MacBook Pro :: Flickering Screen And Loud Alarming Sound
Apr 16, 2012
Hey,
I have a late 2011 MacbBook Pro with Lion. Sometimes my Mac gets vertical flickering bands almong with a really loud alam/emergency sound. Since I am in an office with svereral people, I have to swith it off by using the power button. I upgraded my RAM to 8GB (did it my self)... but there dosen't seem to be a problem with it since it says OK in the System report. Can someone please tell me what the problem might be?
Sincerely,
Johannes

I just bought my MacBook Pro last week. When I power it up, it makes a loud noise for about a second and a half. I think it's the hard drive starting up or the disc drive. I'm not sure which one, but it's pretty loud, so I was just wondering if anyone else noticed this and if it is normal.

I've had problems with my Mac for a while now. First of all, it indicated ram problems with 2 beeps. I later fixed this by moving and changing around modules. It was solved, but now a new problem. The Mac seems to turn on, making its iconic sound for startup, but the screen remains black. After about a half to one minute, the fans go crazy and I have to shut it off. I've tried a few things like holding shift or alt, but that doesn't work as it doesn't even display a white screen.
I need to know what to do and I don't really have the time to buy new parts right now. I'm really a windows based pc fixer by the way so I'm new to fixing macs.

Has anyone noticed a very slight flicker on their new MBPs? I have a new 13" and, every so often, the screen brightness dims and then brightens very quickly (happens in less than a second).The option for auto-adjusting the screen brightness is off so it's not that particular function.It's most noticeable on all-white backgrounds both on AC and battery power. Hard drive access doesn't seem to coincide with the dimming.

I've had the new macbook air just two days now. Turned it on this morning, used it for like 5 minutes and the screen just started flickering, and the whole machine just froze on me! Had to do a system reset, but I'm a little concerned after spending over a grand on this macbook! Has anyone else experienced this? I'm actually thinking about returning the machine..

When I click on the built-in mouse (whatever it's called), it's a lot louder/snappier sounding and feeling - makes more of a loud clicking sound - then my old Powerbook G4 did. Might I have got one that's a little out of whack or are they all that way? If it's normal, why so "clicky?" These days aren't they able to make things softer/quieter? I also noticed how sharp one of the corners is in the area where the latch (or lack of) is...that center area where you lift up the lid. I like that much better than the old one but does anyone else have the problem of a corner being too sharp?

few loud clicks when closing the lid of a MBP 13" slowly, mostly when its like in a 45 degree angle (the lid compared to the bottom)? Really creeps me out sometimes. Edit: sorry about duplicate thread, forum didnt seem to respond at first.

My screen just started to occasionally have a flicker of a white line show up...It doesn't happen that often, should i worry? Is it worth taking it into apple? (Under warranty still) Since its not consistent i wont necessarily be able to show them what its doing..

I was browsing a webpage with Safari when suddenly this really loud screeching sound came from my Macbook Air. I am not talking about the small clicks the HD seems to be doing once in a while. This was a very loud screeching sound, like someone cutting glass with a diamond. I didn't have any other programs on and my speakers were off. The sound lasted for about 2 seconds and got me very scared. I immediately checked the temperatures and fanspeeds but they were all normal (CPU around 45 celcius and fan about 2500 rpm). Now I'm afraid that it was my HD and it will fail on me sooner or later. Everything seems to be work normally now but I already sent all my important documents to another computer.

I recently purchased a 13" 2.26 stock macbook. It's perfect, screen is good (no scrolling issues or purple blues) with no dead pixels, no slanted keys, and no scratches.
I updated the firmware that addresses the SATA 1.5 issue. After the update, I reset PRAM. I held down the buttons till I heard the second or third startup bong.
Here is where it gets funny.
Now, when I reboot or start up my computer, the start up noise is loud. Even with headphones plugged in and also the volume turned to its lowest setting (even with volume turned off). Eventually, to control the startup noise, I had to install the startupsound program in my system prefs as mentioned on other threads and that has seemed to control the startup sound.
I was wondering, if by resetting the PRAM if I have harmed my computer in any way. Should I be worried about deeper issues with my computer since the startup sound was not previously being affected by reducing the volume to zero with headphones plugged in?

I want to tighten the touchpad so it doesn't sound so loud whenever I click on it. But I can't find the correct size allen key for the battery screw. Does anyone here know what is the exact size for the screw for the battery and what type of screw driver to adjust on the touchpad? I know I can use a flat head screw driver, the main part is to get the battery out of the way.

It happens when the MBP wakes up from sleep. The longer it sleeps, the louder it's. Listen for it after the 1st 10 second.

My macbook pro has never made weird sounds. It is 2 and a half years old. It has been dropped twice, but not recently at all. Upper left side of macbook pro made very loud scratching sound as I opened it from sleep. It only did it when I had the laptop at a certain angle. It is still doing it. Im currently backing everything up to an external hard drive. I'm very worried. It was very loud, not the fan, not the usual disc slot movement, not the speakers.

First I wasn't quite sure about the issue, but sometimes I thought my MBA display was flickering. Then I found this thread

Does your screen flicker too, when you watch this pattern ?

My white Macbook, the one i'm currently typing on; the screen keeps flickering. 've uploaded a video taken from my cell phone of the screen flickering. I love my white macbook but the screen keeps flickering until I keep adjusting the angle of the screen. Some days the screen flickering is minimal and I'll adjust the screen easily with minimal screen flickering. Other days i'll be adjusting for a few minutes until I can get it at an angle where the screen doesn't flicker.Here is the link of the screen flickering: [URL]I've noticed there is less/to no flickering at all the closer I adjust the screen downward, i.e., the closer it is towards the macbook itself being closed.
As for the Macbook itself, it was purchased in December 2006 and have had AppleCare since. In June of 2007 I took it in to Apple since I noticed the screen flickering very minimally only when the screensaver came on. I was then told a small soda spill was on the logic board and AppleCare would not cover it, though I was still covered regarding all cosmetic repairs, aside from that soda spill. It hasn't been till the past 2 months the screen flickers heavily and I'm just sitting at my desk adjusting the screen until there is no flickering so I can get my work started. I was considering selling my Macbook for anyone that wouldn't mind the screen flickering but i've upgraded this Macbook with a 500 GB hard drive and before attempting to sell it i'd rather fix the problem myself.
Everyone, I'm all ears. I'd love to fix this problem. If it means completely voiding my AppleCare warranty and opening up my Macbook, so be it. the warranty expires in 6 months anyway.

I did a quick search of the forums, and so I know there are previous threads about this. But my screen is flickering a lot lately and so I plan on either sending it to Apple, Driving 3 hours to Dallas since it's the closest Apple store, or taking it to an authorized repair place here in town. I just have a few questions for anyone that has either had this problem before or maybe just has dealt with repair issues before.1. Should I wipe my Hdd?2. Which of the three options would be the better bet?3. Anyone know if they would just fix it or if they would replace it?

Apologies if this has been posted before, but rather than trawling through the thousands of threads, and before hitting the Genius Bar.... thought I would run this by the experienced MBP owners first.Got my first MBP (crossed over from PC back in April), and within the last couple of weeks, noticed that the screen is flickering intermittently.
Wondered if it's a glitch stemming from the switch from Graphics card as/when needed, or if it's an indication of something more serious and warrants taking it in to the Genius Bar... (don't want to part with it for days unnecessarily).

I went on a website only to noticed the black lines & columns on the page, especially at the bottom, gives off a noticeable flicker on my 13'' MBA.
Obviously with the issues of MBA screens, I'd like to check with you if the same thing occurs on yours? I'm finding it very worrisome that my screen could be faulty.

Leave it for a 10 secs and the black lines flicker quite noticeably on mine ( I have click to flash installed & you tube 5 extensions.

Almost every time I would move my Macbook Pro (I generally use it as a desktop, so move it very rarely) my screen would come on white and not show anything for an hour or so, (except a flicker or bleed of color here and there) when the image would suddenly flicker on back to normal. Now, it just stays mostly white, with lots of lines going up and down - the bit of 'color' in the lines does seem to match where windows should be on screen, but very generally, and it doesn't update in real-time, it 'refreshes' every so often. I attached a photo so you can see what I'm talking about.
I had my logic board replaced about a year ago now because of a faulty Nvidia 8600 chip (have a Santa Rosa MBP). I'm currently using an external monitor - which last time was exactly what I did when the chip started dying out and external display worked just fine then, despite the fact that the GPU couldn't drive the internal display anymore, so that's not a clear indicator that the GPU is fine. When I first started having this problem, I brought it to the Apple Store, and they ran the test on the GPU and said it was fine... but that was months back, so I don't know?
I'm thinking (hoping) this is a display cable issue and not a GPU issue. Also, if it was the display cables at fault, how much would it cost to replace the display cables? (internal LCD -seems- to work fine, backlight, etc., I think it's the connection..) Also, as a side-note, since my internal LCD is no longer working, how can I boot into Windows XP (Boot Camp) on an external monitor? It seems not to 'plug and play' at all, unfortunately, and I obviously can't get to the display settings if I can't see anything on the LCD!

So I've got my MBP that I've had for about 4 months, the thing is. It just recently started to have screen flickering issues. I'll be sitting doing w/e as usual and all of a sudden the display goes dark, almost black, for a second, then comes back up again. I have yet to find any trend in when this is happening, but it is definitely happening on battery as well as plugged in, but it seems to be getting worse.any one have any idea what this could be, something I can fix on my own, or should I take it in?

On my home wifi the screen flickers on my MBP. It looks like the top bar flashes irratically in the middle of the screen. There are no other issues and works fine otherwise. Just annoying that I can read or see anything...I will attach a video later. Right after I turn off the WiFi it goes back to normal. And of course my warranty expired, so I'm trying to find a solution to this before I spend $350 more on fixing this $2000 machine.

I'm having a problem on my mbp screen, although it happened only once just an hour ago. The screen goes flickering magenta and white and some pixelated image. I needed to force shutdown using the power button because it seems to stalled. After restarting, it went to normal. I dunno if it has anything to do with the gfxstatus utility that I've installed the night before. I know it might be the nvidia graphic card itself but I just don't have a clue right now. My MBP is just 8 days old and my 1 to 1 exchange has expired since it covers the 1st 7 days only.
My MBP spec:
MacBook Pro 17" AG, i5 2.53 Ghz, 4gb RAM, 500gb Hitachi HD, 512mb nVidia GT330M video card, Mac OSX 10.6.3, with everything updated. Tthe attached pic is not showing the exact image since the screen was flickering etc and I'm just using a camera photo. I just noticed while I'm just surfing this forum + facebook, my temperature is at 67-70 degree celcius, which is high (normal around 38-45). I look at Activity Monitor and found that Kernel Task is using up to 80% of CPU. I have a feeling that this is not normal, and it had not happened before.

Recently I connected my macbook air (bought it in 2011, now on Version 10.9.3) with a Panasonic TV (TX-32LM70F) via Thunderbolt to HDMI adapter. After I disconnected the external device, the macbook air's screen still worked normal, but when i restarted it, it was only flickering grey.
I found out that it actually boots normally and i can use it with an external monitor (in fact I am using it right now), but that the built-in macbook screen simply doesn't work anymore.
I tried to restart while connected and while disconnected to an external screen, I have reset the SMC Controller, I have reset the PRAM Controller, but it hasn't changed.
This is actually the second time something like this happenend (it was another external device i connected it to), and last time, about a few weeks ago, it just worked again after a few days for no reason, all i did was wait until all energy was gone from the battery and the reload it. So might it be a battery problem? Or is it some controller i don't know? It was the same phenomenon two times: connect to external monitor - disconnect - built-in screen still works - restart - built in screen only flickers grey - macbook still boots and works fine with the very external monitor that might have caused the problem.

Thing is I got hold of a 1ghz 17" iMac almost for free, it had a dead logicboard (I checked it with a voltage-meter), but I figured I could fix it and have a small hobby project-thingie going on. Well I just got a new logic board today, for a 1ghz 17" iMac g4.
Things is I only get a bright grey screen from my Mac when I boot. I've tried connecting it to a external display and that works fine. Everything is there.
I then reinstalled Tiger on it, with the computer connected to my external screen. And I still have the same problem. (I have now disconnected the ext. screen and is controlling the iMac from my MBP). So at least it isn't the installation.
So what is the problem? I can via an Apple Keyboard control the brightness on the blank screen, which would indicate that it does react to input of some degree.
I've read that if the inverter is dead or anything else is dead, you would get a rolling grey screen, flicker or something like that and not a steady bright grey. One thing I'm thinking is. What if somehow this logic board was for a 15" 1ghz imac g4? Can I check this?
I read that long thread about guys buying hi-res displays for their MBPs, and they had to replace some display profile? Could I maybe fix it with a different display profile-file?
I'm really confused by all this, and would appreciate any help I can get.
Model: PowerMac6,1
CPU-Type: PowerPC G4 (3.3)
and
the gfx chip is a GeforceMX4 with 32mb.
The display is a mode 9c27, manufacturer 610, serialnumber 00000, manufacture date: B84D7200.
