A1989 MacBook Pro 2018 820-00850 Stuck at 5v Live Stream 7/17/21

This MacBook Pro has a bad CD3215 USB-C Thunderbolt 3 controller chip. This IC is known for random failure, or failing when an accessory, such as a inexpensive HDMI adapter, kills the chip. This particular repair takes a longer than normal time since the chip is underfilled.

Thanks for the video and sorry that I missed the livestream. A disadvantage of living in Australia :) I have yet to tackle an underfilled CD3215 but I am not in a hurry. Nice job iRevive

[@optimizelogicrepair2784]

Excellent!

[@iRevive]

Thanks!

[@MrPnew1]

Note to myself - UB300 is CD3215 being replaced, U8800 is the SSD NAND being protected by a penny

[@iRevive]

You are correct. The coin method is a method I would use for iPhones when working on components next to underfilled ICs. I have been hearing more lately that the coin method might actually require more heat on the board. Knock on wood, I have yet to run into any issues with the coin method. But there are mixed feelings using a coin to protect specific chips.

@@iRevive love your videos as I always learn something new and you have a calm professional demeanour. Cheers 🙏

Hi, I have one 820-00850 A board ... Everything looks ok except it takes only 5V without battery (with battery connected it takes 20v) I've remove UB400 (CD3215C00Z) and one pad was missing (NC_USBC_TB_RESET_L) I've check board view but there is no trace for this exact pad :( do you have any suggestion where should I run wire to repair this pad ? No this IC (UB400) get hot and one USB-C port is not working (I expect that it's because missing pad)

[@iRevive]

The NC in the line name stands for Not Connected. NC pads are not functional and just there as a place holder. You do not need to run a wire. NC pads come off all the time. But they do nothing. You should be fine to just replace the UB400 as is.

@@iRevive is there any difference or can i use CD3215C00, originaly there was CD3215C00Z

How to buy this ic

[@iRevive]

Louis Rossmann sells CD3215 ICs. Here is a direct link to this IC on his stores website. store.rossmanngroup.com/za2-cd3215c00.html

[@MrPnew1]

Typo in the title too iRevive :) 2010

[@iRevive]

Thank you for pointing that out. I must have left that from the last video I did. Fixed now.

As to the argument of long-stream vs. edited video where someone argued against shorter videos, I agree, but for a different reason.
There are only so many hours in a day, and time spent editing is time not spent repairing boards (or resting properly for a day of board repairs the following day). Picturing, in my head, you doing editing while boards are waiting to be fixed is a thought that annoys me - and you already mention you're not getting enough sleep.
You explain stuff so well anyway that I can just have your stream/video running in the background while working and not miss anything, as I can almost picture what you're doing. You don't have oceans of filler in your streams anyway, unlike Rossmann with his political rants and detours or Paul Daniels with his cats and disgusting, repulsive pineapple pizza fetisch. If, like them, you start having actual snacks and dinners during your streams, I could understand, but as is, I don't know who needs an edited version of this.
The rest of my comment is just utter pedantics - grasping at straws for criticism because the repair is near perfection:
The cap you first measured being 9,9 ohm, and later measure with no chip on in the megaohms is perfect diagnostics, but if you're using that as a measuring stick for if something is wrong or not, why not also measure after you put a new chip back on, before powering it on?
IF whatever was shorted was something else directly connected to the CD3215, not the CD3215 itself (but also causing it to fry the CD3215), powering on again with the short still being there might have toasted the new chip and be 9,9 ohms again. Diagnostics-wise it would then help if you saw a before-and-after measurement in ohms, with the new chip on. As is, if this new chip had also (looked) shorted after being plugged in, you might have suspected a dodgy CD3215 from some chinese vendor who used too much heat while pulling it off a donor board.
Even for grasping at straws, it's a thin straw, but since the internals of a CD3215 aren't known, there could be a natural 10-ohm or so path through some parts of them.
(Also, I swear I can see things in your videos more clearly than a year ago.)

Thank you. I am happy to hear you understand my problem with personal time management. It is difficult to repair boards, take care of various administrative tasks, edit videos, and have a life with my wife outside of working. As for your suggestion on measuring the capacitor before and during the repair process, you make a very valid point. I should have measured the cap after the CD3215 was replaced to save myself from blowing the new IC in the event there was a further issue surrounding the chip. This type of criticism helps me become a better technician. Thank you. As for my previous streams, I was using a Dell Optiplex with a core 2 duo processor, so I could only stream at a max of 720p. And even then, I think that was scaled. This current computer has little bit more power so I can push for 1080p with some dropped frame. I may consider upgrading to an entirely updated machine in the future. I am pleased that you enjoy the stream!
