MacBook Air 11" Early 2015: No Internal or External Display Issue

Sat, 11 Jul 2026 04:01:52 -0700

Have a 2015 A1465 here (820-00164) that chimes / boots but there is no display at all. We have tested with another known display assembly & on external displays but still nothing. From what we can see we are getting readings from the outputs, but nothing, just a black un lit screen. GPU failure I thought gets a white screen. The fan is also at high speed. What can be? (I do believe that the technician has replaced the SMC 2x already).

MacBook Pro 13" Retina Display Early 2015: Thin 1 pixel Intermittent Horizontal Line on Screen

Sat, 11 Jul 2026 05:15:13 -0700

We have 2 A1502 units here (2013 & 2015) that both have a tiny 1 pixel vertical lines on the display, it is sometimes there at boot, then they go away, and sometimes appears after a period of time (On both units). (2013 1 line) (2015 4 lines at equal distance apart). The lines do appear to show at the same point each time. We have cleaned the connections and all appears super clean. Is this a sign of a faulty LCD or something else. The next step I guess would be to swap out the LVDS cables as we haven't as yet tested that way. Testing with other displays & externally there is no issue at all, displays tested on other units and the issue persists so it is 100% something in the assembly, so each display likely is suffering the same or very similar problem. We have reset SMC / PRAM to. no avail and both units are using a clean installed stock SSD. Or is there something simple I may have missed? Or are we facing early signs of a failing T-Con or LCD?

MacBook Pro 15" Retina Display Mid 2014: Touchpad not found after replacement

Fri, 10 Jul 2026 16:58:03 -0700

Hi all -

Original symptoms were short battery life and touchpad physical clicking not working. I bought a replacement battery and touchpad.

Battery was definitely bulging and putting pressure on the touchpad. I swapped out both and when booted back up - no mouse movement or clicking at all from the touchpad. External mouse works fine, so I went into system preferences and then Touchpad. It said "Touchpad not detected" or something along those lines and had a spinning circle indicating that it was searching for bluetooth touchpads.

So I opened it back up and swapped in the original touchpad - mouse movement but no clicking. But still, system preferences says it doesn't detect a touchpad (I was hoping to at least turn on tap to click.)

So, what am I missing? Is there some extra step to set up the touchpad with the OS? Does the lack of movement on the replacement pad mean that it's DOA?

Thanks for any help!

Apple LED Cinema Display 27": PLEASE HELP! Problem getting stand back into the display.

Thu, 09 Jul 2026 21:46:56 -0700

Hello! I have an Apple Cinema Display and we had to remove the stand for transport when moving. Long story, doesn't matter. Anyway! We removed the stand, no problem. I slipped a credit card in, click, the hinge came out and we unscrewed it, all good.

I went to put the stand back on, and the hinge is back inside the monitor. Must have happened while in transport. I cannot seem to get it back out. I've tried a card at a 45 degree angle while using a siding removal tool to lift the hinge from the center button and it will only come up flush, not come all the way out, AND it requires a fair amount of pull to get it to come that far. Not enough to break anything, but a bit of force.

Everything I've read said that I should be able to insert a card bent with a 45° angle and just hit the little latch and bring the hinge out again but I just cannot seem to make it work. Wondering if the community has any ideas. My last ditch would be to actually remove the glass and take apart the monitor to release the hinge and I don't wanna have to go through all that if possible.

I uploaded a video that shows what I mean here: https://youtube.com/shorts/Jt1xTgI1XdY?f...

Thanks for any help!

MacBook Pro 16" 2021: Logic board swap? MacBook Pro 16" A2485

Wed, 08 Jul 2026 12:08:17 -0700

Hi, is it possible to swap an M1 Pro logic board into another identical model without issue?

I have a 16" Macbook Pro 2021 (A2485) that has a cracked screen but I am able to buy a complete identical model laptop 'skeleton' (minus its original logic board) for less than the price of the repair at Apple.

If I transfer the logic board and Touch ID from my 'working laptop' with the cracked display, into the donor laptop shell, will everything work as normal or will I come up against a few issues?

Thanks!

MacBook Pro 13" Two Thunderbolt Ports Late 2020: M1 MacBook Pro display issue: Green horizontal lines slowly spreading

Tue, 07 Jul 2026 19:35:48 -0700

Hi everyone,

I’m having a strange issue with my MacBook Pro display, and I’m hoping someone can help.

A few weeks ago, I noticed a couple of thin green horizontal lines starting at the bottom of the screen. Since then, more colored lines (green, pink, and other colors) have gradually appeared, and the number of lines keeps increasing day by day. The issue seems to be spreading upward from the bottom edge.

The strange part is that my MacBook has never been dropped, the display has never been hit or pressed, and I’ve never accidentally closed the lid with an object inside. It has always been handled very carefully.

Here are a few details:

The lines are only on the built-in display.
They started from the bottom and are slowly increasing over time.
There was no single event that caused the problem.
Restarting the Mac doesn’t fix it.

I’ve attached a photo of the display.

Has anyone experienced something similar?

Is this likely a failing LCD panel, display flex cable, or display controller issue?
Is there anything I can try before replacing the entire display?
Could this happen without any physical damage?

Any advice or suggestions would be greatly appreciated. Thank you!

MacBook Pro 13" Retina Display Early 2015: MacBook won't power on after battery replacement

Tue, 07 Jul 2026 19:34:03 -0700

I replaced my battery following the ifixit instructions, and it seemed to work perfectly for the first week. Then out of nowhere, it just stopped turning on. At first, the charger light wasn't lighting up either, but eventually it was on green, but still wouldn't turn on. After disconnecting and reconnecting the battery again, the light is orange, but it still won't power on. I tried troubleshooting with the ifixit bot, and I'm stuck. Please help.

MacBook Pro 16" 2019: Leftmost 512 pixels not displaying

Tue, 07 Jul 2026 06:23:08 -0700

I got this machine cheapish as the original display was smashed. The full image could be seen though. I had a spare here and it works fine except the leftmost 512 pixels which is very telling. That’s exactly 1/6 of the panel. There’s no physical damage to the display but I have noticed the lugs holding the metal covers over the ribbons down on the tcon have failed only on the innermost lugs. I suspect it’s been badly flexed at some point. My question is, could there be a tcon issue here? It feels more like that than a damaged lcd or flex gate. Never seen a flex gate lcd like this.

MacBook Pro 15" Unibody Late 2011: Command key and zero (0) not working

Tue, 07 Jul 2026 02:40:28 -0700

I had an issue with the Command key and 0 not working, started intermittently. Then qaz and delete stopped working that too started intermittently. So I ordered a new top case. After a lot of screws and picking things apart and putting it back together again, I have a new keyboard. The problem is that Command and 0 is still only working intermittently. If I push both Commands and zero at the same time it usually get them going again. The question is what could now be the issue. The Command key does not work at startup either, so it most likely isn't a software deal. haven't had any issues with qaz. Appreciate any ideas or suggestions.

Macbook Pro 16" 2023: Horizontal lines and flickering display issue

Mon, 06 Jul 2026 15:05:53 -0700

About a week ago these visual issues have started, which I have assumed were linked to the flex cable that goes into the display assembly itself, making it impossible to fix.

The issue is triggered either by pressing the plastic bottom bezel at the left corner, or by moving the orientation of the screen.

I put my laptop for sale on a local marketplace, and someone called today saying the same happened to his 16" M1 Pro. He told me a repair shop has successfully repaired it by replacing a ribbon cable hidden behind the said plastic bezel strip, and the repair cost him very little money.

Does anyone have any idea about what exactly could've went bad so I can explain it to technicians that would attempt a repair for the laptop?

So far, I've just been quoted a full display assembly replacement costing from 800 to 1000€, which isn't an option. Thanks

- Hard to see on camera, but that region of the chin bezel > display seems to have kind of a bloated/warping effect.

MacBook Pro 15" Retina Display Mid 2015: Speaker replacement troubleshooting assembly

Mon, 06 Jul 2026 13:05:08 -0700

Hi,
I just replaced both of my speakers on my MacBook pro 2015 (a1398). Powered on the mac and both had a muffled sound. I shut down, disconnected the battery and then reconnected both speakers again. The right one is now working just fine, but the problem persisted in the left one. I kept trying to reconnect it better. but in my last attempt the black frame (socket) that is holding it securely with the pins fall off. Is this repairable? I was sure it was just a frame to keep it in place, but it also have a black floor so I am wondering where to go from here. Any assistance will be much appreciated.

Mac Mini Late 2012: Mac Mini not booting, white led blinks, fan spins briefly, no chime

Sat, 04 Jul 2026 16:37:39 -0700

I'm having an issue with this model (intel i5, 4GB DDR3 ram), where it starts up, white led turns on for a while, fan spins up briefly but the mac mini does not turn on. This process repeats forever.

I've removed the power supply and I'm measuring the voltage. With no load, they all read 11.88V (any of the right pins with any of the left pins). Then I press the switch on button, all pins go down a little (like 11.82V) but the rightmost left pin + any of the right pins read ~9.22 for one second, they go up to 11.88V, then down again, then up and down, etc.

In a picture I've found on the internet, this "rightmost left pin" is marked as ground.

The point is: is this behavior right? Should the ground pin have 12V, 0V, or what?

Ps.: I'm from Brazil and English is not my first language.

Red: negative pins
yellow: neutral (? maybe not) pin
blue: positive

PSU details

Model details

Voltage reading between any one positive and one negative pin

Voltage between neutral and any positive pin when computer is trying to boot up. The reading fluctuates between 11.8V and 9.2V consistently - i.e., when trying to boot up voltage goes down, fan spins briefly, stop, voltage goes up, rinse and repeat

Reading between any negative pin and neutral pin when the process described above is happening. Voltage goes from zero to 2.5V at the same time the above process is going from 11.8V to 9.2V

Demonstration of how I'm measuring things. In this example, one negative pin (black probe, left), one positive pin (red probe, right)

mobo for reference (side 1)

mobo for reference (side 2)

Extra information: all tests were done with RAM installed and with no RAM installed, same results. Also, sometimes, for no clear reason (at least to me), after probing the mobo randomly with my multimeter (hoping some fairy could tell me what's wrong :-D ), the mini boots up - I hear the chime. But after turning it off and then on again, the miracle stops working.
