My 18 month old, MBP M4 Pro screen died. Took it to the ""Genius Bar"" to be told I had a faulty display!! Apparently this is quite a common fault with this model, my "genius" telling me he alone repairs at least four a day!!!!! If you're using this as intended and on a live event or important gig it may be worth having a spare USB C display to get you out of trouble (Command +F1 to switch).

The really annoying thing about the repair was that they wouldn't work on it unless it used the latest iteration of Mac OS, and threatened to wipe my hard drive before basically undoing some nuts and bolts and cables to replace the screen. I had to upgrade there and then to save the hassle of a later install from Time Machine.

This would've cost £623 to fix (I had AppleCare) BUT as I'm in the UK this was considered a 'Consumer Law Repair' which is up to 6 years in this country and also free.

I have a 2" vertical strip on the left side of my screen that all of a sudden turned darker than the rest of my screen. It's tinted darker. I can still see the screen, but it flickers some, and at certain times I can vaguely see the browser's bookmark bar in the tinted section at the top. I can mirror the screen onto my TV, and the tinted strip isn't there. I did some research and think it may be the display cable. Does anyone have a repair guide for something like this?

Mac was inside of suitcase and it was inside of a bag.

Mac boots up,I can hear the chime,but the screen is totally black,not even “light” black. Caps lock light doesn’t work.

I tried SMC,PRAM reset, didn’t work.

Reconnecting screen display by unplugging those two things didn’t work. I used this video

Reconnecting battery didn’t work.

I also tried SMC,PRAM reset while the battery was disconnected and Mac was getting energy from the charger. Didn’t work. I used that video.

What else can I do before changing the screen?I don’t want to swap screen cause it’s expensive.

I’m looking for recommendations for good Apple repair shops experienced in microsoldering on Mac Book Pro logic boards.

The rear of the KB's cable on the older 2010/11 models is striped, 2013-17 is black. 2012 I believe can use the 2013-17 keyboards.

The next day it would no longer power on.

Using a USB-C power meter, it only draws 5.05V at 0.08A and never negotiates a higher voltage.

I have already tried:

Different chargers and cables

Holding the power button

Leaving it plugged in for several hours

Is there anything else I can try before considering motherboard repair?

I assume the battery is dead and the charging circuit doesn't want to charge it due to it being critically low but im looking for alternative answers instead of opening it up for now

33kb Volume only is displayed. Unable to partition or erase.

Attempting to install Catalina on a unit that previously had Catalina installed.

Ignore the other drive that is highlighted as that is my external multi installer drive.

It is the same thing with another SSD except the other drive isn't listed at all, just the base system. Failed drives?

Windows was never installed on either of these drives, this has been confirmed by previous owners.

This is relevant to my other post 3x 64 GB SSD - Q Folder @ Boot

UPDATE: Tried with a Windows installer.

SSD (1) Gave me this:

SSD (2) Gave me this:

After hitting OK it rebooted to the Q folder.

Chap GPT suggests the following.

• SSD power rail missing or unstable
• Corrosion/liquid damage around SSD connector
• Broken SSD PCIe data lines
• Clock/reset signal issue
• PCH communication fault
• SMC-related power gating issue

The “33 KB device” symptom usually means Recovery only sees its own RAM disk or recovery environment, not the actual internal SSD

2. Measure SSD power rails
   You should verify:
3. PP3V3_SSD
4. SSD enable signals
5. PCIe reset

I’ve tried entering DFU mode and it did not work.

There is no sound, and the display does not turn on at all. I had exactly the same issue with a slightly older MacBook, it really seems like this is a systematic issue. Does anyone have an idea if this is true and a possible fix?

This guide is perfect for replacing the keys on this keyboard.

We removed the RAM, Cleaned up, No corrosion found, Re-Balled and installed again. Now all we get is an orange / green light on the charger. It appears that all the power rails are intact with no shorts. Q is why isn't it giving us 3 beeps when RAM isn't being detected / failed RAM chip. What are we looking for to check if each RAM chip is functioning or getting power? @oldturkey03 any insight please?

We initially used this video to diagnose.
