Thank you so much Louis you are the best. I had one case of A2179 with no shorts on none of the two CD3217. The current draw was 0.312A at 5V and boot looping. I replaced the EEPROM for the second chip and for my surprise i got the 20V on the connector of that IC. Then i replaced the another IC and EUREKA! both connectors were getting the 20V. Your video was a great base to do the analysis and troubleshooting. Thanks a lot bro , THUMBS UP :D

I enjoy your board repair videos. If somehow your repair business tanked (highly unlikely I know) you certainly would be an excellent educator. I have had a formal education in electronics and I must say that I have heard very few people get a point across as succinctly as you. Today's video is one of the better examples of this. Visual inspection is always a good first step in the repair process. But what if everything looks good as in this case. It's critical to develop that logical thought process that leads you in the right direction as quickly as possible. Your explanation of how and why you arrived at your diagnostic conclusion today was clear and forthright and easy to understand by most of the people viewing this video. Keep up the excellent work! I'll figure out how to give you $20.00 Cdn. (about $14.00 US - yeah I know it sucks) as a bit of a thanks for the good work you do in your business and on KZbin.🙂 Like your many kitty videos as well.😺

There have been times in the past when Boeing or Airbus(don't remember which one) engineers were debugging and writing patches when inside a plane mid-flight because the bug only happened during specific conditions. I’m gonna bet now that Apple engineers design those boards on a windows pc, and that’s not only because there is no decent EDA on Mac.

@@conkerkh you'll agree that they were doing it in test flight, not in an already released product... while Apple release its faulty product then "care" about the problems... by saying the suicidal capacitor was water damage, for example ;p

[@markconger8049]

What caused the ROM chip to die? Does replacing that chip mean it won’t fail again? Or is a test period after repair needed?

[@eldonad]

Well, a rom chip normally isn't exactly a weak component by electronic standards... If there was a bigger problem on the board that caused this chip to fail, my guess is that it would have fried more than one component, and since replacing the chip resolved the problem, it is a reasonable assumption to say that the chip failed by itself (and because it's an apple product, obviously). Now, the computer probably is tested offscreen, and in the case of failure soon after release to the customer, if the problem is directly related to the previous repair, I guess Louis will fix it again with a discount, or something like that. Not sure though...

[@alifasli7221]

Hi Louis, I have also an issue with an a1706 and have a question, when measuring with amp meter only 5v and amp varies between 0.13 and 0.25 amp pp3v3 G3H is present and ppbus main rail also but doesn't get 20V and obviously doesn't charge too and to me the four cd3215 looks all fine (usbc ports doing all the same thing, no anomalities). do you have any suggestion. the only visual thing I noticed is that C3208 looks a bit burned but seems to work fine -, it is not shorted and I am measuring 3v at that cap please any suggestion would be very welcome! thanks in advance!

[@MikeK-ye8lu]

Have the same issue. May I just buy a new SPI flash from Mouser or does it require some Apple specific data?

[@aaaa1111muffin]

You would probably need the data. If you're working on an A1706 like this one, then you could probably just pull the data from the second ROM, copy it, and flash it onto your new ROM in the same way that you would if you were resetting the firmware ROM on an older machine.

[@VictorRamirez214]

Hi Louis - big fan. I sent in my macbook last year to have fixed and I donated to have it done live on stream. Thank you for accommodating me. I have a question unrelated to repair or macbooks. What is the editing technique that you and other youtubers/facebook creators are using to frontload a funny/interesting part at the beginning of a video that you will later see in the video with context. For this particular video, you talked about your hair giving the middle finger around 14.5 mins in, but was also at the beginning of the video. Is there a name for this trend? Thanks so much.

[@markdove5930]

So I have a stupid question how many watts does a laptop charger pull from an outlet if the laptop is off? It's an 120w charger and the. Battery is only 3 batteries in series(asus x550vx ) it takes 2h to charge.

[@iamblaineful]

When you plug something in to an outlet, even when it's not connected to your laptop, it has a parasitic draw, often between 5mA and 50mA to run the components inside the charger or whatever device even if they are not outputting Watts to your laptop or the thing is switched on, what ever the thing is that was plugged in. It's referred to as quiescent current, and the design of rectifiers (converting AC to DC current) is inefficient, thus leaking power when doing nothing. So in an ugly case of using 30mA of current, it's drawing 3.6Watts doing nothing.

O' Mighty one I need some advice.. I have a MacBook Pro 2018 A1990 that no longer switches on or charges. After plugging in a USB meter it reads 19.9volts & the amps slowly creep up to about 0.87amp & then cycle back to the beginning. If I take disconnect the battery I see it drawing 19.9 volts again but hardly any amps, somewhere around 0.01 - 0.02 Any suggestions on what I should look for? I have removed the board and I see no water damage nor do I see anything that looks suspicious so this one has me stumped! Thanks Lewis. Dean.
