仕方が無いので、自分でロジックボードの交換をしたいのですが、どこでロジックボードを入手することが出来ますか？

中古でも販売していることを見かけることがありませんので

入手手段を教えて頂けますと幸いです。

Currently I am using imac 5K mid 2017, but since usb - c failed, I brought it to an APPLE authorized service provider, but I was refused repair.

Since there is no choice, I want to replace the logic board by myself, where can I get a logic board?

Because I do not see what I sell in second hand

It would be greatly appreciated if you could tell me how to obtain it.

エアダスターでのホコリ除去なども試してみました。

元々このタイプの古いMacBookProはリコール対象だったことを知らず、Appleでキーボードの無償修理があったようですが、ちょうど調子が悪くなったタイミングがその期限の過ぎた後で対応できませんとのこと。

もし詳しい方で何か対処法をご存知の方がおられましたら、ご教示いただけるとありがたいです。

2011年9月にApple StoreでMacBook Airを新品で購入しました。そしてトラックパッドが、2012年9月に反応しなくなったため、Appleで交換しました。この修理以来、問題は発生していません。

今朝は問題なく動作していたのに、今日の夕方、キーボードとトラックパッドが全く反応しなくなりました。キーボードで動作するキーは、電源ボタンだけです。システム設定では、トラックパッドが接続されていることすら認識されなくなりました。

インターネットのフォーラムで、MacBook Proで同じような問題を抱えた人がいて、それはバッテリーの下にあるリボンケーブルが緩んでいたからだという話を読んだことがあります。しかし、この問題がMacBook Airモデルでも発生しているという情報は見当たりません。もしかしてこれも同じ問題でしょうか？

A couple of hours later when he went to turn the Macbook and that's where he first noticed the problem with the backlight. He says that when he first turned it on, the screen was very dim, but he was able to make out a dialog box on MacOS. Then he said it flickered and went completely dim.

When he gave it to me, the screen was completely dark. However, by shinning a light through the Apple logo, I was able to see the MacOS desktop and confirm it was the backlight that was not-functioning and not the LCD. I connected his laptop to an external monitor and was able to confirm that everything else was working fine.

At that point, my initial instinct was to just replace the display. I found a couple of eBay listings of Macbook Air displays that came with the full display housing. However, in the course of my research, I've read a lot of support threads identifying the Fuse on the mainboard of the Mac as the reason why backlights on the MBA might fail.

Here's a picture of the (what I think is the) fuse on the mainboard:

My Question: How do I know which is the right solution? How do I know if the Fuse is blown or not? Will buying the display off eBay solve the problem regardless? Or will I end up wasting money if it turns out to be a problem with the Fuse?

I ended up being successful, however in attempting to loosen the logic board screw to allow room to to seat the hard drive as the instructions indicated, the screw was so tight I stripped the screw. After quite a lot of struggle I seemed to get the drive seated and it is functioning.

Is there a way to loosen the screw for any future issues?

Today's problem: Diagnostics I received a 2015 13" Macbook Air and the customers problem was that the computer randomly shut off while his daughter was watching a youtube video and then it would not power back on after being plugged in.

They attempted to fix it themselves just by those steps i.e. (unplugging it and discharging and then plugging it in again to see if it powers on.

So far I have tried unplugging the battery from the logic board and powering on to see if the battery was the problem at hand. It still didn't power on. So my only thought is the IO port is bad and that needs replacing, I came here to see if anyone thinks that would be my best next step or if any of you had any advice for me on this project.

A friend of mine who does board repairs/ micro soldering suggested it might be the smc chip has lost its touch.

It came with a Core i5 2400s which is a 65W TDP. The Xeon E3-1280 is 69W. So has anyone tried this before would it work?

I replaced the power supply but no luck (ebay working pull). I am considering replacing the power button next.

It is a 27" 3.4 i7 with 32gb ram and 2gb Vram. Nothing happens when the start button is pressed. It stopped working in February. There were a few crashing that seemed to be related to connecting to wifi before it stopped working.

▪︎are start buttons known for going out?

I'm going to pull the drive and put it in a laptop for the time being: Look at crash report.

Case is still open: monitor is attached but only taped close.

Also if this does start can it run off an external monitor without the screen attached?

It might be easier to work on that way.

Thanks for any help.

(The right speaker is unplugged, I just decided not to remove it.)

Edit: I ordered a replacement PSU and got the same result- a buzzing noise with only LED 1 working. I narrowed down the buzzing to near the top-right of the PSU. Turns out, the buzzing only happens when the computer is attempting to turn on (i.e. after I hold the power button for a few seconds). It stops if I hold the power button for a second or two while it's buzzing. When I remove the PSU data cable, the buzzing I had been hearing stops and is replaces by a higher-pitched buzzing sound that isn't affected by power button presses. (LED 1 still works without the cable, as expected.) I tested each wire in the PSU data cable, and they're all working. I'm thoroughly stumped now.

Hi everyone,

I'd like to get the community's feedback regarding software-based guides on iFixit, specifically basic operating system navigation guides like "How to do a power option on a Mac."

Since iFixit's primary mission focuses on physical hardware repair, I wanted to ask where the community draws the line for software content. Are basic OS navigation guides helpful and appropriate for the platform, or should software guides be reserved for tasks directly tied to hardware troubleshooting and repair?

Thanks for your input!

Then it started turning off every 30 seconds, same thing closing display and opening again fixed it. At this point, connecting to an external monitor worked fine. So on the external monitor I could use it like regular (with mirrored or extended screen).

Then I restarted, tried a bunch of things on the https://support.apple.com/en-ca/HT210905 and https://www.macbookproslow.com/fix-black....

I never got into safe mode or knew if things were working, but I tried all the keyboard combinations. Late into the night, it started working and then I used the Macbook regularly, I went to sleep happy that it was fixed.

Now I woke up and the screen is not working at all, not even showing the apple logo which it was last night. Also, it's not working on external monitor either. I can still see the external monitor and the mouse but it's a black background. The backlight is working and the keys and everything seem fine.

Very frustrating and I'm not sure what to do :(
