MacBook Pro :: Screen Flicker All Of Sudden System Stuck
Feb 3, 2010
I don't know if it depends by a latest update I did to Itunes but after an uncertain amount of time my MacBook Pro 2.2Ghz Santa Rosa start to flicker. I have posted a video in youtube [URL] so you can see what happend. For a small amount of time while flickering is started the mouse can move around then it stuck and lock me out of the system. I have to reset many time PVRAM and SMC then it will restart until it lock it down again. It worked flawlessly until yesterday after if I don't remember wrong one or more software update. I use Snow Leopard (official licence). I downloaded the Combo Update for Snow Leopard and ran it. I still have to test it again. Since I need to do some work in the next 48 hours I can't full test it. After the hard reset an image pop out and It won't let me start up the system again ever if I reset many times PVRAM and SMC Then I use bootcamp to "unlock" the MBP. I do run windows under BootCamp. It will run but I can't see anything since the video remain black (I hear the HDD until stop working) Then I push the power down button and I turn off the windows Then after a long time it will log into Snow Leopard! I'm getting crazy the last two days
I tried fsck -f fsck -y multiple times, booting in safe mode, zaping the pram and all that stuff, nothing as worked. I don't really care about how to fix it but I care more about, Is there any possible way I can get files off of the macbook even though it wont boot. Like is there a way for another computer (windows or mac) to pick it up so I can transfer files? What accessories will I need?
I recently upgraded to a Macbook Pro 15" with a mini displayport, and I decided I would share my LCD monitor with my windows box. The desktop box is connected with DVI and I have connected my Macbook through an HDMI adaptor from Moshi. Everything works very well, and I'm pleased with the quality of the output, but I'm having trouble with a screen flicker in full screen games.
When I select full 1080p (1900x1080) in any full screen game, the screen "shudders." It does not occur on the OS X desktop, and I can only explain it as a shudder. Lines and text shift perceptively left and right, and the game is unplayable. I have experienced this problem in Starcraft 2, World of Warcraft, and Half Life: Episode 2 so far.
Could the problem be with my monitor and the way it handles an HDMI signal? The Macbook is flawless otherwise, with no other issues of any kind. The "shudder" only occurs during full screen games set to 1900x1080. Lower resolutions are not effected and work fine...
I'm stumped.
Edit: I should add that I have no other 1080p capable devices to test the output with.
I am trying to install windows 7 on macbook air, through an external DVD drive, since USB didnt work for me. The DVD is detected and ounce I click start windows installation, the system boots and gets stuck at the gray boot screen with the apple logo. What is causing this? how can I solve this?
I bought a new HDMI adaptor for my 17" Macbook Pro. I'm plugging into a full HD compatible TV, into an HDMI port.The result is a consistant switch between the actual correct display, and colored static. The rate of the switch is dependent on the frequency of the refresh rate, but there's no way to get it anywhere near comfortable to use. I have tried changing resolutions on both sides to no avail. Here is a video of the screen periodically flickering between display and static url...Also have tried other HDMI ports and cables, all of which are known to be in working condition. Tried restarting the tv and computer. Running out of ideas and hair.Troubled Mac User
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..
So I got a new Late 08 MBP 2.8 earlier this week. Everything has been great except that occasionally (once or twice an hour) my laptop screen will go black for about 200-300ms and then come back. Often only the top 1/2 or top 3/4 of the screen will go black. I was worried it was the LCD, but today I switched over to the 9600gt for the first time and the problem seems to have gone away. I generally code all day and havent been doing anything intense when the flickers happen, the CPU/GPU temps are also low.
I have an external monitor hooked up. Ive only noticed the problem when the external monitor was hooked up but then again 90% of the time I use the computer it has the external plugged in.
Also does anyone know if the 9400m's 256mb of memory is shared with the main RAM, ie if I am running on the 9400 do I only have access to about 3.74 gigs of ram?
I have a 13" MBP 2.53GHz, and I absolutely love it. However, I have one issue. I am using an Apple display port to DVI adapter to run the MBP in clamshell mode with my Samsung 221BW monitor. On websites or programs with a dark grey background, the screen flickers. The resolution is set to 1680x1050 (native) and 60Hz.
Does anybody else have this problem? Any ideas as to fixing it?
Every time I moved my MacBook Lid my screen turns off and starts to flicker? Is there anyway you think i will get covered I haven't got any warranty left in it either.
My over 3 year old MacBook Pro Unibody (Late 2008) have a giant problem. The 9600m GT GPU is not working anymore, when booting up with that card the screen flickers and the OS crashes. I have been apple to boot it up with the 9400m GPU, where it works somewhat, no screenflicker, but it does crash alarmingly much as well as giving me a lot of kernel panics. (sometimes it can't boot the OS before freezing, and other times it crash while trying to shutdown the OS).Â
Since it is over 3 years old, there is no more gaurentee, so my question is:Â

This is my first post on Macrumors and unfortunately it is in regards to a problem that I am currently experiencing with my brand new Macbook Pro 15" w/anti-glare upgrade. I purchased the unit on the 28th May and have used it without problems for until yesterday when I noticed some intermittent flickering in the screen generally a horizontal banding that happens quite sporadically and also changes in brightness levels etc. I checked in with an Apple store earlier today and a staff member at the Genius bar couldn't figure it out either. She tried installing new firmware, but the problem remained and told me that she suspects it is an issue related to the firmware as opposed to hardware. The only advice was to wait it out until Apple addresses the issue with a new firmware upgrade?
I can honestly say I'm not very impressed since this MBP was my supposed long-awaited transition from a lifetime user of PCs to the supposedly more stable/reliable Macs! Just my luck I guess. Nonetheless not a great start to my Mac experience. Anyways, just wanted to see what is the best way to go about it and whether I have the right to demand for an outright replacement (I will be heading off overseas on the 24th June and will definitely need it while away), which may be an issue in itself as I don't think any retailers (I'm located in Sydney) have the 15" w/anti-glare model on hand/stock - mine took over 2 weeks to arrive via a special order. Peoples thoughts? Anyone else experiencing similar issues? Only thing that I could find of relevance were the problems experienced earlier this year with the 27" iMacs.
have an ibook G4 and i was updating my leopard system. after i installed the package the update said something about receiving cache but i waited there for 1 hour and the screen just had a background doing nothing. i grew impatient and turned the comp off. now it wont log in! theres just the grey screen with the apple and it wont go any further(this cpu was bought second handed so theres no discs it came with)
I am using the pair with an early 2008 Mac Pro octo 2.8. Previous card was a 8800 GT, and previous monitor was a dell 2405WFP. No issue there (other than the 8800's fan noise).With the new setup, I occasionally get a whole screen flicker for a split second, and just now when I woke the display from sleep I got multicolored snow covering the entire screen, like this:

Has anyone seen this with either the EVGA card pushing some other dual-link 30" display, or the 3007wfp-hc driven by some other card? I don't really have an easy way to test this myself, as it is pretty intermittent the two arrived around the same time, so I'm not sure which is the cause, but I haven't seen any problems like that in XP so I'm leaning towards the card (drivers, perhaps). I don't spend much time in XP, though, so I'm still not sure.
I bought this machine after selling my old Aluminium MacBook expecting simply better battery and a bit faster, but there's tons of little updates that I'm thoroughly impressed with.
- Unplugging a cord or device from MBP doesn't flicker the screen when in sleep
- Screen "fades" in after sleep instead of instantly popping in
- If I have the screen at lowest brightness, and wake from sleep, before it would flicker full brightness then go to low again, now it stays low
- Backlighting had so much bleed on old MacBook that it was painful to use, it "bled" everywhere. Now it's only the letter of the key and a small rim around the key
My family owns two MacBooks and an iMac. All of these computers share the same internet (a wireless Bell EWire modem (which probably doesn't tell you much...)). My MacBook and my father's iMac connect easily and have connected to the internet for as long as we have had these computers (a few years). The other MacBook has connected up until a few weeks ago (it is a year younger than my MacBook). A few weeks ago, when the MacBook was closed (put to sleep but not shut down) and reopened, the airport symbol would display a working airport and connection but when I clicked Safari, it would not connect.
I've had my MBP since Oct of 2007. About 2 weeks ago it would not turn on so I had the logic board replaced. After I got it back it would randomly shut down, the only solution I could do is take out the battery and work at the lower clockspeed but it still shut down without warning, just less frequently. I thought it might be the power cord or the battery so I got those replaced but it is still happening. The first day I had the battery (yesterday) it worked fine, no random shutdowns, I calibrated the battery per apple instructions and today it worked great (during charge up and plugged in at full charge) for about 5 hours, then it shut down, I turned it back on and it shut down shortly after, I reset the SMC by taking out the battery and holding down the power button and putting it back in and it shut down again.
Then I tried to run the hardware test and it shut down again so now I am posting this out of frustration. I also reset the pram and it shut down again. Now it won't stay on for more than getting through the login screen. I don't have applecare but they replaced the logic board for no cost (which I don't fully understand), I'd rather not take it back but I will if you guys have no ideas. I looked up (with difficulty) the previous shutdown code: -2 (http://www.macwizard.com/errors.html) and it said it was a "General System Error (VBL Mgr, Queue) -2 vTypErr invalid queue element" but I have no idea what that means.
For some reason I don't have the screen at top of screen where I type www. whatever screen or the arrows to go back one screen. It use to be there all the time. I don't know what I did.Â
My Mac screen is weird. Yesterday my Mac was making beeping nosies <--fixed. But today when I turn on my Mac the screen is divided by two... And it also has like weird lines all over the screen. I put in my pass word and the screen all of sudden just the screen is divided by two
In the last 5 days I've started noticing a strange flickering with images loading in Safari both static and in-line video e.g. cnn.com. A few days ago at lunch while home I opened both Safari and Firefox, opened cnn.com and then clicked on a video. With both videos playing at the same time it looked fine in Firefox but flickered in Safari. I've noticed the same issue with static image loads too. In FF the image loads no problem, in Safari it flickers. I don't think this is related to the video card (8800GT) but sounds like a software issue to me.
Anyone else having a similar problem? BTW, I'm running 10.5.2 with all the latest updates. I've subsequently noticed that turning the machine off and on again relieves the problem?
My monitor has been flickering in all my graphic programs. I'm thinking this has something to do with OSX 10.5.8 and the ATI Radeon 9000 card in my G4 MDD. I've swapped out the ATI card for another of the same quality to see if I get the same problem. The flickering came back. I am now trying out a generic lcd (cornea) to see if the problem occurs.
I have had my imac 21 for about 5 years Model identifier say 7.1. running OS 10.6.8 Has been going well apart from a new hard drive. Suddnely tonight the screen flickers when you first turn it on for a few minutes and then settles down but dims down where whites become a light grey. Tried turning off the monitor screen power off and power saver.
I have been experiencing a problem lately. Once a while my MBP '10 screen will have a sudden drop of brightness and then back to normal. Does anyone have similar problem?
My Macbook Pro display all of a sudden went to the 'white screen of death' as I've heard others refer to it as. I've tried zapping PRAM, resetting SMC etc. to no avail. When I connect an external monitor, I am able to use the Macbook without problem, so I know it is video card/controller/display related issue. I'm going to send the Mac in for repairs. But before doing so, I'd like to erase my hard drive so I'm not sending them all of my data with the computer. I've done a time machine backup, so all is fine there as well.Â
My problem, is that in order to erase the hard drive, I need to boot from the OSX install disk. No matter what I try, I can't do this with my external display. If I insert the disk, and hold down the C, my Mac never recognizes the external display plugged in and so I cannot see to get to the disk utility tools on my OSX install disk. I've tried using Command-display dim button, to no avail.Â
I've tried simulating a clamshell mode boot where I close the lid as soon as the boot starts (with the OSX install disk in the drive) and I get a kernel panic every time. Even if I didn't, I don't see how I can close the lid at startup and hold down the C key at the same time. Â
Handbreaked some stuff to be played with my appleTV. The files are 600mb-1Gb files (720x480?) with one pass deinterlace. The problem is that when I am playing them with my macpro, I get a white flicker when trying to play them full screen. Like a white strobo. When resizing the window smaller, they develope a black flicker. Only when doing playback in a smaller window (1/4 of the screensize) they play back normally. Display is a 30",so is my 7300Gs such a useless p.o.s or what is going on?
i bought a used 24" aluminum imac (2008 model) that was about 6 months old, but recently the screen has began to flicker...usually from a half to a full second every few hours or so. it sometimes will flicker if the mac is nudged on either side, but this doesnt always happen, even when i TRY to initiate it. its not really major, but im just worried that the whole display will crap out soon. ive found threads about screen flickering with macbooks and led displays, but nothing for imacs yet. im not sure if this matters, but the person i bought it from opened it up and replaced the hard drive. another contributing factor may be that i constantly run torrents and my mac sometimes stays on for days at a time. it doesnt seem to overheat and ive never had this problem with my other imac (2007 17" white). when im not using it, i keep the disks active, but put the monitor to sleep to prevent burn in. im assuming that since this guy replaced the HD, this would void any warranty, so i think im pretty screwed as far as thats concerned unless i pay out of my own pocket.
Recently i've started to experience my iMac screen flickering for approx 2 seconds, and then turning back on. I was wandering if this was a common problem with this model of iMac (purchased mid-09, 2.66ghz 4gb ram model). I had read of such a problem with the new 27", and in some cases even with the 21.5".
I have only recently begun to use the iMac for relatively graphically-intense tasks, and was wandering if perhaps it could be a dying graphics card (or perhaps it was always faulty, but the lack of intensity of any programs run never pulled it up originally?), or if maybe it was an issue with the LCD?
