MacBook Pro 15" Retina (Mid 2012-Mid 2015) Right Speaker

Mon problème

Speakers were making a lot of screeching noise at anything but very low volume

Ma solution

The guide was excellent - I was super afraid I will damage something as it's the first time I open a laptop in my life (I assmbled PCs in the past but the last time was 15 years ago

Mon conseil

- ensure all cable are ABOVE the logic broad before you put it back. I had to lift it a couple of times as I kept forgetting the cables underneath it.

- be patient. If an item is not getting removed or not being inserted with ease then you're probably doing it wrong. Or something is obstructing it. Avoid the temptation due to frustration to force anything in or out at.

- arrange your screws you remove on an A3 paper and write underneath it the item it belongs.

- its ok if it takes a long time. Better safe than sorry. It took me 3h30min to finish it from start to finish.

Mon problème

The old speaker was blown. Sounded terrible.

Ma solution

It went well.

I have designed and worked on electronic devices all my life so I think it is with some authority that I can say this is not a simple job. If you are all thumbs do not try it, but if you have steady hands and are not prone to forcing things and can work VERY methodically then it is very doable.

I replaced the SSD at the same time.

Mon conseil

Because I am such a perfectionist, after I put everything but the back cover back together, I checked to see I had all the cables re-connected. One connector was missing a cable! Agggh. I took the entire thing back apart to find the elusive connector that I thought had accidentally be allowed to be covered by the main pcb. Well stupid me. I there was no connector. There is one unused connector on the motherboard that I assume is used by Apple for Jtag testing or programming of onboard devices. I was so annoyed at myself.
