The dreaded TouchBar Flicker.

[Jackbequickly]

I, for one, am glad Apple got rid of the touchbar. Just recently purchased the 2021 MBP 16” M1 Pro and before I did, I made sure the touch bar was gone. I know some liked and some did not but I prefer the traditional keyboard for my use.

Another update, mic hole under the touch bar appears to be for keyboard noise cancellation. On th A2251 facetime call keyboard noise cancellation doesn't work as well compared to my M1 MBP (I think same touch bar, same mic design). Possibilities are

- Didn't clean out the mic hole as well as necessary
- Original apple touch bar had a cutout on the touch bar sticky tape where the mic hole is
- Mic got damaged by IPA/glue during touch bar replacement
- Aftermarket touchbar transmits more keyboard sounds? (it does seem dimmer than my M1)
- M1 keyboard noise cancellation works better than A2251?

Anyone else with similar experience after touchbar replacement?

My situation is more awful than you all :\.
I'm an Egyptian software developer.
- in 2018 I bought MB Pro 16" 512GB 32GB for 60k EGP (3000$ at that time).
- after 11 months in 2019 I upgraded from Mojave to Catalina and then it didn't turn on again and did all kinds of solutions but no clue. Likely at that timing, I had 1 month remaining in the warranty. I went to the official apple reseller and they changed the board in Apple UAE for free and I received it again after 1 month.
- 8 months ago (Jan 2022) touch bar started to flicker.
- 5 months ago (Jun. 2022) it dead again after a battery drain to 0%. I went to the official apple reseller he told me that I'm out of the warranty and it needs a new logic board, new keyboard, new touch bar & new battery for 50k EGP so its better to you to buy the new M1 14" for 45k EGP . I was about to lose my job and all my life went dark (I use it 14h daily!). I went to a famous shop in Cairo that can fix any Apple device called Trojan Stores. They took it for 1 month and don't know what they did but they told me that they have fixed a thunderbolt IC and replaced the battery all for 8k.
- at the same current year we are facing stagflation and inflation and our currency dropped 40% .. The new M1 Pro 512GB now for 63k and 16" 512GB for 73k while if I sold this 2018 Intel i7 one it worth 13k (562$) here 😂

Uh, that's truly brutal. No need for further explanation, I feel you!

You seem to know what you're talking about. 😄 I have the same Touch Bar issue, where currently it will crash after sleep (or sometime overnight) Currently I've been just shutting the thing down and that seems to be solving it. Do you think this is a long term solution? I'm docked 99% of the time so have the luxury of not needing to open or close the lid. I'm more concerned with my files, and whether the logic board or something larger than the Touch Bar is failing. Don't need the Touch Bar to function. Based on your experiments, it sounds like I might be good to go?

Evening

Just wanted to add my experiences of this pos touchbar flicker bs.

Mid-2020 13" MBP i7/32Gb/1Tb.

It cost £2,600 new!

It's less than three years old and the touchbar's stuck in disco mode. I'm being told the entire mainboard needs replacing at close to £1,000

This model isn't covered by the keyboard repair program.

What really f's me off is that this particular laptop couldn't have been better looked after. It's spent its entire life indoors and shut connected to an external monitor.

I appreciate people's suggestions to buy a new one or temproary software fixes but that's hardly the point.

This is clearly a design flaw and Apple should repair it foc.

I noticed above somebody attenpted a self-repair. I will investigate.

Every owner affected should email directly to TCook… i will do eventually when my i9 16incher will start flicker

I have just days before my two year government backed Apple warranty expires and am taking mine in. It's obviously got something to do with the light sensor in my case because it only happens in low light. Disabling the light sensor is not an option for me, just a bandaid. Want it fixed so I can sell my M1 MBP and get a more powerful Mac. I will miss the Touch Bar, but I won't miss the blinding disco. I prefer working in very low light conditions so it really is blinding.

 

[touchbarflicker]

Has anyone had the Touch Bar flicker with the M1 Pros as of yet??

Yes it happened on my 2020 M1 Pro although I suspect it's a hardware issue. I tried turning off the touchbar in settings, as well as force quitting it from activity monitor, but although it successfully turns off the touchbar it still flashes a blinding white rectangle on the right half.

24 end if
25 return 1
26 end idle

Keeps the TouchBar active, so it doesn’t go off. To be exact, it restarts TouchBar every time it goes off therfor stopping the flicker.

Apple will want to replace the top case & Logic Board which is utter BS as the TouchBar can be replaced in isolation, admittedly is a royal PIA do so as it's typically glued in place

Replacing 2019 MBP with touchbar. This one has a single microphone below the touch bar. Mic needs to be peeled back before using ISO to remove the touchbar to not destroy it. Here is the hole below the touchbar.



Note depending on MBP model, mic is in different locations.

 

[howardc64]

Fixed another one. This one had an overcooked inductor to the touchbar touch sensor power rail.

MBP A1989 Touch Bar sometime sluggish touch response - Badcaps

Had flickering touch bar display. Replaced. Now have an intermittent touch reponsiveness. It generally works but sometimes a press would not respond and need to touch again... sometimes more than 1-2x. Generally happens when trying to go faster on the touch bar and seem more common in certain...

www.badcaps.net

Also removed the keyboard click mic below touchbar this time prior to removing it (ISO will destroy it if not removed)

 

[Pedro147]

Good call on removing the mic before attacking the touchbar. Sometimes the small hole gets covered up by the adhesive strip on the replacement touchbar too. It's an abomination of an idea and I'm glad that Apple dropped it eventually.

 

[howardc64]

BTW on A1989, the touch sensor connector on logic board is 2 columns of 11pins with a rectangular depression on top and bottom to guide in the flex connector. The touch bar touch sensor connector on flex has 2 columns of 13pins. It snaps in nicely with the guides. My aftermarket one didn't snap in nicely. Under magnification, 1 guide tab is missing and another appear smashed. It is easy to get 1 row off. Don't know if this is the cause of the burnt power rail but just noting great care is required to connect this connector especially from aftermarket touch bars.

If 1 row off, touch bar will not come on. Happened to me a few times until I checked the alignment carefully.

I have a MBP A1989 with the touch bar flicker. Normally, I would attempt a repair myself, but this time I still had an aftermarket warranty, so I thought I would use it.

What a mistake! They had my MBP for 1 month and couldn't fix the issue. They attempted to replace the whole top case, rather than the touch bar, but after several attempts, they gave up and returned it to me.

In fact, it came back in worse shape. The flicker is still there, but now the right fan is also stuck on max speed. RPM readings are normal, all sensors look good in Stats. I checked all cables and it looks good. I carefully swapped the fans to test, but it is not the fan as the problem stays on the right side.

Doing some research, I discovered this can be the keyboard cable, so I ordered a new one. I also learned that if the fan speed signal is missing, the fan will default to max speed.

And now I find when the MBP reaches 100% charge, it will beep every so often, as if I had reconnected the charger. /sigh

Anyway, the reason for my post, should I bother replacing the touch bar if this MBP is having other issues? I fear the "repair shop" damaged the logic board. I really wish I never took it to them, but I thought I'd save myself hours of work.

Why dont you return mn to repairer and claim damage?

I wouldn't trust them to touch it again. They're aware of the problems, but not accepting the blame. I'd have to sue and I'm not sure it's worth the effort for a 5 year old laptop.

Instead, I called the warranty company who is going to pay me out the maximum repair value. It's enough that I'm satisfied with the outcome, but not enough for a new MBP.

So now I have a damaged MBP and I can either fix it or not. I don't mind spending the time on it, but it might not make financial sense if it's the logic board.

Ok, i see. Heh i got last gen mb pro 16 intel, it is 2.5 years ild, curious when shoul i expect to start flicker

 

[Transient77]

The OLED display flex has a short piece with a connector that connects to the logic board. This short piece could be the failure source. If this is the only failure area, it is super easy to replace instead of the whole touch bar (display, logic board don't need to come out, touch bar stays glued to the case) Perhaps someone can try this experiment in the future. Its part A in the last pic

I didn't see this question answered anywhere and I wondered the same thing. I tried replacing only the cable and it did not help.

To further experiment, I next tried replacing the touch bar and using the original short flex cable. This worked.

As such, in my case anyway, the problem was definitely with the touch bar and not the short flex cable.
