It's possible you have a bad RAM chip, try running Apple Hardware Test on your system.

Apple guarantees their work, take it back.

My iPod touch won't turn on. I have tried plugging it in to charge, but and the screen remains black. I have tried restarting/resetting it to no avail. I would really appreciate your help. Thank you.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

IMac screen goes black after 1+ hours of use and we can't get out of this.

I have a mid-2007 iMac. When anyone is on the computer for approximately 1-1.5 hours, the screen goes black and we cannot get out of this. There are no time restrictions or power-saver settings on. Can anyone help me with this issue?

You cannot do anything with the iPad until you do as instructed by the iPad and connect to iTunes on a computer.
You probably need to restore the iPad and the only way to do that is via iTunes on a computer.
Take it to an Apple Store and ask for help at a Genius bar or take it to a friend's house that is running iTunes on their computer and try to restore it.
You will lose all of your data and settings now because you never backed the iPad up in the past.

External Monitor with iTunes - iMac screen goes black

I have an iMac with iTunes 7.7/Leopard and an external VGA monitor (I use the standard Apple mini-DVI to VGA converter) then I use the external monitor to watch video from my iTunes library.
All works well - I have my desktop spread over both monitors, I fire up a movie from iTunes, move the video window across to the external monitor and everything is good - I can watch the video on the external monitor whilst continuing to work on my Mac - the iMac screen displays the Mac desktop as normal.
However, if I put the movie into fullscreen mode (view -> fullscreen on the iTunes menu), the external monitor displays the movie in fullscreen mode as it should, however the iMac monitor goes black.
The only way to fix this is to exit fullscreen mode and go back to one of the view options (rg fit to screen).
Any ideas how I can have my external monitor in fullscreen mode and have my desktop back?
Many thanks

My brand new iMac screen goes black intermittently...

Hi - I bought my 27" iMac about 3 months ago and pretty much since I got it occassionaly the screen goes black. I'll be working away and all of a sudden it goes black. After a few seconds it comes back on, but this can't be good? I asked my local computer guy and he said it was a known issue due to safari and not to use safari. That seemed to fix it but A) I like Safari and B) it's started happening now even when I'm not in Safari. Any ideas?
iMac 3.4GHz Intel Core i7, 8GB ram, Graphics AMD Radeon HD 6970M 1024 MB, OS X 10.8.2

I asked my local computer guy and he said it was a known issue due to safari and not to use safari.
That's ridiculous. Take it in for warranty service.

24" 2008 iMac screen going black

My 24" 2008 iMac screen keeps going black then coming back after a while. What temperature would it need to get to in order to knock out the display? I have iStat.
Also, if the screen fails due to graphics card or other component, is it possible to connect an external display to use it until I can upgrade to a mini?
Cheers.

As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.

Imac screens goes black

My 2007 Imac's screen started going black. I can hear it still running, and even hear sounds from programs. After awhile though I can no longer hear the progams. but it still sounds like its running. It happens when I open games apparently, hasn't done so with just browsers and itunes open.
I'm guessing it's a graphics card but wanted to be sure. I have an ATI Radeon HD2600 256MB. Can I replace the card on this machine?

ok, my screen has now gone black it wont come back on, looked on utube, there is a vid on there how to fix this problem, tried it, didn't work, so i found a workaround, thunderbolt connector to DVI, i think its called (thunderbolt to another monitor) bought this cable, £20 from PC World, apple store 1 hr drive, PC world 15 mins, found a spare monitor, plugged all in, nothing worked, both screens black , but then pressed COMMAND F1 BOOOOOOOM ............... only joking spare monitor is mirroring the iMac screen, so all working again till i can get a replacement screen.

HT201177 IMac screen goes black and will not return without power cycle. Time of events 19 min to 43 seconds after desktop shows

Display goes black
19 min is longest it lasts goes down to 43 seconds after desktop appears
Just updated to Mt Lion same time this started
I am guessing video card went out at same time?
Do not have D test for hardware after upgrade.

Suggestions?

I did some more digging, it appears to be a backlight problem only. I can see the screen very dimly if I use a bright flashlight in a very dark room. It also seems to run ok if the brightness is turned down a LOT.
So I'm thinking this is a LED driver board issue or the display itself. I'll open it up and check the connection between the two and see if I can get any more clues. At least I can use it somewhat now by dimming the display significantly...

My display suddenly turns off (goes black), nothing works, have to restart using power the button.

Hi all
In both Snow Leopard and Lion, it sometimes (rather rarely) happens. Specially when the system tries to use a litle bit more of the graphics performance - such as using Mission Control, opening Adobe Photoshop, using Quick Preview (pressing the space key) - the display very suddenly goes black, or turns off. In this phase, absolutely nothing works ! No sound, no response to pressing any of the keys on the keyboard, NOTHING! Not even the keyboard backlit adjustment keys (F5 & F6) do any good.
And what I do is to press and hold the power button to turn the dead device, off and start it up again.
What I did to solve this problem which didn't work at all:
1- Since the problem occurs when using more graphics performance, I reckon this might have something to do with the graphic switching... . so I unchecked the "Automatic Graphic Switching" in both Snow Leopard & Lion, but still the same thing happened a few times.
2- I did reset the P-RAM and SMC (whatever they are) in Snow Leopard. No difference !
3- I changed from Snow Leopard to Lion, which is currently installed on the device.
None of the above could solve this annoying and devastating problem.
I'm too afraid that this is a hardware related issue. If so, then any of the two graphic chipsets, or even the mainboard might be damaged I guess ?
Does anyone have seen such thing and happened to solve it somehow? I would REALLY appreciate if you could share the solution. Any kinda guidance, helping to find out the reason of this, would be such a relief !
So thank you, in advanced

Oh ! One thing I forgot to mention...
And that is, I tested the hardware twice, using Apple Hardware Test, in both quick and extended modes.
p.s.:
The "problem" happened three times in the last 30 minutes. I've been using Photoshop. Thank god everything got recovered....
I desprately need help here guys !!

20" Imac Screen Goes Black After Start Up?

A few days ago my screen went black and stays black. It is a 20" intel core 2.0 duo processor Model #A1224. Serial # W8740 which I guess means it was built in the 40th week of 2007. When I restart the screen comes on for only a second or two and then returns to black, every time. I know the computer is booting as I can hear it working and if I look very close at the screen I can see windows open and if I hit the space bar I can faintly see the windows highlighting but the screen is very much black and the windows are barely visible. I can also turn the volume up and down and hear it. I have tried all the different resets suggested in the related discussions and have removed and replaced the ram, nothing has worked. From researching I am guessing it is one of two things. Either the video card attached to the logic board which sounds too much to have replaced or possibly the lcd display. However none of the other topics I have found have the exact same symptoms so I am not sure what the problem is. I do not have coverage as its a 2007 computer. I found a lcd for around $130 and think I can replace it but am not sure if this is the problem. Also apparently I would need a different lcd if the current one is made by lg, but the only way to find that out is to take the current one out and look at it. I don't want to do that unless I am sure its the display. Any suggestions or related issues would be very helpful. I am probably due for a new computer but don't want to lose everything on my current computer, it is my personal and business computer and holds a lot of important info and applications.
Thanks in advance!!

Any suggestions?

10.8.3 iMac screen goes black, unresponsive

This is happening more and more often.
During regular use, the screen will go black (not off, because I can see a faint glow around the edges) and it becomes completely unresponsive. In addition, I just learned that it will not charge my iPhone when this happens so I guess the USB ports are dead as well.
A couple weeks ago I had 2 instances of the crazy video flickering and jumble so I thought it was a video card issue. Now with the addition of the iPhone/USB thing, I can't be sure.
When I restart the computer by holding down the power button for 5 seconds, it starts up fine and the phone will charge again. This is going to become a real problem as I'm sure I'm frying the computer's brain evey time I have to do this and I'm going to start losing data. Thoughts?
Here's the config:
iMac 27" 3.4 Core i7
OS 10.8.3
12 Gig Ram
Radeon 6970M 2048M
Thanks for your help.

First, try resetting the PRAM > About NVRAM anrd PRAM
If that doesn't help, Reset the System Management Controller (SMC)

If nothing above helped, could be a bad graphics or video card. Run the OS X Mountain Lion: Apple Hardware Test

IBook screen goes black after unplugging power cord

I originally posted this topic in the wrong discussion group for iMac G4, the computer is actually an iBook G4.
My wife's iBook bought about 2 years ago shows battery 100 percent charged. But when she unplugs the power cord the screen goes black. Can not be restarted until she plugs in the power cord. It seems like it might be the battery. She got extra batteries when she bought it. Is there a way to tell if it is the battery before having to replace it?

Did you check on the status of your battery using "About this Mac" under the Apple on the menu bar? Click on "More Info..." and select Power under Hardware. It will tell you capacity and cycle count.
You may have a dead battery.

Quantum TV Screen Goes Black & Requires Reset

When I first turn on the tv and set top box, the screen says to press the menu button and when I do the screen goes black. I have to reset the box by unplugging. Once it reinitializes it works fine. This has happened 3 days in a row.

Since you can pull up the menu even though the screen goes black, run a self diagnostic to see what the signal is like after the screen goes black. Menu > Customer Support > Top Support Tools > Self Diagnostics
If everything comes back in the green and the OOB signal isnt low then the next step would be to check coax cables and any splitters.
If you are using an hdmi cable you could try either a new one or try switching to component to see if the issue happens again, but since you can pull up menus even though the screen goes black I highly doubt that is the issue.
If none of this helps then a call to tech support would be the next step. You might need to replace the box.
