it's brain dead simple to do, as they do in their iphones/apple watches and can mitigate). It wouldn't be as big of a deal if DELL, Acer, HP, etc did this... but APPLE with $1k+ devices? No excuse.
The tradeoff of having those series caps on the data lines is that since it blocks DC so you would need some encoding ie Manchester to not lose some bits. If you wanted to protect against a surge, which I doubt Apple would've, you would use shunt Zeners to clamp. But most designers wouldn't have to do this in the first place because they wouldn't put a big voltage next to the data lines on the connector.

just a comment but the backlight voltage in a lot of non mac laptops is just effectively vbat or vindc depending on if it's powered by the charger or the battery notable when screens only have backlight when plugged into a charger
I have to wonder, how much voltage can pure water carry? Or is there enough crap in the water, and in the surroundings to help bridge the circuts if water gets in? I mean salt water, coke, any liquid with stuff in it. But straight up water, if PURE enough, can act as an insulator. Sort of... I guess I need to see if Electroboom has done any videos on this.
@@vulkandrache1928 this seems like a job for... ELECTROBOOM! also with enough voltage, it can probably arc with as short a gap as that connection has. Especially if there's ANY sort of conduit.
Some do use PWM to the LEDs, the reason not to is: PWM is, at it's most basic, is flickering a light on and off very fast to make it "look" dimmer. If you don't get the frequency correct it might line up with the screen refresh rate and cause strange effects. Apple does use PWM in this circuit but not to directly drive the LED strip, it controls the voltage. You can find examples of this somewhere on this channel. About 3 years ago, right after I got a real desk in the old store, I was sitting directly behind Louis. He changed the camera angle to behind him so you saw his computer monitor in the shot. His cheap Seiki monitor used PWM to directly drive the LED backlight. If he had the monitor on anything other then full brightness it would cause a flickering or rolling shutter effect on stream. It was the only monitor in the shop to do this.
Why not use coffee filters for cleaning off thermal compound? You can get them in bulk incredibly cheap You are right, though, that paper towels can work just fine if you’re careful.
Their contingencies are for getting you into the store to charge you $1500.00 They want to be sure that if the device doesn't just automatically fail, the customer will surely damage it in some way.

Hi, thanks for the video but I have a question. If this MUX is wrong. Can the internal screen has brightness? and, Will I have external video trough the USBC connector? I have a MBP 2141 (2019) and the internal screen has brightness but no image. Also, when I connect an external screen trough the USBC it works perfectly. Touch bar is also ok so everything is ok and the only problem is that the internal screen doesn't display anything. I can't try with another display and I just want to know if this mux could be a possibility in my case (the flex cable of my screen looks like ok but maybe the TCON is cooked (?)). Thanks for your videos Louis!!
I've never been a Mac guy, but I was just provided an A2141 by a new employer... Something tells me I'll continue to never be a Mac guy. This stuff is ridiculous!

Most of your statements were more true even five years ago.

Wow, an (important) detail for sure. I can not help but wonder: Apple does attract SO much attention due to their practices and expensive hardware. I'm sure that other manufacturers could screw this over as well. Do their engineering process change even a little bit towards producing better quality hardware? I know that they screw things, but with the competition raging is there any improvement? They better improve!
I've seen some dumbass things in military equipment....how about a cannon plug that is keyed identically on three drawers of circuitry. The bottom drawer contained the power supply ( among other things ). The same pin on the bottom-most cannon plug had 120VAC as the upper two drawers that had - +5VDC. Yep. Imagine when a drunk technician plugged the wrong cannon plug from an upper drawer into the bottom drawer. Took me WEEKS to fix that idiot's drunken mistake.
You know if apple really didnt want anyone to repair their stuff and only replace, they could glue in each M/B to the point that it will rip out the traces and do so much damage trying to get it out. Theres glue that you just cant release no matter how hard you try and they already do this to batteries- its the reason they are so worshipped and rich. Total consumer buy and replace. Anyway the boards components and chips are so small and unable to be bought, only the best can repair and thus charge a lot making replacement the only viable option. This can be changed and this channel and others and me would like this, but its a tough road and people are so unskilled these days, they so used to just buying another item and they can be cheap to for other brands so repair as much as i like to do, well may eventually not be worth it as things get cheaper for same tech levels.
We are not coming out with new revolutionary battery techs, they are practically at their limit and may rust spontaneous combustion if they keep cramming cells so close together, might be different for fuel cells if we ever manage to contain hydrogen
Tesla didn't solve the range problem. Tesla solved the problem of being able to put enough charge into the battery on a short stop to be worthwhile. IIRC, you can get a Tesla's battery pack from ~20% to ~80% in about 20 minutes. That means you can get a few hours runtime on the charge you can get into it when you stop for a bathroom break and a snack. Not as good as being able to refill the car in a couple of minutes like you an with gas or diesel, but it works. I have two problems with Teslas: One is that they're pretty much what Apple would do if they built a car: The hood is welded shut. The other is that garbage center console. A center console needs to be something you can operate by touch without looking at it so you can keep your eyes on the road while you adjust the radio or the HVAC. Touchscreens are the one thing you shouldn't have for the controls of anything you want the driver of a car to be able to operate while driving.
I appreciate your dedication and excellence of repair and your Marine homilies. I think America is ready for electric cars. I just think batteries are not yet ready. If you could right now buy a used electric car and have the same longevity as the original owner then I would say, yes let's do it. Just wait till 2030 and gas is 15 dollars a gallon people will be selling their children for one of these type cars that charge off your rooftop. Flywheel batteries for the home where you dig a pit in the back yard like for a cesspool will make them perfectly safe but your car will need one of those really robust batteries not like current lithium ion.

Imagine when a drunk technician plugged the wrong cannon plug from an upper drawer into the bottom drawer. Took me WEEKS to fix that idiot's drunken mistake.
You know if apple really didnt want anyone to repair their stuff and only replace, they could glue in each M/B to the point that it will rip out the traces and do so much damage trying to get it out. Theres glue that you just cant release no matter how hard you try and they already do this to batteries- its the reason they are so worshipped and rich. Total consumer buy and replace. Anyway the boards components and chips are so small and unable to be bought, only the best can repair and thus charge a lot making replacement the only viable option.
This can be changed and this channel and others and me would like this, but its a tough road and people are so unskilled these days, they so used to just buying another item and they can be cheap to for other brands so repair as much as i like to do, well may eventually not be worth it as things get cheaper for same tech levels.
I think they wanted to punish the factory workers. Bet you their pay doesn't go up.
We are not coming out with new revolutionary battery techs, they are practically at their limit and may rust spontaneous combustion if they keep cramming cells so close together, might be different for fuel cells if we ever manage to contain hydrogen
How meta, I'm watching an a2141 repair on my a2141
Hopefully it will run long enough to let you watch to the end of the video ....
Tesla didn't solve the range problem. Tesla solved the problem of being able to put enough charge into the battery on a short stop to be worthwhile. IIRC, you can get a Tesla's battery pack from ~20% to ~80% in about 20 minutes. That means you can get a few hours runtime on the charge you can get into it when you stop for a bathroom break and a snack. Not as good as being able to refill the car in a couple of minutes like you an with gas or diesel, but it works.
I have two problems with Teslas: One is that they're pretty much what Apple would do if they built a car: The hood is welded shut. The other is that garbage center console. A center console needs to be something you can operate by touch without looking at it so you can keep your eyes on the road while you adjust the radio or the HVAC. Touchscreens are the one thing you shouldn't have for the controls of anything you want the driver of a car to be able to operate while driving.
You can burn down your house with having a crap load of batteries at your house.
I appreciate your dedication and excellence of repair and your Marine homilies. I think America is ready for electric cars. I just think batteries are not yet ready. If you could right now buy a used electric car and have the same longevity as the original owner then I would say, yes let's do it. Just wait till 2030 and gas is 15 dollars a gallon people will be selling their children for one of these type cars that charge off your rooftop. Flywheel batteries for the home where you dig a pit in the back yard like for a cesspool will make them perfectly safe but your car will need one of those really robust batteries not like current lithium ion.

I like pauls calm demeanor. but the mic needs about half an inch more distance from the mouth to not pick up every breath, unless you're into ASMR. im not kink shaming .great vidy tho
No : /
coming from apple? not surprised.
What’s the design flaw specifically?
Judging from the thumbnail alone, JTAG connector. That damn thing is ALWAYS screwing up on Mac's, and really shouldn't be on there outside the factory anyway.
Besides the whole thing? The fact there is no Ground between the backlight LED output voltage and a data line that goes to your CPU.
high volt line too close to a low voltage data line for the graphics display
It's a water damage issue. He says it himself that this isn't an issue if it doesn't get wet. So... I wonder if you can actually call this a design flaw. You aren't supposed to get your laptops wet.
@@Lumilicious ok all knowing god, accidents never happen, moisture doesnt exist on this planet, and Apple devices should only be used in the great USA.
It's intentional, to try and sell a new machine.
🤔 Guess Apple's design for water ingress failed IEC 60529 and ISO 20653...but what ingress standards does Apple actually test to?
None whatsoever by the looks of it..
All I hear is "pee pee bus"
Don’t you get it, it’s intentional !!!!!!
well, theres no need to fix it. money is still pouring in
they do it intentionally.
I wouldn't be surprised that most of those 59 volts goes to the illuminated logo. Nice
Its apple so its not flaw. Its feature
You could’ve easily prevented any heat damage to all the chips around the MUX chip by protecting them with some Kapton tape, that’s a basic precaution when working around heat sensitive circuitry. Did you learn anything from Lous? Also, why the fuck would you be using a paper towel to clean a critical part that requires to be spotless, you know they make lint free dry cleaning wipes especially made for the task of wiping something like a CPU/GPU die??
No... Just no.
Military and automotive plan for contingency. Apple plan for obsolesce.
Is it just me, or does this guy sound like George Lucas?
it´s so ... Apple !
Yes, attention to detail, but then realizes you forgot your screw driver in the first few seconds x3
Design flaws happen. Typically an fmea finds most. The insensitive structure in place here is certainly less than ideal.
