Another black screen thread

Ive had my imac since its release in 2009, its the 3.06 ghz pre I series processors, never had a problem, had a clean system and it was always perfect, and the HDD and RAM were at the best standards (speed and large capacity- working for 2 years). So the problem is that all of a sudden my screen goes black, rebooting didnt help, i bought a monitor adapter and after a couple hours the computer worked until i tried to connect to the internet, my wifi would work (ps4 and iphone) but on my imac the wifi signal icon was empty, so then i turned it off and now its black again and nothing works.
What could this be?
How much will the repair be?
Why is this happening so often lately?

Sorry friends. I forgot to put a copy of my current bios. It's located at:
http://s000.tinyupload.com/?file_id=76092744978041263239
Please let me know if this is most current one and send me an update. Thank you so much.

Another Black Screen on Capture issue!

Hi, Note with interest I am not the only one to be confronted with this issue. I have a Sony HDR HC7 HD (HDV) camera and on intial set up of my installation - used this camera and through Easy Set up chose the Apple codec 1080i50 for PAL video capture and every thing was hunky dorey.. Indeed great stuff.. Subsequently I needed to video edit some SD video taken by another Sony camera DCR PC330 PAL and reset the Easy set up to accept SD video. It worked -and is still working. The problem I now have is try as I might - by going back to Easy Set up and reconfiguring to the original settings for the HD camera I am confronted by a black screen on capture. Everything else seems to be fine.. the camera whirrs and starts up but there ain't no flaming picture!! Help!

I found that at https://help.ubuntu.com/community/UEFI
Set up the BIOS in EFI or Legacy mode
Some recent computers (>2011) allow to set up the boot either in UEFI mode or in Legacy (not-EFI) mode. The way to carry out this setting depends on the computers, but generally this setting is located in the "Boot order" tab of the BIOS (to access the BIOS screens, it is generally necessary to press a key during the PC startup).
Note: Some BIOSes (e.g. American Megatrends' "Aptio", found on the Asus vivobook series) call Legacy mode "Compatibility Support Module" or simply "CSM".
So if that applies to your machine, you might be able to boot Windows7 with UEFI mode and Arch+Nvidia with Legacy BIOS mode, without changing anything to the installation (the BIOS boot loader seems to be compatible wih GPT partition table, but there is to configure something for it to work see https://wiki.archlinux.org/index.php/GPT#BIOS_systems).
If you can't do that and you really do not want to use the nouveau driver, you have no other choice than to wait for Nvidia to release an UEFI compatible driver, and not to work in tty console mode.
You can also try to search how some has succeeded to use the efifb frame buffer with the nvidia driver, with special configurations.
But, apart from the BIOS switch between boot loaders, the two easiest approaches for you are either to use the nouveau driver or to not work in tty console mode when using the nvidia driver.
Maybe you could find something better but it will be more complicated, I don't know if you have time and motivation to go this way...
Nvidia will surely release a UEFI compatible driver sooner or later...
Regards.

And yet another black screen issue

As many others in this forum I suffer from the black screen problem when installing Windows 7 32 bit on my newly bought iMac OS 10.6.4. Will Apple please take care of this problem!

Apple has, in their tech notes, which can usually be found from Boot Camp Support page. I guess Boot Camp Assistant Help menu too.

Yet another black screen on TTY with nvidia drivers

Hi everyone,
I've just changed my hardware and immediately installed a fresh Arch on it. Everything was fine until I installed the nvidia drivers: from that moment, once the boot is complete I get a normal (and working) GDM login screen, but I cannot switch to TTY with Ctrl+Alt+Fn. If I do, the screen goes black, but even worse, the monitor goes into sleep mode and I cannot get back to X (with Ctrl+Alt+F1).
The machine is still working correctly though, as I can get access to it via SSH. The only problem is that I cannot use the virtual consoles unless I want to lose all X display until the next reboot (restarting it via systemctl restart gdm doesn't work).
I also tried lightdm as a replacement but it's still the same.
However, when using the nouveau driver, everything works as expected and I can switch from one TTY to another as much as I want. Of course, I'd like to keep the nvidia driver for various reasons.
I found a lot of similar issues on the web and on this forum but none had this "additional little annoying thing" which is the sleep mode that can't be reverted but with a reboot.
Any help will be appreciated. Thanks in advance.
My specs:
- MSI GeForce GTX760
- Intel i7-4771
- Gigabyte Z87-D3HP
- Boot UEFI

Another Black Screen problem ��

Hi guys,
I got an iPhone 4 like 2 months ago, which was working fine until a few days ago. What happened is, I texted to a friend with WhatsApp then left iPhone for a couple of minutes and the screen never came back. At first I think the handset wasn't working cause i was not reachable when i called myself, then I restarted it, without seeing anything just used my imagination :) but I am not really sure about it, I might also have a coverage problem.
Now I can see the icons barely with the right light angle, handset is fully operational as I understand. I can make and receive calls. I have reinstalled the iOS in iTunes, which was another headache, but I'd didn't help. Another interesting thing is it just doesn't hard reset itself. I have tried to do it several times, pushed the buttons until I see the apple logo but it just started with everything in place.
I also tried to increase and decrease the backlight thing in the settings, of course it didn't help.
Now I am going to Spill the beans out: I dropped the iPhone like a week before all this happened. But it worked completely fine until a few days ago!!!
Since there is no Apple Store in my country and I don't have AppleCare :( what do you suggest me to do?
Thank you very much in advance

If it goes out a fourth time, I would recommend calling and asking for Customer Relations and ask them to replace the iBook instead of doing another repair. It has been known to happen.
Meanwhile, you can minimize the chance of the logic board failing again by never picking it up by the left front corner alone. If you are picking it up with your left hand only (as I often do), be sure to pick it up in the center, under the track pad. The case flexing on the left side from picking it up by the left front corner can cause the graphics chip to come unsoldered from the logic board. This is what causes the familiar logic board failure.
Good luck. Let's hope you don't have any more trouble with it.

Black screen after they replaced my logic board twice

I have been getting black screens on my mac book about a month or so after i bought it i take it in all the time they say we ran tests nothing is wrong with it then i get it home and i get another black screen finally after a couple months the first time they replaced my logic board / graphics card. It continued to happen so i took it back in they ran tests said they could find nothing wrong i showed them a video of my macbook pro black screening they said they would check the memory they did and said it was loose so they replaced my logic board AGAIN now on the second day of getting my macbook pro back it has black screened AGAIN this was in windows boot camp but when it happens on that side it always happens on the mac side can anyone give me any advice / suggestions on what to do about this please?
Below is the last kernal panic before they replaced my logic board for the second time

I have been getting black screens on my mac book about a month or so after i bought it i take it in all the time they say we ran tests nothing is wrong with it then i get it home and i get another black screen finally after a couple months the first time they replaced my logic board / graphics card. It continued to happen so i took it back in they ran tests said they could find nothing wrong i showed them a video of my macbook pro black screening they said they would check the memory they did and said it was loose so they replaced my logic board AGAIN now on the second day of getting my macbook pro back it has black screened AGAIN this was in windows boot camp but when it happens on that side it always happens on the mac side can anyone give me any advice / suggestions on what to do about this please?
Below is the last kernal panic before they replaced my logic board for the second time

T60 exhibiting 1 long and 2 short beep and black screen

Hello all,
i own a thinkpad t60 with ATI radeon x1300 graphics card. I read through your complete "T61p exhibiting 1 long and 2 short beep and black screen" thread and I have the same beep problem with my t60. Let me briefly explain you how the beeps occur in my system:
My t60 had this problem after I initally formatted my system and this 1 long and 2 short beeps used started occuring. But the strangest fact is that after those beeps and blank screen, the power light in the indicator light group is on along with battery and ac power lights. But then when I repeatedly switched on and off the system, the sequence of beeps dont occur all the time. Then I completely switched off the system and when I booted the next times I started pressing the ESC keys after pressing the on button. Most of the times ( 8 out of 10 times), the first 4 times it produced the same beep codes but after the 5th time, the system turns on. All those 5 times, I kept on pressing the ESC key once I powered on the system.
Also, every time I'd a chance I did run the pc doctor to find any pro blem with the board or video card, but every time it turned out to be fine. So now,every time I turn my system off or use a stanby/hibernate whichever turns the screeen off, on immediate reboot it comes out blank but with the power indicator light on.
Here by I also list any changes that I'd made:
1. I reformatted the system and only then this started to occur.
2. after reformatting lsat time, I forgot to change the boot sequence but now I;d fixed that by pressing F9 under startup in bios.
3. I'd also once replaced my RAM with a different one (have 4gb now, but I suppose t60 can support a max of 3gb). WIll this be a problem?
4. And in the recent times due to the ati3duag.dll BSOD has occured. Any idea what this error might be due to?
5. Due to all these uncertainities, I havent updated tot he latest ATI driver which is 8.593 * and I still have the 8.293* . Will updating to the new one be a problem?
I appreciate any help or guidance you can give me in this matter and I badly need to fix it for my projects.
Thanks
Vishak

I think your best way of diagnosing this is to remove the new ram and install only one chip, if the problem persists, try the other. If the problem persists, then I'd try booting from a Linux LiveCD (any will do but I'd recommend ubuntu.com). boot with the option to not change anything on your PC. If you get this same problem when booting linux, then you know it's a hardware problem, in which case I'd remove as much hardware as possible, drives, cards, etc... if it still persists, then you most likely have a bad system board. In this unfortunate event your best option would be a used one. A new one would cost more then the laptop is worth, but used T60 boards are pretty reasonable, I just found one for another member and could probably help you find one to if necessary, but lets hope it's just a ram chip. And by the way, your system is limited to 3GB, but in the chipset, and in your 32bit OS they came installed with. You can install 4GB, but it won't be able to use it all.

Mid-2010 macbook pro has started having "black screens"

apple store diagnosed as "software failure". they wiped it clean & gave me instructions to reinstall/restore from backup at home. successfully reinstalled but another black screen after about an hour.
i am NOT a computer person so i need kindergarten language/instructions/suggestions (fitting, as i was a kinder teacher). i am a 6 hour roundtrip to the apple store, living in a rural town after 35+ years of living in an area of 6 million with MANY apple stores close by.
has this happened to anyone else & if so, can you tell me how you corrected it? again, VERY elementary language please!
thank you!
p.s. i have since upgraded to OS X 10.9.2 & while it's listed that i have vmware fusion (i do), i don't use it...

You may have the mid-2010 problem. There's an issue with the graphics module on that machine. There was a program in place to replace the motherboard within 3 years of purchase, but you're probably outside of that. Some folks have supposedly gotten theirs changed outside of that period, so you can try. There's a very specific test Apple has for this called the VST, which should detect the problem. I don't think all the Genius Bar folks are aware of this issue, so it's best to ask for it specifically. Take along a copy of your kernel panic report if you're getting one.
http://support.apple.com/kb/TS4088?viewlocale=en_US&locale=en_US
What you can do to use it is download gfxstatus from http://gfx.io and force the graphics to Intel. That will lessen the panics at the expense of graphics speed.
You may be eligible for a depot repair, which is a flat rate of about $310. Ask at the Genius Bar.

Boot Camp won't boot Win 7 DVDs /Cloned disks - White cursor flashes once then Black Screen of Death.

Hi Guys,
I am having a serious issue with my machines ability to use boot camp. Here's what happend: I had Win 7 installed on the BOOTCAMP partition for a long while, then one day my HD crashed. So naturally I got my HD replaced from Apple and got Lion reinstalled and wokring flawlessly. Then I planned to get my Boot Camp going again, but my computer has a will against it I swear. So I run Boot Camp Assistant , create the parition and reboot. At this point I have my Win 7 disk burned using Disk utility in the drive, I am using a dvd disk image from Microsofts online store. I reboot and the computer hangs at the "pick a harddrive" grey for a second. Then the DVD drive spins up and I get a black screen, then for ever so slight a moment there is a flash of a white _ a the top left, then flash , nothing, the screen remains illumniated. Now I tried this multiple times , let it run over night , and nothing. Its almost as if my laptop will no longer boot the style of dvd that win 7 is.
Being a diagnostics first type of a person I tested all the variables, the win 7 cd works fine in other macbook pros. My computer boots other mac os x DVDs without a problem. I also tried using winclone to create a copy of another machines Boot Camp and flash it to my BOOT CAMP drive but this has the exact same result! Therefore it seems that the underlying system that runs my Macs ability to boot from Windows-style? partitions and dvd is broken. I also tried installing rEFIt, but that doesn't seem to help. I also tried booting off of an external USB drive with the same result. I tried zapping p-ram , scm and doing all software updates.
Has anyone expereinced anything like this? Anyone found resolution to a similar issue? Any other tricks related to Macs EFI and boot process that I could use to debug this? Anywhere that EFI stores logs possibly?
I went to the Apple's Genius Bar and they were stumped on my issue. I felt that they should be able to fix it considering it booted fine before I had Apple replace my HD.
Thanks to any responders, I'm really hitting my head on the table now and would love some help.

Have you reset the PRAM? It should usually be done when replacing any hardware. Have you got the latest EFI firmware for your Mac?
Not knowing what model /YEAR your MBP is (not that it would help me too much but the other fellas probably would) it's hard to guess as there are issue's for different models. The only thing I could find was it's usually caused by a non-conforming video driver. Microsoft had a page on it I found by accident and now I can't find it!
WinClone hasn't been updated by the original author in over a year, others have tweeked it a little to work with W7 but seems to be semi reliable, so the be aware.
Unless the other MBP's are identical in Model AND year your putting older or incompatible drivers on your MBP. Boot Camp, (especially if your using the drivers on the original install disks, like 10.6 and earlier) will only install for that specific computer. Just like the OS installer.
EDIT:
Oh yeah, are you sure you have the partition formatted the right way, thats another black screen problem.

Random black screen freezes - GPU or PSU issue?

Relevant specs:
Gigabyte Z87
MSI GTX 770 (N770 TF 2GD5/OC) - stock speeds, 335.23 WHQL drivers
i7 4771
750w Antec High Current Gamer
Windows 8.1 Pro 64 bit
For the past three weeks, this setup has been very stable. I then went on vacation for 3 days and then came back. All of a sudden, I then started getting random black screens (which occured in the middle two consecutive LOL matches, I'm quite sure I'm in the tribunal now...). If I'm in the middle of a game, the sound will stutter, and the game/system might appear that it's still playing for a few more seconds even though I can't see anything. I either have to manually reboot, or it'll just restart itself. I don't notice any error message when my system restarts. I tried doing a 3DMARK run to stress-test it, and it black-screened during Fire Strike. Sometimes I'll get a black screen at the Windows desktop doing nothing in particular to stress the card; I even got one in my BIOS setup screen!
This morning, I did a fresh boot and ran GPU-Z. The VDDC graph doesn't look quite right to me, given all the hiccups. Oh, and 5 minutes after that screenshot, another black screen.
The reason I mention the PSU is 1) I noticed that that particular PSU is rated 40A on the 12V rail, and yet the GPU requires at least 42A. but there are two 12V rails on that PSU, for 80A, which should be more than sufficient, and 2) I didn't notice any artifacts prior to any black screen. It's just weird that these would happening out of the blue - it sounds like the kind of issue that would've been present on day 1.
Any thoughts?

I have the same issues.
Specs:
I7-4771
ASRock B85M Pro4
MSI GeForce GTX 750 [N750 TF 1GD5/OC]
Super Flower Golden King SF-550P14PE 550W
Windows 8.1 Pro 64bit
Same thing on Windows 7 Ultimate 64bit
Tried both WHQL and beta drivers. This is the second GTX 750 with the same issues, my first card was replaced.

Windows 8 black screen after Dell logo?

My computer was being really slow the past couple of days so i did a system scan with reg cure pro and it told me i had to restart my laptop. After restarting my laptop it showed
the dell logo and then just a black screen. Every time i restart my laptop it does the same logo then black screen. When i click the power button it turns of instantly instead of the usual 3 or so seconds of holding the button. I have looked up this issue
but have not found a fix.I cannot/do not know how to restore windows 8 because ,y laptop came without the installation disk and when i try to access the advanced settings it is still just another black screen with the words "f12 boot
options" in the bottom right corner. I have also seen people talking about 2 different styles of this black screen. One with a black screen but a light border and the second just a black screen. The one mine seems to be is that there is a bright border
along the edges of my laptop screen but black everywhere else. If you have found a fix to this problem or have a temporary solution please post a comment. Thank you.

Issue already solved from Dell inspiron n5110 Series, Follow the step to get your screen at better resolution....
1. Install Windows 8 Pro
2. Use External Monitor to View the Screen of Windows 8 After Installation or Run in Safe Mode To Access Windows 8 at Low Screen Resolution
3. Download the Bios Driver (New one) for your Laptop from Dell.com website,
4. Install the Bios ( Remember to connect the AC and DC )
5. Once Bios Installed and system Restarted you can disconnect the External Monitor if you did attached
6. That is Done, Now you have a Windows 8 in your Dell inspiron

Black Screen - Get Chime - Can Boot off HDD using another Mac - iMac 24in.

Hope someone can help me here, as I'm at my wits end.
I've got two issues, one with my MacBook Pro 17in, 4GB RAM, 160GB 7200rpm (2008) and another with my iMac 24in. 4GB RAM, 500GB 7200rpm (2009).
Firstly the MBP, left work on Thursday last week, got home, powered up the MBP and got a black screen!!! Tried resetting PRAM, SMC, booting in safe mode, removing and re-installing RAM, removing battery and mains power and leaving off overnight etc etc, yet nothing happens. Benn all over the forums and have not found any solution to get my beloved MBP working on it's own. I can boot off the HDD using another MBP 15in, re-install Snow Leopard and as far as I can tell the HDD is fine, as I have run disk utility and it tells me the HDD is OK.
I can't figure this out and it's doing my head in, as I use this laptop for business use and just can't afford to go out and buy another Mac. I should point out that this MBP never had any issues when running on Leopard, but ever since I upgraded to Snow Leopard, I have had nothing, but trouble. I did a clean install, in fact I have done it at least twice, even erasing the HDD securely, both at 7pass and 35pass, yet I have had permissions issues regularly and on the odd occasion, I have also had the problem of the HDD not being recognised.
The iMac is nearly the same, but the screen is working, although the iMac doesn't see the HDD no matter what way I do, again, reset PRAM, SMC, safe boot etc etc. In truth the iMac has been a lot more unreliable, but with the screen working, if I can get any solutions here, then I'll be working to work on that without the need or hassle of working via another.
I think that the MBP is only just still under warranty, but the iMac definitely is, but I need at least one working for business use, so really only want to let Apple have one at a time to look at/repair etc.
Ideally, as the HDD is working in the MBP, if I could get a solution to the black screen issue, then I could do without the iMac for whatever time it takes, so if there is anyone out there that can help, I'd be so grateful.
One last thing, when I bought the iMac 24in., I also bought an iMac 20in., but I never upgraded the 20in. to Snow Leopard and to this day, it has worked flawlessly, without a single issue ever.
Perhaps, I'm getting paranoid here, but there seems to me to be a link between the ongoing and regularly occurring problems with both Macs ant the upgrade to Snow Leopard. Why also, or is it just pure unadulterated coincidence that both the MBP and the iMac 24in have failed at pretty much the same time??!!!!
I'm going mental here, so I hope someone out there has a better fix, then me overdosing on Prozac!!
PS
I'm not a mac expert, not good with a soldering iron either, but I'm capable of following good instructions.

Using Snow Leopard forum is probably your best bet.
I don't care if someone has 20+ yrs, I still like having a good troubleshooting book/manual handy.
Mac: can't get by without bootable backups, even if you use TimeMachine, clone your system. Save you all this fuss and work.
Then invest in high quality disk repair and maintenance program.
Disk Warrior / TechTool Pro 5 / Drive Genius 3 - top 3 probably
There are always going to be normal items you just ignore with Repair Permissions. Useful to do once in a while but not magic. Same with SMC and the rest. Running disk repair is one of those things that it seems should be done before there is trouble, not after, and a weakness in HFS file system and disk directory.
Apple Support is a good place to start looking and then hardware category.
http://www.apple.com/support
http://www.apple.com/support/imac /macbookpro etc
Make sure all your software is current, don't install anything you are unsure of or can do without.
Run Apple Hardware Test off your OEM DVD specific to the Mac.
Now, have you Googled for this?
have you looked at reports about 500GB drives used in some Macs that had issues and were offered firmware update for the drive?
Considered just using another drive connected to iMac?
You can overheat a hard drive with needlessly running 7 and 35-write pass, besides which the best way to map out bad blocks is not Disk Utility.

I'd direct your replies to iMac and MacBook Pro as well as to Using OS X Snow Leopard areas.

Black Screen on MBP, Can hear chime and can boot from HDD via another MBP!

Concerning your imac, have you tried installing the OS on an external drive and running the iMac from that? My friend in Texas had her iMac's hard drive vanish, so we installed the OS on an external FireWire drive I happened to have and then restored her data from a recent backup. So far I haven't had time to install the drive in her iMac, so it's been running off of the external for a long time now. Perhaps you could do something like that so you could at least have the use of the iMac while your MBP is in the shop. Once you get the MBP back, you can send in the iMac.
Be sure to report both of these to Apple and get case numbers so that you can document that the issues started while you were still under warranty--especially for the MBP that's about to go out of warranty.
Good luck!

Would like to know if I can connect a macbook pro and link to a PC in any way and still access the macbook pro's files. Display is out/have black screen. I want to back up before I send for repair, but don't own another mac to restart 7.

Is there any way to connect my 2011 macbook pro to my PC laptop (Dell) so that I can get files off of the Mac? The display on the pro is out and I've got a black screen. The computer turns on. Actually it turned on one time after many tries and when I took it the Mac store the guy hit restart before I could stop him. I don't have another Mac to back up files to in restart 7 mode and I can't see my external hard drive to copy to when the computer has no display, so I am at a loss on how to get the files. I would like to get them before I send in for repairs. Any suggestions are appreciated.

The only other thing I can think of is to pull the drive out and hook it to another machine with a USB enclosure. Something like this:
http://www.amazon.com/Vantec-NexStar-2-5-Inch-External-Enclosure/dp/B002JQNXZC/r ef=sr_1_2?ie=UTF8&qid=1388312417&sr=8-2&keywords=2.5+enclosure
Then you could read it like an external USB drive. It's easy to open up and get the drive out.

Why do I get a black screen if I multitask to another app and then return to Facetime during a call?

Whenever I swap to another application from Facetime during a call, I get a black screen when I return to Facetime and I am forced to end the call by hitting the Sleep/Wake button. Help!
