Screen froze when closing Safari then went black. Am I in trouble?

Have had this iMac since 2004, NEVER had any problems. Went to close window from Safari, screen froze, wouldn't turn off. Had to unplug, when I turned it back on the screen reloaded with the Apple icon then went black. Am I looking at a dead machine?

1) You should run disk utility from your install dvd.
      a) fix the disk
      b) update your permissions.
2) Try a safe boot.
     Shutdown your machine. Hold down the shift key. Poweron. Wait awhile; wait awhile while you harddrive
     is being checked.

3) Another way to correct filesystem problems is into single use mode.
     This page will tell you how to get into single user mode.

    Basically, you hold down the command + s key then powering on your machine. The command key
    has a little apple symbol on the lower left. It is between the alt/option key and the space bar.
4) Run hardware diagnostics. It's good for a sanity check.

IBook screen flickered then went black

Hi.
I have a 12" white opaque iBook (running OS 10.2...it was a hand me down, 700 mhz as I recall. Model is A1005) whose screen began to flicker, then went black. It wouldn't restart. After the usual panicking, I tried to restart with Disk Warrior (which was never installed onto that computer)
Next attempt to fix was to start in safe mode. Nothing changed.
I zapped the PRAM and then the screen came back. I backed up whatever I thought I didn't already have backed up. Feeling quite happy, I treated myself to some baked goods, then I shut it down.
Next day, I got only a black screen and then had to force quit by holding the power button down.
I tried 3 times to zap the PRAM, and still have only a black sceen.
Any ideas on what to do besides using the previously happy iBook as a coaster?
Thanks for any help!

Hi, and welcome to Apple Discussions.

It also sounds like it is possible that it may be having logic board problems. Enough Dual USB G3 iBooks suffered from the logic board problem that Apple began the iBook Logic Board Repair Extension Program in January of 2004. Do the symptoms look familiar? After leaving it sit overnight, does squeezing the case to the left of the trackpad allow you to start up and work for a bit as long as you keep the pressure on it there? If so, you may want to consider trying the shim fix suggested by John Sawyer here in the Apple Discussions iBook G3 (Dual USB) Forum:
[Y]ou can often fix this yourself by removing the iBook's bottom housing, and placing a shim of any sort, about 1mm to 1.5mm thick, onto the raised square on the bottom shield. I use a Scotch mounting square--you can get them in hardware stores and many grocery stores. When you reinstall the bottom case, it will press against this shim, which will press against the graphics chip, and may allow the chip to come into better contact with the logic board.

My iMac screen went pixilated then went black

Hey!
So earlier tonight my 27" iMac (2009) went pixilated (green, yellow, blue, white small pixels) then the screen went black, but the computer was still running. I shut it down and turned it back on and I didn't have a problem until recently. After clicking play on a video on Facebook, the pixels returned and the screen went black again. I then proceeded to shut the computer down, but when I turned it back on, this is what I saw (refer to picture, sorry it's upsidedown)
The lines eventually disappeared along with the Apple logo, but the screen remained white for at least five minutes. I restarted my mac again, but the lines returned and the screen stayed white. That was around ten minutes ago and the screen is still white. What's wrong here?
Also, I recently upgraded to Mountain Lion about two months or so ago from Snow Leopard (either 10.8 or 10.8.1) if that's important at all.

Exact same thing has just happened to me! I believe I clicked on a facebook video as well; same pinkish strips and same white screen. My life and business is in this computer!

Won't turn on - initially saw the connect to itunes screen then went black and won't do anything

Charged IPad all morning - saw the screen that says to connect to ITunes - Once it reached full charge, screen went black and nothing works -

I have tried every reset tip on-line - Hold home and power for 10 secs, 15 secs, alternate, etc. Any other suggestions?

Screen flickered, then went black (faint windows can still be seen)

i was just working on my powerbook and my screen flickered on and off and turned black. the best way to describe this is like what a lightbulb does right before it blows out. what is wrong?! i am trying to type this as fast as i can before it starts doing it again. is my LCD frying?

Might be bad Power Management Unit settings - following instructions to reset PMU.
Otherwise, there are 3 likely hardware related causes:
1. Failing LCD Display backlight - needs replacement
2. Broken/Intermittent ribbon connection - needs soldering and/or replacement
3. Failing LCD backlight Inverter - needs soldering and/or repalcement
For all 3 of these screen would require service for technician....call Apple if you have warranty.

Wake from sleep - screen briefly comes on and then goes black

I have a late 2010 mbp 17" model with no issues until last night.
I have my computer plugged in, and when it's not in use I close the display down and the computer enters sleep mode. When waking it from sleep, the screen will briefly come on and then go black. After a few opening and closings of the display, the display will remain on - the number of times opening and closing the display varies before it remains on.
An easier solution I just tried is by unplugging the computer from power - the display comes right on and remains that way.
When the display goes out, the keyboard backlight remains lit.
The only thing I recall that would have any sort of adverse affect on this is the static electricity that I had with this yesterday or the day before. I live in a dry climate and was shocked when I touched the computer the other day. Nothing really bad, but could this be the culprit? Again, I have never had any issues like this before.
Is there a solution to this? Within the energy saver, the settings (except the amount of time before the computer/display goes to sleep) is identical for both powered and battery sources.
Thank you for any help.

To add, I have tried the following:
Open Terminal
Type the following:
     pmset -g | grep hibernatemode
It should say something like:
     hibernatemode 3
Here's an explanation of the different types of hibernate modes:
0 - Old style sleep mode, with RAM powered on while sleeping, safe sleep disabled, and super-fast wake.
1 - Hibernation mode, with RAM contents written to disk, system totally shut down while “sleeping,” and slower wake up, due to reading the contents of RAM off the hard drive.
3 - The default mode on machines introduced since about fall 2005. RAM is powered on while sleeping, but RAM contents are also written to disk before sleeping. In the event of total power loss, the system enters hibernation mode automatically.
5 - This is the same as mode 1, but it’s for those using secure virtual memory (in System Preferences -> Security).
7 - This is the same as mode 3, but it’s for those using secure virtual memory.
To change your sleep mode, use the following command:
     sudo pmset -a hibernatemode 0
(replace 0 with whatever hibernate mode you desire)"
Also - the white light that comes on while in sleep mode on the front right of the computer does not fade in and out like it used to...
Gah, I don't like issues

My iphone6 started to flicker then went black, its on i just cant see it

I was just on youtube, when the screen on my ihpone 6 (128GB) started to flicker then white thin lines appeared all over the screen (vertically) and then the screen went black. It's still on but I cant see the screen as its black and doesn't show anything.
No I haven't spilt water on it or any other liquid.
No I haven't dropped it, nor is the screen cracked, scratched or damaged in any way im very careful with my stuff.
I just need an answer, or at least an idea to what has happened, thank you.

Dont know what happened but I would try a reset, hold thee power button and home button until you see the apple then let go.

How can I fix my iPod that the screen shows the apple logo then goes black then back and will NOT connect to iTunes?

I turned off my iPod then turned it back on. The normal apple logo appeared on the screen but then it went black and it won't connect to my iTunes. What should I do and what are my opptions.

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 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.

Screen popping when closing--2012 Macbook Air

Is it normal for the screen or hinge to make a popping sound sometimes when closing the lid? Particularly after extended periods of use, my MBA's screen will make a soft popping noise as I start to close the lid; I can also feel the popping in my hand if I put my whole hand on the back of the lid to close it. It almost sounds like someone popping their knuckles, except it is just one soft pop. Other than that, closing the screen feels fine.

no one knows until Apple announces it.

Movement of the screen/top when closed

Noticed something while wiping the top of the MB. When closed, there is some give/movement of the "lid" of the MB. When pressing left and right at the front corners of the computer the lid seems to move slightly. When I open the computer slightly however, there is no movement. I'm wondering if this just has something to do with the magnetic latches, or is this a defect. When the computer is fully open there is absolutely no movement of the screen.
Anyone have any suggestions?? Thanks in advance for your help.

If u live near a store i say bring it back if its within 12mths and show them first hand what is happening. I have a feeling you wont be the first and they should swap.

HT2674 made a phone call this morning and my phone vibrated then went black like it turnt off now cant turn it on. what is wrong with my Iphone 4S

my iphone 4S went black this morning after making a phone call and the phone will not turn on. what is wrong with my phone?

I switched the usb port and did the whole recovery holding of the buttons ect... And it worked, the computer detected the phone and i was able to click restore. However, the computer says preparing iphone for restore and it is still doing the restarting thing where the apple fades away and then comes back like it is restarting. If i can somehow get past this i will be able to go back to factory settings and resolve my problem, but this is where i am stuck.

My late 2007 MacBook Pro starts but all the screen does is flash once then go black.

My late MacBook Pro 07 blinks then goes black, I just replace the hard drive. What should Ido

There is a known issue with the Nvidea GeForce 8600M GT video chipset in that model. Nvidea sold Apple and other companies bad chips that failed usually from heat issues. The only fix is a complete logic board replacement, and I found new, known-good boards are hard to get.
Apple had a repair program that fixed this at no cost for four years from data of purchase; it expired in Dec 1012. Mine died at 5-1/2 year after purchase. You should plan on getting a new computer as the chances of finding a proper replacement board are now getting thin.
Some people may suggest using an external dispaly but that will not work with this failure mode.
I was able to start mine in FireWire Target Disk Mode and connected it to my iMac. I could see and recover files.
