I'm not a huge fan of Louis's attitude, but the issue I have is with Right to Repair, not Louis. If he helps further the whole Right to Repair, then he can complain all he wants. Apple has lots of quirks and defects, but Dell, HP, Lenovo, etc all have their own faults. That being said, Apple really screwed up with the iPhone 6/6 Plus design. Why did they put underfill on all ICs
except the touch controller? Why did they then relocate the touch controller to the display on the 6S/6S Plus? If it was such a great design choice, why change it? If the aluminum was strong in the 6/6 Plus why did they change the aluminum alloy to a stronger aluminum in the 6S/6S Plus version?
Another example that I didn't know about until I recently when I was working on one, is that the display connector layout changed in the 2016 Touch Bar machines. From at least 2006 until the Touch Bar models Apple used a LVDS connector and the pinout kept the display data lines separated from the 40-50V backlight lines with several traces connecting to ground. Should a short occur from liquid damage or humidity cause corrosion, the backlight voltage would short to ground and blow the fuse on the board. Well with the newer Touch Bar machines, this press on connector has a 50V backlight line right next to a data line. Humidity can cause slight corrosion which becomes conductive. Those data lines are fragile, and putting backlight voltage on them damages the MUX IC on discrete graphics machines or damages the CPU on the 13" models. You would easily damage USB equipment if you applied 5V to the data lines instead of keeping that voltage on the power lines.
Again, I think he's overly critical on numerous things, but I do hope for a day where people have a right to repair their own machines. I have the service manual, exploded view, wiring layout (w/ pinouts), engine diagnostics and rebuilding specifications for my Mazda RX-8 and an old W220 S500. I've got a board layout, schematic, BOM and service guide for my audio gear, some as old as 1978, some as new as 2009.
I was recently working on a HomePod that made a random popping noise.
I determined the problem to be the with the Class D amplifier IC that was putting out DC offset and literally cooking the voice coil of the woofer. It's part 98-0431, by International Rectifier (now owned by Infineon) Pin out wise it's similar to the
PowlRaudio ICs for sale from Mouser/DigiKey, but not identical. Contacting Infineon got me this response
Hello Nick,
Please note that the part number 98-0431 is not a standard Infineon/IR part number. This is actually a custom part which was manufactured for an OEM. Please contact the manufacturer of the equipment being repaired for more information on this part or for a recommended replacement.
Best regards,
Infineon Technologies
It's no more than an $8 part, and obviously no "Genius" or Apple rep knows **** about it because it's something that only the engineers would be familiar with. The amp board's Apple part number is 820-00077-08, but there's no schematic available, so one can't easily diagnose any other issues. Of course Apple isn't going to sell part 820-00077-08 to the public, and if they did, they'd probably charge $250 when you could buy a whole new HomePod for $299
Keep in mind Apple doesn't repair your product. They replace it or replace the defective part/assembly in the product. Apple doesn't troubleshoot devices like AirPods or HomePods (see above video) Heck I doubt Apple's Genius technicians know what "DC offset" even means.? They ship the device or defective/broken part/assembly to China where children working in a sweatshop do board rework. Sometimes those kids don't do a good job. I had a replacement MBP logic board for my own computer come to the shop with a damaged keyboard connector. Had to mark that board as DOA and they resent another. Now they get to send the poorly reworked board and the original defective board back to China to be corrected. I've also seen replacement boards come with scratches, poorly soldered components and liquid damage. Do you want your defective board to be replaced with a refurbished but previously liquid damaged logic board?? We also had a problem for a while where the top cases for the white unibody MacBook A1342 weren't glued properly. The top plastic area above they keyboard wasn't glued to the metal internal frame. We notified Apple, but nothing was done for a few months. In the end we super glued 50-70 of those top cases before proceeding with repairs.
I find it concerning that they are soldering the storage to the logic board rather than use a socket like they previously did. Soldering the ram was okay with me since I often have to re-seat ram in people's laptops (MacBooks included) when they get knocked over, but soldering my data to the logic board is excessive and is a great example of form over function considering SSD's can easily wear out before anything else does.
I take it most of the people here have never used screw driver, multi meter or even a soldering iron, and would rather pay Apple to swap components for them, and that's okay, it's your money. Some of us want the ability to work on our equipment. I work 40 hours a week soldering components to PCBs under a microscope so I'm familiar with what Louis actually does. Can any of you solder these? Don't worry, they get much smaller than those 0603 resistors on the first photo.
