Screen suddenly turns black!

I have an early 2006 Intel iMac 20 inch running 10.5.3. Once in a while when I'm working, the screen just turns black. No response. The fan is running, but no response whatsoever. I have to shut down and reboot. The last time, I saw some patches of colorful flickering and then it turned black.
For the past few months, I've also seen some segments of the screen very distorted, with strange geometric shapes with stretched text, which disappears when I select it and click again. I wonder if this is related.

Try resetting the SMC: http://support.apple.com/kb/HT1543?viewlocale=en_US
Also try resetting the PRAM: http://support.apple.com/kb/HT1379?viewlocale=en_US
After resetting the PRAM go into your System Preferences and make sure your startup disk is chosen. http://ftp.georgetek.com/George/Startup%20Disk%2010.5.png
Install iStat Pro to check your internal temperatures and make sure your fans are working ok: http://www.versiontracker.com/dyn/moreinfo/macosx/27037
Do you have Apple Care?

Mac pro mid 2010 - screen suddenly turns black

hi everybody,
since today my Mac pro (snow leopard) does the following:
Sometimes the screen suddenly turns black. Only the Cursor can be seen (sometimes not even that).
When I reboot the system everything seems fine, but after a few minutes the same problem occurs.
Unfortunately I'm not able to copy the specifications of my system because the black screen is faster than I am after a reboot.
I would be glad if anybody knew what I can do about it.
Thanks guys! Chris

Safe Mode does the equivalent of a Disk Utility (Repair Disk) while it puts up that progress bar. It never get more than about 1/3 of the way across, even when everything is great. But if your drive is un-mountable after the repair cycle, your Mac cannot start up, and it will shut down.
NOT shutting down is a good sign.
Safe Mode should continue and load a minimal set of Apple-only Drivers. It does NOT load the graphics card Driver, which is why it can be useful to learn more about your graphics card.
If you are using your Boot SSD for everything, and are not using TRIM, your SSD may be clogging up with deleted data. There are several ways to eliminate or reduce the deleted data.
One way is to run any system, 10.6.8 or later, with TRIM Enabler installed, and run one pass of Disk Utility (Repair Disk) with TRIM active. This presents one additional line of output:
"Trimming unused blocks"
and pauses for up to a minute while the unused blocks are TRIMmed.
TRIM Enabler has become much more difficult to install on 10.9.5 and later, because it conflicts with the new Kernel-extension signing feature.
Edit> If you are really running 10.6.8, you can install TRIM Enabler in your active System. It is free, but be sure to get the correct version for your system. There is an advanced-features version also available for a modest charge.

Macbook screen suddenly turns black

Hi everybody.
I have a macbook pro since 20 months now.
I turn it off very rarely but, many times, I have had the problem that, after awaking it from sleep mode, the screen suddenly turns black and I have to turn the macbook down. This problem happens approximately 1 time every two months.
Here are my macbook details and the report of the problem. I hope you can help me.
Macbook pro (10.7.5): 2,4 Ghz Intel Core i5
Memory: 8 GB 1067 MHz DDR3
Graphics: NVIDIA GeForce GT 330M 256 MB

I've just now today experienced this problem, I had purchased MacbookPro with Snow Leopard, then upgraded to Lion which was actually a disappointment. I tried to use the Apple Recover Lion and downloaded it to my external drive. Then, tried to use it -that's when the problem started I got the panic screen. This has not happened for several months since the Lion upgrade, and only happened when I tried to reinstall Lion. Now taking it back to the Mac dealer to figure out what is causing this new issue. I am writing this from my old HP laptop -which is running fine with Windows 7. Don't know if buying a Mac was a good idea. This seems to be a software issue with the downloaded recovery program, Apple should fix this asap not in 6 months, there are posts about this for a year now.

My screen suddenly turned black and wont start again

I was using my computer as usual when the screen suddenly turned off. It wont start again! I'm a musician and work with my computer!! Today I have a show and wont be able to use it!! I'm desperate Please, can anybody help!!
Thanks a lot!!!

It sounds like you had a hardware failure. You can try doing a SMC reset, read the instructions carefully though as they cover multiple models of Macs. If that doesn't help I think it's time to contact a AASP. The AASP site is for the US, you will need to find one in Brazil though.
Good luck!

IMac screen suddenly turns black

iMac screen suddenly turns black

Suddenly shuts down, after few moments can be started and used again like normal. Started occurring when mouse and key board batteries where low ? coincidence-- batteries now changed but still happened once.

My iMac screen suddenly turn black and white when I'm in fullscreen mode. What could be the cause of this problem?

Hi, once in a while the screen on my 5K imac turns black and white when I'm on youtube watching videos in fullscreen mode. It also exits the fullscreen mode automatically from one second to the next and a warning pops up saying how I can exit the fullscreen mode. Does anyone have an idea why this happens and if this is a software or hardware problem?

I'm using a Dell laptop with Windows 7. I've set the resolution to 1024x768, though the maximum resolution on this can go as high as 1366x768. So this is a problem that no one has been able to figure out? I've ran lots of other Flash-based applications that went fullscreen with no problem, so I'm wondering what other methods there are to try, if possible.

If your iPod Touch, iPhone, or iPad is Broken
Apple does not fix iDevices. Instead, they exchange yours for a refurbished or new replacement depending upon the age of your device and refurbished inventories. On rare occasions when there are no longer refurbished units for your older model, they may replace it with the next newer model.
ATTN: Beginning July 2013 Apple Stores are now equipped to do screen repairs/replacements in-house on iPhone 5 and 5C. In some cases while you wait. According to Apple this is the beginning of equipping Apple Stores with the resources needed to do most repairs for iPhones, iPads, and iPod Touches that would not require major replacements. Later in the year the services may be extended as Apple Stores become equipped and staffed with the proper repair expertise. So, if you need a screen repaired or a broken screen replaced or have your stuck Home button fixed, call your local Apple Store to see if they are now doing these in-house.
You may take your device to an Apple retailer for help or you may call Customer Service and arrange to send your device to Apple:
Apple Store Customer Service at 1-800-676-2775 or visit online Help for more information.
To contact product and tech support: Contacting Apple for support and service - this includes international calling numbers.
You will find respective repair costs in the appropriate link:
iPod Service Support and Costs
iPhone Service Support and Costs
iPad Service Support and Costs
There are third-party firms that do repairs on iDevices, and there are places where you can order parts to DIY if you feel up to the task:
1. iResq or Google for others.
2. Buy and replace screen yourself: iFixit

Is this a common problem?

That coverage is for the MacBook Pro, not a 2006 MacBook.
+Website Says:+
These are Mac Book Pros manufactured between May 2007 and September 2008.
It could be an issue I've seen with a bad backlight. Try moving the screen in small increments all the way back and all the way forward. This may trigger the screen to go blank. It's either a bad connection between with the display or the LCD has gone bad.
Your MacBook is out of warranty so there might be a cost if you go to an Apple Store to get it fixed. http://www.apple.com/retail/geniusbar to visit a store (if you are in the US. If not I can give you additional information)

MacBook Pro screen randomly turns black on me for no reason while I'm using it? What's wrong with my MacBook?

I have a MacBook Pro from 2009 and the screen randomly turns black on me for no reason while I'm using it? It takes anywhere from 5 seconds to 1 minute to turn back on and no matter what I do it just has to fix itself so idk if it is going in to sleep mode or what. Anyone know the issue? Thanks.

Run through them and stop after #16 or if the problem stops, or if something tells you something severe (like hardware test giving a error)
If you can backup your personal data off the machine, you should do that first.
Hardware issues we cant' fix, only a few things may fix it.
Software issues we can fix, but right now we don't know what is causing your issue as we can't see it obviously.
So your going through a process of elimination to try to give us a clue what's the problem and then we can advise a course of action.
If you feel this is way over your head, then just make a appointement with Apple and/or your local PC/Mac specialist.
We are only other uesrs here, helping other users.

My screen has turned black as if the LCD screen isn't working. There is no damage and the phone is still responding to vibrations and there is a dial tone when called. What is wrong with my phone?

My screen has turned black as if the LCD screen isn't working. I have tried using the lockbutton and home button to turn it on, but it doesn't work. What should I do?

Your phone is probably broken.

MacBook Pro Screen suddenly turns blue

I have a MacBook Pro that I've had for about two years now. Lately, I will be surfing the net (generally use Firefox), and my screen suddenly turns blue. If I close the lid, reopen, and push the power button, it fires back up. Anyone have any ideas what might be causing this problem?

I have exactly the same problem 3 month ago and until now it still happen. I took my macbook pro into apple store two time. first time, they check that diagnosis of the hardward generated and it turn out clear. nothing happen to it. then they check my software and find that there is something wrong with safari. so they decided to reinstall everything.
And they told me to not install everything back from your time machine just install the folder that I want. And try that for 2 weeks. Since that it been working fine until last week, macbook suddenly turn blue again but this time it shown random colour with line and shape before it turn to blue screen.
Now i dont know what to do as mine warranty just expired 3 days before it happen. I think it gonna cost a lot without warranty.

My iphone screen doesnt turn black when im on the phone

my iphone 4 screen doesnt turn black when im on the phone and its not the case and i havent dropped it, is there anything i can do without having to get a new phone. i would get a new phone if i need to but i would like to fix it without having to.

The Ambient Light Sensor may be malfunctioning. Unfortunately there is not much you can do without tampering with the phone internally and voiding the warranty. Your best bet is to bring the phone to a local Apple Store and have them inspect it.
