Macbook pro screen blacks out

I just bought my first Mac. I have noticed since I received it a couple weeks ago, that the screen blacks out occasionally. I am pretty sure this mostly happens when I am in Safari. Any ideas why? This will happen with my ipad 1 every once in a while too. It will black out and revery back to the home screen.

You should take it into the store as it certainly could be a hardware problem. In my case, however, i didn't notice it when I was on Lion, noticed it on ML, and then haven't seen this problem again since downgrading to Lion.
Since your problem is intermittent, it might be hard to produce at the store. So, you might want to try to capture it on video before you go to the store so you have something you can show them.

Macbook Pro Retina blacks out for a few seconds at a time

I have a new (2-3 weeks) Macbook Pro 13" retina display. A few times since I've had it, the screen went black for about 10 seconds and then came back. Any idea what's up with this? Is this something to return the machine for, or is a software issue? Has anyone else had this happen?
Thanks!

Macbook Pro screen blacks out keys stay lit

The gist of it is in the subject
Pretty much without warning, does not have a preference for type of application being ran, the screen will completely black out. If sound is being play it either stops or begins to skip. The keys stay lit. The only way to bring it back is a hard restart.

Ver 10.0.1. Entire screen blacks out for a few seconds when scrolling.

I recently updated to Reader X 10.0.1. Now when I scroll through a large document my entire screen blacks out for a few seconds. So far it has recovered. I get an error message saying that the NVidia nView driver (ver. 135.50) has stopped responding. I am running Windows 7 Pro on an HP Laptop, feeding to a large Samsung monitor. Never happened prior to this update. Any fixes/ideas?

Screen blacks out for a few seconds occassionally

Sometimes my screen blacks out for a few seconds, then comes back on again. I have an original Titanium powerbook. Is this a warning signal of worse to come? I know I should replace the computer soon, but it's working just fine for now. I just don't want it to die before I've moved on to a new machine.

Hi Julie,
Obviously no one can predict with certainty what the future will bring, but if I were in your shoes, I would certainly think there was worse to come.
Many things could be causing this, but it sounds like a short circuit or bad connection, possibly with the display cables running through the hinges, or where they connect to the logic board. It could also be a sign of the display dying, though they usually just get dimmer and dimmer or simply die.
Does the "blinking" correspond to any movement of the PB?

Hp pavilion 15 screen turn off for few second when i turn on or off charger

Hello,
I bought new hp pavilion 15. i notice many time when i turn on or off my charger, screen turn off for few second then after few second screen turn on. please help me out its furstating me .
This question was solved.
View Solution.

>> It is customary and in this case Necessary for you to provide the exact model of Notebook you have a problem-with. [ There are MANY variations of HP Pavilion 15-T Models, for example. ]
>> You should always be sure you have installed/applied ALL updates for all of your Notebook's hardware devices, and ALL Windows Updates labeled "Important" and ALL "Optional"-section Windows Updates for any hardware device in your Notebook which the Windows Updates service detects (and offers an Update for).
>> For example, this link: http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?os=4158&lc=en&cc=us&dlc=en&sw_lang=&product=6787... has the latest HP Drivers and Patches for a specific variant of the Pavilion 15-T.
>> AFTER you are certain you have all the latest drivers and patches in-place, you can try the 'old Trick' as follows: Shutdown Windows; when your Notebook has turned-Off completely (after Shutdown completes), THEN remove the AC Adapter connector and remove the BatteryPack.
>> Hold DOWN the power-button continuously for a full 62 seconds. Then put your BatteryPack back in your Notebook. Do NOT connect your AC Adapter yet. Power-On the Notebook and Logon into Windows. Check the Control Panel\Power Options settings and find out the Charge Level of your BatteryPack. If it is below 25%, then (and only then) plug in your AC Adapter and connect it to your Notebook... and let the BatteryPack charge up "completely" to 98-100% Level. *Note: if your Adapter has a removable AC cord-connector, be certain that connection is 'tight'. <Do NOT stick your fingers or ANY object into any AC Adapter!> If you even think your AC Adapter is faulty, GET A NEW ONE! Damaging a $400-$800 Notebook PC is NOT worth it, versus the cost of a New Adapter.
>> Use the built-in Help functions of your Notebook to find out how to DISABLE(!) "Hibernation", and eliminate that TROUBLE-CAUSING 'feature' of Windows PCs. When you have done so, always REStart Windows, to be certain the changes are applied. *Many changes and Updates take place 'Fully' only "during" Shutdown and/or "during" Startup of Windows PCs. [While Windows O.S. is "running", most of it's System Files are LOCKED.]
>> FYI: always let your BatteryPack run down to it's Lower setting BEFORE you plug-in your AC Adapter/Charger. Charging any rechargeable BatteryPack at "mid-charge-levels" causes shorter BatteryPack life...

Can hear audio, but video blacks out every few seconds; picture comes back when we hit the tv's volume button

We can hear audio, but video blacks out every few seconds; picture comes back when we hit the tv's volume button. Everything seems to be plugged in well. The picture even starts out being sort of dim. And it goes through phases of working fine but then will randomly start blacking out again. Any ideas?

Welcome to the Apple Community.
Have you tried turning the TV off and on again.

We regularly use Cocktail by Maintain software. You run the whole gamut of options but the important one is in System - Databases - Rebuild launch services. Also in Files - Caches - then clear the lot.
This is just houskeeping really but there are so many 'links' in A/cad it needs 'cleaning'

Standard def STB repeatedly blacks out for a second or 2

A site search on "black out" does not turn up a similar issue, of course it may be my search skills are lacking.
New subsciber since Sep 2010. I have 3 boxes, 2 standard QIP2500 phase 3 (basement/MBR) and 1 hi-def (LR). Hi def TV in MBR, standard in other 2. Both standards would on occassion 'black out' for just a second or 2 ever since original install. No problem with the hi-def. One standard is wired with coax, one with s-video, the hi-def with HDMI. When the black out occurs, the screen will freeze for an instant, then the screen goes black, then it comes back. The information on the box does not black out, the TVs don't power-off and restart. It's just the screen goes blank and then comes back. It happens without any seeming warning, and will happen at any time of day. Sometimes it will happen repeatedly, sometimes it won't happen for a long time. Both boxes have been repeatedly reset and rebooted with no improvement. During one tech call the tech had me relocate one of the standard boxes to the hi-def location to isolate that it wasn't a location (in-house cable) problem. I thought it curious since it was happening at 2 different locations but went through the drill anyway. The relocated standard worked for a few minutes, then went black for a second as the problem does. Plugging the high-def back in resolved the issue at that location. The tech said he would send 2 new standard boxes. The replacement boxes have not resolved the issue. Any suggestions?

if it's doing that on two different boxes using both coax and s-video then I think that leaves a possibility of the coax. that would be a unusual symptom of a bad coax/splitter but try this.
Wait for it to start acting up - when it starts acting up, stay tuned to that station, and hit your menu > customer support > in home agent > network diagnostics and click ok to start.
check the video signal using that menu selection. after it's done running it will give you a general message like "you're video signals are not in the optimal range" after you see that, hit info and then look at the SNR DB it should give you a number.
32-36 is optimal, below that is questionable.
If it is below that then it's probably going to be a problem with the splitter at your house, and you would either replace it yourself, or call verizon to replace it. be sure to tell them the DB

Black vertical bar with lines on Macbook pro screen Appeared out of nowhere

I was working on my computer late at night. Like always.
I went to bed, and left the computer on in it's screen saver , as I always do.
When I woke up I had a black vertical bar on the screen about 1 1/2 inch thick with some flickering lines next to it.
here is what it looks like: http://www.talkcitee.com/ourspaceimages//2coolcode/2coolcode.jpg
I don't believe this to be a memory problem, I can take snapshots of the full screen, and I can hook up an external monitor with no problem. Also restarded PRAM plenty of times, etc.
But this black bar appeared out of nowhere. As if one way my screen decided it was going to blow out on me out of nowhere. I've had this MacBook for 2 years.
Question is, do you think the problem is:
a) the screen
b) connection / short problem to the screen inside the macbook
I hope it's B , because they told me it would cost $800 to replace the screen which is stupid cus I can get a new macbook pro for less than that.
I think there is a connectivity problem with the hardware , possibly a short, or something messed up with the wires or pins that link to the screen.
I noticed after repeatedly opening and closing the macbook, there were some changes in the small flickering lines next the big bar, and some of them turned solid black.
Has this happened to anybody else before?
Message was edited by: Uhuru83

Usually what happens is that over time the cable comes loose from the back. This happens because the enclosure within the hinge housing is quite tight and the LVDS cable has little room to move around. Because of the frequent opening and closing on the lid, the cable starts to move out of place try opening and closing it a few times and push it back very gently. You might see the line disappear or decrease slightly.

Macbook Pro screen blacks/colours out when laptop is moved

Hi all,
I have a 2010 Macbook Pro 13" running OSX 10.8.2.
In the last 24hrs or so it has begun acting very strangely. The screen has been blacking out when the computer is lifted off a surface or tilted backward to sit on it's spine. At first, it was just when it was moved to put pressure on the back left hand corner, but now it will black out when it is nudged and even with no movement at all. Additionally, the screen now not only 'blacks out' (mind you, it still appears to be backlit), but it will also black out to a specific colour. So far, my screen has been completely filled with bright pink, and then green, on two separate startups. I have had to do a forced shutdown when this happens as it becomes completely unresponsive. If I try and reboot too soon after forcing shutdown, I get intermittent beeps that are synchronised with the light on the front right hand side. When this happens, I get no Apple chime, no response from the keyboard, nothing. Have to force shutdown again and wait for a while. The beeps seem to be one to every five seconds.
My first thought was RAM or the display cable, but after replacing the custom RAM with the original RAM I got with this computer, the only difference I found was that the beeping at startup stopped with one of the custom chips out. The screen issues persist.
Moving the display angle of the Macbook Pro does nothing to return the display. Keyboard stops functioning. I've tried booting into Recovery, but often this hasn't worked. I've reset PRAM and SMC but have not noticed any difference.
Any ideas would be much appreciated

It sounds like a defective Mac. I would see what the Genius Bar says.

Mid 2010 MacBook Pro 15" Blacks Out Without Warning

Quick Summary of Problem: My MacBook Pro is currently shutting down without warning. It would be more accurate to say that the screen goes blank but the machine remains on as can be heard by the fan. Nothing resolves it without powering down and restarting. It has occurred when attached to a power source or via the battery.
My machine specs: Mid 2010 MacBook Pro 15” with 500GB hard drive, 8GB RAM, Intel HD Graphics/nVidia GeForce GT 330M with 512MB, anti-glare 15” screen with max resolution 1680 x 1050). Running Snow Leopard 10.6.8 with 2013-001 Security Patch installed.
I have AppleCare which commenced when I first bought the machine in July 2010.
System Profiler says my battery condition is ‘Normal’. Cycle count: 610.
Detailed Summary of Problem: Back in January, my MacBook Pro shut down several times without warning. Each time, I was creating selections on high resolution imagery in Adobe Photoshop CS5.
Not long after, I saw the ‘MacBook Pro SMC Firmware Update 1.7’ relased on Feb 12 (http://support.apple.com/kb/DL1633) and installed it via Software Update. By coincidence or not, my MBP behaved much better afterwards and the seemingly random blank screens requiring a restart disappeared.
But then I installed the ‘Security Update 2013-001 (Snow Leopard)’(http://support.apple.com/kb/DL1642) via Software Update and that’s the only thing I can really remember changing to my system. Since then, the black-outs have reappeared. As before, I was usually using Photoshop and working with high resolution imagery. However, one time the machine blacked-out, I was simply doing a two-finger scroll on the built-in trackpad whilst in Chrome (Version 25.0.1364.172).
The blackout has occurred twice now not being connected to power, and twice with it being connected to a wall socket. Needless to say, I lost work in Photoshop (even though I’ve begun to save more regularly) and now it feels like it’s a ticking time bomb and I don’t know when it’s going to go off.
One thing I’ve found rather odd is that in the crash log, the kernal version doesn’t seem right for Snow Leopard:
Kernel version:
Darwin Kernel Version 10.8.0: Tue Jun 7 16:33:36 PDT 2011; root:xnu-1504.15.3~1/RELEASE_I386
System model name: MacBookPro6,2 (Mac-F22586C8)
The full crash log can be found at the bottom of this post.
Fixes I’ve tried:
1) Resetting the NV-RAM has done nothing. (was suggested
2) I’ve tried reinstalling the ‘MacBook Pro SMC Firmware Update 1.7’ by downloading the manual installer from Apple, however it now says ‘Alert: This software is not supported on your system’ which in a way makes sense given I’d already applied the firmware update, but a more accurate message along the lines of ‘This firmware update has already been installed’ would be more reassuring.
3) If all else fails, I could resort to copying over a backup I created with Carbon Copy Cloner, which was done before I reinstalled the 2013-001 Security Update for Snow Leopard. But that’s a bit of a headache too, because my documents I’ve updated since the backup will be out of sync. Another reason this isn’t a great solution is that I can’t take advantage of the 2013-001 security update, nor future ones.
Any suggestions? There’s probably no good time for something like this to happen, but this is a particularly bad time – I’m currently beginning design and finished art freelancing and brushing up on some applications I haven’t used in years. Nor am I going to make an impression meeting with recruiters without my folio being presented from my MBP.
I’ve already booked a Genius appointment 2.5 days from now, but all help and ideas greatly appreciated!

I am sorry. The page that came up has an AD for issues with a 13" MacBook Pro in the corner. I read the AD as if it were part of the article and assumed the whole page referred to the 13" model. My Mistake.
However, the issue described by TS4088 is not a soldering problem. It is a Latent Defect -- a flaw built into certain batches of those chips from the day they were packaged and installed.
If your Mac fails the VST test used to detect this Latent Defect, re-flowing the solder is likely to have NO EFFECT on its performance -- the solution is the remove the defective chip and replace with a good one.
There certainly can be problems in these and other Macs where a re-flow would be beneficial. But I caution Readers not to generalize your solution to Macs that are known to fail VST. Re-flow alone will not solve the Latent Defect problem.

Macbook pro screen blacks out for few seconds?
