This XsMax repair is a lesson that "see broken, fix broken" isn't always the best strategy for troubleshooting iPhone logic board problems.

Great job using human logic, schematic, and multi-meter. Great to see this done on modern hi-density circuit boards. I used to do this on old tube equipment when you could get schematics from SAMS. All functional logic knowing what is supposed to happen in different parts to the electronics.

@elijahchigwada7093 5 жыл бұрын

Awesome video. Just wanted to point out that those small capacitors (220 pF) play an important role as they are decoupling capacitors that short high frequency noise to GND. Yes everything will work fine without them but if you ever get noise in that line you are going to fry whatever is connected on that line. I would place those caps back just to be cautious.

I am certainly glad to have a channel on KZfaq like like yours.. I catch myself watching and watching. Instead of surfing now. Spent the last 35 yearsand in our county in state you have to be certified master technician for seven different things to be able to hold license here. Electronics is one of them.I'm just so staggered watching you fix something. That one got to me 😂.keep up the awesome work in I'll be watching you and throw in a comment every once in awhile if you don't know something.. 👍

I consider sucessfull troubleshooting to be a fine art requiring imagination (where is the schematic?) and experience in knowing the path and walking the path..... great video! :-)

You have 2 qualities that rarely go together. You are extremely intelligent and have this way of explaining things that average everyday Joes like me can understand. The other thing that I love is your process of diagnosing. Sometimes you have to use common sense and logic BEFORE pulling out the test equipment and schematics. Keep on keepin on.

Muy bueno. Gracias!!! En realidad lo que aprecio de sus reparaciones. es el enfoque. el leer entre líneas que es lo que debe aprender a hacer un tecnico en reparaciones, además de contar con el equipamiento adecuado por supuesto. Me interesa mucho aprender su método de enfoque, allí yo creo está todo el secreto de reparar cosas.

I love this stuff. The videos here kinda feel like the yin to Rossmann's yang. Not saying either is wrong or right, good or bad, but the approach to almost everything, is very different. I firmly believe, that with the repositories of both available, and the will to put in the work - _anyone_ with two reasonably stable hands and at least one eye (but preferably two) - can learn to do this.

Those filters "that don't act like coils" appear to form a common mode choke filter. That would make sense on a differential input like that video chip is using. Excellent video and teaching.

@ time 11:24: More than likely. at one point in time, the development team were working off of spec, and not actual hardware. i.e. they were using a similar LCD panel for testing purposes, and not the final product panel, and using this small circuit as a sort of "disposable" adapter to test the board. Once they were able to test with the actual end-product panel, this circuit would have been removed from from the pick-n-place program. (less costly than rebatching all the boards, and less costly than having design engineers layout a new board design just to omit this development circuit) This sort of thing is common practice, if you've ever pulled a complex board from just about any device (phone, computer, that one unique gift idea from ebay.cn) You'll find quite a lot of non-populated areas, and even whole circuits. This is also used to differentiate "models" or teired of the same product. I.E. If one phone has 64gb of SDRAM, and the cheaper model only has 32gb, with no other discernible difference, you can bet your bottom dollar they will use the same board, and simply de-populate that extra SDRAM circuit. It's cost effective.

220PF may be small, but it's better at cleaning RF from that line than an electrolytic.

When doing this video you should have also checked between the 3 pins for continuity after replacing the choke (as you know it’s very easy to bridge the pads at the inductor)
