Чтож… Мой мак выдает красный индикатор на CPU B, который не отвечает за температуру а нижний

. Я пробовал поменять местами процессоры А и Б, но индикатор так и остался на Б, я предполагаю что материнская плата завершила свой срок, но хотелось бы надеяться на лучшее. У кого-то есть решение данной проблемы?

Но!

Покупать у Apple очень дорого, использовать переходники не очень хочется.

Transcend производит такие накопители (JetDrive 820, 825, 850, 855).

Внешне они похожи на blade ssd, количество контактов абсолютно одинаковое.

Но по непонятным причинам Transcend про поддержку iMac ничего не говорит.

Пожалуйста, дайте ответ на самый главный вопрос: если я куплю pci-e ssd JetDrive 820, 825, 850, 855, он ПОДОЙДЁТ или НЕТ?

Hello. Please help me finally understand the choice of pci-e ssd. I'm ready to disassemble the iMac and replace it.

But!

It's very expensive to buy from Apple, it's not very desirable to use adapters.

Transcend produces such drives (JetDrive 820, 825, 850, 855).

Outwardly they look like a blade ssd, the number of contacts is exactly the same.

But for some reason, Transcend does not say anything about iMac support.

Please answer the most important question: if I buy a pci-e ssd JetDrive 820, 825, 850, 855, will it PICK or NOT?

в связи с этим я решил заменить матрицу на новую но появилось два вопроса:

- существуют ли в принципе оригинальные матрицы и как их отличить от подделок?

- не появится ли пыль при установке новой матрицы?

для меня это важные вопросы, поскольку занимаюсь цветокоррекцией - для меня крайне важно правильное отображение цветов, и отсутствие пыли на экране.

заранее - спасибо!

English: Stand is not staying in the right position!

Good afternoon! I have a problem! Monitor is not fixed, as if I had not tried to raise up it automatically drops down to the end! stands at home base "leg"!

Can you tell me how can I fix it?

And if I need to remove the screen to get inside to the mount?

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?

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.

I got horizontal lines over the display! During the warranty period they replaced the board ( it blacked out ) and now this is happening. They refused to replace the device saying out of warranty and asked to replace it :-|. They were not even sure that changing the display will fix the issue. I am hesitant to replace the screen as I am better off to buy a new one rather keep repairing the faulty product.

Is there any way to fix it?

Tried
- Reinstall the OS
- External Display = Works fine
- Reseating those 3 cables

Lines kind of flickers, may be some lose cables?

Please help

I have a Mid 2011 Mac Mini (2.5Ghz i5 model A1347) which I bought from the refurb store in 2013.

From mid 2013 to late 2016 it served as a media server, running XBMC/Kodi. Towards the end of that time it started to randomly shut down. I then stopped using it and since then it's been sat in a cupboard.

I was going to wipe it and set it up for my daughter, but I can't get it started. When I try to start it, the power light comes on and I can hear something (I think it's the HDD) and then about one second later it switches off.

Any guidance on troubleshooting this would be much appreciated.

Thanks

So i have late 2013 27 inch iMac. The fan stopped spinning. I installed TG Pro and sure enough it was showing 0rpm.

So i bought a new fan and followed iFixit guide to install it but even the new fan is not working.

What could be the issue here?

I read somewhere that cold solder on fan controller(?) might be the issue. I have attached the image below of the fan connector area. Can anyone help me point out what i could do to fix this without having to go to Apple?

Apple HT shows “there maybe a problem with fan PPF003“
