MB pro 13' (2019) Display artifacts

By doing what (which parts replaced)? Which Macbook model and what was the flickering problem exactly?
Was it like split second horizontal distorted pattern on the lower part of the screen that happened couple times in a month without moving or touching the machine (I mean you were not able to reproduce it by touching or moving some parts)?
 
My refurbished 2019 13 2.4/16/512 that I got last week started to have display artifacts yesterday. I'm in the process of shipping it back to Apple.

I did not change anything. It's just stop. But when I was looking how to solve my *battery drain while sleep* problem I did start MB in safe mode and did SMC and PRAM reset. But I'm not sure that it help. It was horizontal lines as on video at 3rd reply of this thread. I can't reproduce them. They was disappear for a several days, then come back then disappear again and since that I did not see them

OK, I see. Thanks for clarifying that. Because I thought you were replying to my question whether someone had their unit serviced and possibly some parts replaced to fix this problem. I think this is really just sw, fw or driver problem and not faulty hw part. Too many peoples with too many generation machines are suffering from it, so hw cause is unlikely.

In my unit it is also exactly the same as in the post with video of it your are referring to.

Of course if someone is experiencing something permanent flash that happens when moving the lid or the machine and if it requires to turn off/on machine to get rid on it, it is then something more serious and likely hw related.

Small update, After my reply I was watching the movie on TV and my MBP was opened. And I track that sometimes, very few times ,my screen was blinked. I called to our local apple service and you know, service guy told me that they know about it and he have the same it his 2017 Mbp without TB. It has started with him from the last 1 or 2 OS updates.

Let’s wait for Catalina?


This is not a HW issue.

(Sorry for my English)
 
Definitely looks more like sw issue. I'd say it is better to sit tight and wait for updates unless someone necessarily want to send their unit abused and kicked around. Not saying that happens to everyone but at least my experience with many different brand service has been that product almost never comes back the same condition (cosmetically) as it was. So I think twice and try to make sure something is really broken before sending my unit for repair.

Those still within return period maybe want to consider return/rebuy for piece of mind but they likely end up with the same problem in new unit.
 
So, i had my display replaced on Saturday. The issue is not fixed. I am booked back in again on Saturday. This will be my 4th repair.

The tech already said if I have to come back they will replace my laptop, so I will be getting a new laptop, hurrah :)

My unit is ready =) it's OK! Totally changed logic board and Touch ID sesor. Testing now :p

Do you mean it works now, or you are still testing it and not sure yet?

Was is random flickering that happened few times a month or constant (how often it happened)?

I've heard this is probably software issue (if it is that randomly and rarely happening type).

I can't say nothing at this moment because im testing it now after repair. It was few times a week. I wrote about it in my 1 msg. I can't understand the reason of it because sometimes they was on "hot" device, sometimes on "cold" .

I saw that picture, and it was more or less what many peoples seem to be suffering from (if it just shows up in split second at the time and not constant pattern), and that is exactly like what I have heard might be just software issue. I heard many different generation machines suffering from it, so another clue it possibly is not hardware related. Of course since they replaced parts in your machine, they definitely seem to believe it was hardware issue but I would not be surprised if they just ended up replacing some parts just in case (I've seen that happening with many other brand devices).

In my unit I've seen exactly the same kind of flickering as in your first post and it happens randomly in my unit, so far maybe once every couple of weeks or so. I've never been able to reproduce it certain way, like changing display angle, or shaking / knocking the machine (to make sure it is not cable issue, or bad soldering or connection).

Hopefully yours is fine now, but I would not hold my breath, so to speak. :)
 
I've been posting this in my other thread and then realize this was here.... i'm on the second unit in 2 weeks and i have this weird artifact flickering.

sometimes it's just a quick flicker, other times it's what the OP posted. What is the situation right now? What do you guys recommend?

Is this software ? hardware? No one knows yet? I'm nervous because i'm approaching that 15 day window... i'm thinking of walking into apple and talking to the manager to extend my return/replacement window.

i would like to point out that i've been able to duplicate the issue more often if i am moving the laptop slightly around, nudging the screen... this is hardware isn't it

Again someone who replaced the machine and still the same issue. Sounds other than hw issue to me.

None of us know for sure. Basically I'm already out of return window, so I definitely just sit tight and wait. I will not bring my machine to service center for being abused and kicked around in case it turns out to be just some sw/fw issue that will be fixed later. I'm too keen to keep my machine in pristine condition cosmetically and my experience with every company (not just Apple) service center has been that machines never come back without some additional marks on them, never.

Hard to say what to do, but I guess trying to extend return window would be good idea. Or if you are overly concerned, then return/refund the unit and wait until issue is solved (in case it ever will be announced. More likely it will be just quietly fixed in upcoming updates) and then rebuy.

Yeah it could, but it can be (most like is, I suspect) from True Tone and / or auto brightness setting, it can get light at the different angle or something to cause it change some setting and causing that. Again pure assumption on my part, but I'm pretty sure that is it.
 
I think, that Apple are in, because first of all it’s a business and, they will not do anything without reasons. They don’t call me or asked any questions. Just took my unit, diagnostic and change ( the result of diagnostic!??? ) dark theme....

I think you don’t need to panic... one year warranty will solve any problem .. ps we have 14 days window to refund and return)
 
The more i use the laptop and notice the flickering the more i think it is some type of connection wire, something is loose....



EDIT: but then it happens when i'm barely touching the laptop... sigh, i dunno this sucks.

Yes it’s may be, because when I shocked table, or moved MacBook accidentally sometimes **** happens but when I try to do it specially, shock or move or open:close display never seen it

I think loose connector is very unlikely as pretty much all are secured with clip + screws to keep them in place. Also if it was loose connector, then we would see different degree of this problem (not all having horizontal flicker on the bottom third of the picture) and very likely it could have been induced by shaking or tapping the machine.

Then again, if it was just a loose connection wire, why they replaced mainboard in SergeySeregin's machine? I bet they just did that just in case. Or if it is a fw issue maybe they have parts with new fw installed or some other reason they rather do it that way at this time. But I still bet they just changed that part just in case. I don't think they much spend time testing the machine after replacing parts other than basic diagnostic / burn in test run. Good example of that is you see peoples sometimes with certain screen quality problem getting their screen replaced and still get the same problem with the new screen. Why would they return it that way if they saw the same problem with the new part, hence I suspect they do not much test them after installing new part. They just assume it is now ok, as the part has been replaced.

Anyway, I still want to believe this is software, firmware or driver issue.

I mean how often you saw them before repair? Did it ever work for 1 or 2 days without doing it?
