Screen is black although the computer is running

I pit my computer to sleep yesterday and when I opened it up to use it the screen stayed black although it sounds like it's running in the back ground. I tried restarting and removing the battery. Any other suggestions? And yes I also tried the Screen brightness buttons. My MacBook is the older generation for 2008 I'm not sure if it's just finally hit its peak. Thanks
im also not sure about the system but I think it's running on snow leopard.

My MacBook is the older generation for 2008
Assuming you mean Macbook Pro See Articles: http://support.apple.com/kb/TS2377 MacBook Pro: Distorted video or no video issues
These computers were manufactured between approximately May 2007 and September 2008.
If your model MBP matches the ones mentioned in the KB Article (the program has expired) strongly suggest that you call Apple Customer Relations - 1-800-275-2273. Ask politely & firmly that you want to be transferred to Customer Relations. Tell them exactly what you stated in your post.
CR is still honoring the program on a CASE BY CASE basis.
GOOD LUCK!

On start up my screen is black and the computer beeps 3 times

Last time I used my MacBook air the screen went black and the computer shutdown on it's own. On start up the screen remains black and the computer beeps three times intermittently. Does anyone know how I can fix the problem? Thanks in advance.

Send it to an AASP or Apple Store for repair.

The screen turns black and the computer stays on

hi,
Once in a while when I am on my beige power macintosh and it runs smoothly, it all of a suddenly stops what it is doing and the screen turns black. when I am on iTunes some times, the screen turns black but the music still plays. I unplug and replug the monitor in but it is still black. Here are my computer stats. Ram 320mb, OS 10.2.8, 8 gig hard drive, 6mb vram, built in video, USB & Firewire PCI cards, and an AV Personality Card w/ 28k Modem, Running 333 mhz, and I have tried 3 other mother boards

Welcome Jarrett,
The article implies that using a certain version or "build" of the 10.2.8 updater fixes the problem. No true. Almost everyone who's experienced it on a Beige G3 has used the preferred updater specified in that article.
Not every Beige gets it. I had 640MB when I moved to 10.2.8 and it never hiccuped. However, I run video off a PCI accelerator card and, as Frank mentioned, the video issue seems to happen when you are using the logic board video port.
If you can't get your computer to boot and run long enough to use Terminal, pop it open and pull RAM until its under 192MB. Then the computer should be stable long enough to do the fix. Then you can add the pulled RAM back.
The good new is that everyone seems to have permanently fixed the problem by applying the Terminal procedure described.

MacBook Pro display won't turn on. Screen is black meanwhile the computer is on.

Screen is completely black. When I try hooking it up to an external monitor, no signal is detected on the other monitor either. So now I have no way to see my screen.

Mid-2010 15" MacBook Pros - the bad NVIDIA GPU
If you're having frequent kernel panics with your 15" mid-2010, or intermittent screen problems, the problem is, more than likely, the faulty NVIDIA GPU found in a number of those machines.
Here's just a sample of a kernel panic log that points to the faulty NVIDIA card:
Kernel Extensions in backtrace (with dependencies):
         com.apple.GeForce(6.4.0)@0x82ac4000->0x82b7afff
            dependency: com.apple.NVDAResman(6.4.0)@0x834a0000

            dependency: com.apple.iokit.IOGraphicsFamily(2.2.1)@0x8301b000
Here's the "official" Apple take on the issue - but the very real kernel panics need not be preceded by 'Intermittent black screen or loss of video'... in fact, you might not experience any video problems at all. Although video problems can certainly be a portent of things to come…
So what can you do? Print out a copy of your kernel panic and a copy of the Knowledge Base article and take them, along with your machine, to your local Apple Store or an Apple Authorized Service Provider. The unfortunate thing is that many people have passed the “three years from date of purchase” now and Apple is not honoring the free logic board replacement for many users. Some dealers seem to be making some exceptions for those past the three year mark, but don’t count on it…
Good luck,
Clinton

Iphone 4 makes calls but screen is black and the power button doesnt work. never synced to computer or photo stream. I dont want to lose my photos

So, my Iphone 4 now has a black screen. Before it did this I unlocked the screen (which has a passcode) try to open instagram and the screen flashed and went black. I can make calls and it seems to send messages but I dont know for sure because the screen is black. The power button (sleep) does not work and when I try to reset the phone it makes a call. I never synced it to a computer or Itunes and I didnt start photo stream. I want to preserve the pictures because it has photos of family members that have passed. Is there a way to get the photos?? Help please!

If you have attempted the reset, which is holding the home button and sleep/wake button, was it still connected to the computer? Have you tried to do that when not connected. You stated it never came on, how long did you hold the buttons together? If you cannot get it to connect to iTunes then you would not be able to restore the device. You can see if you can put the device into Recovery Mode by following the instructions in this support document. If that does not work, then you are correct, make an appointment at the Apple Store. If you can't update or restore your iOS device

Can you start Firefox in [[Safe mode]] ?
You can also do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
You can initially skip the step to create a new profile, that may not necessary for this issue.

Screen goes black, shut the lid for a few minutes, open the lid the turn on chime comes on and the screen comes back to life. The computer itself has continued to update just no screen. After a few minutes goes black again. Is logic board going bad?

Screen goes black, shut the lid for a few minutes, open the lid the turn on chime comes on and the screen comes back to life. The computer itself has continued to update just no screen. After a few minutes goes black again. Is logic board going bad or graphic card issue? Trying to decide if computer is worth repairing as it was made in 2007.

It does sound like you might have a faulty video connection. See if you can make a Genius Bar appointment at your local Apple Store.

If you didn't back up the phone to iCloud or iTunes (on your computer) BEFORE attempting the update, the data will be lost.

Since you have Lion v10.7.4 installed, use Lion Recovery to repair the startup disk if necessary, or reinstall the Mac OS X.

Close your iTunes,
Go to command Prompt -
(Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
(Win XP SP2 & above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt
In the "Command Prompt" screen, type in
netsh winsock reset
Hit "ENTER" key
Restart your computer.
If you do get a prompt after restart windows to remap LSP, just click NO.
Now launch your iTunes and see if it is working now.
If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:

I'm also having a music issue. When my phone is attached to the computer (mac running 10.6.8) it looks like my music is there but its gray and I can't play anything. I've tried to delete it and it won't let me but it does not show up on my phone.

By the way, I have tried shutting of the display switching in the power settings. That was basically the only real answer I found anywhere. It didn't work.

I can not get my iPad to mirror on Apple TV. When I toggle the tv screen goes black and the iPad freezes. Have updated the iOS to latest settings and also updated the settings on the Apple TV

Welcome to the Apple Community.
Try the following steps, check whether things are working after each step where appropriate, before trying the next.
Check AirPlay is turned on on the Apple TV (turn it off and on if it already is)
Check that both devices are on the same network (Settings > Wifi, on the mobile device and Settings > General > Network, on the Apple TV).
Restart the Apple TV (Settings > General > Restart).
Restart the Apple TV by removing ALL the cables for 30 seconds.
Restart your router. (Also try removing it’s power cord for at least 30 seconds)
Restart your mobile device.
