HT1349 there is power, but the screen just went black

i have a mac pro that has power, but the screen went black. has anyone else had this problem?

Hello Gail,
It sounds like you can hear your Mac start up, but you do not see anything on the screen. I definitely understand your concern with this.
I found an article with steps to troubleshoot issues with displays. This article is for internal and external displays. I wasn't sure if you were using a Mac Pro or MacBook Pro from your post. If you are using a Mac Pro, follow the steps for external displays, but if you're using a MacBook Pro, follow the steps for internal displays. I recommend reviewing the full article, but this step specifically stands out to me for the issue you described:
Reset the system
You can reset the Mac's parameter RAM and SMC.

Thank you for posting in the Apple Support Communities.
Best,

Imac G5 will not boot up. there is power but the screen is black. About 30 sec after turning it on, the fan comes on loudly.

I have an old imac G5 (non Intel) The screen went blank but the fan turns very loudly. I cannot reboot the computer. whenever I start it I get power and black screen and the fan comes on loudly after about 30 secs. I have tried rebooting pressing varius keys, but no luck. I once got the flashing question mark, but I can't get that either. I'd like to reboot from the disc, but I cannot insert a disc. Any help out there??

If zapping the PRAM does not get it working, it's time for a new iMac. Repairs will not be worth the cost. Put it towards a new iMac.
I've been there, done that. Had my burial last summer.

What do I do if my iPod touch 8g 4g has a white screen after screen replacement ? I tried holding down the volume up button, the power button, and the home button all at the same time but my screen just went black and it wont turn on.

it just wont turn on after repair on the screen

If it never worked after the screen replacement then it would appear that you have a hardware problem either caused by the repair or the problem that lead to the screen replacement.

My MacBook was working completely fine , I've had no troubles with it. I was waitin for something to load and all of the sudden the screen just went black . I've restarted it several times and the screen has just stopped working .

Try typing in your 10 didget cell number. Restart iPhone to get the prompt again.

I went to use my iPhone 5 (I had used it just minutes before) and it wouldn't work. It was about half charged and seems to have shut itself off. I tried charging it and turning it on but the screen remains completely black. What happened?

Try resetting. Hold the sleep wake button (on the top edge), and the home button (round button on the front with the white square) at the same time for 10-15 seconds. If you see the apple logo, let go. Your phone should restart. If not?

The screen on my iPhone 4 turned black while i was using it-it was not dropped or damaged in anyway. The phone itself is still working as it comes up in itunes when I plug the phone into my computer, but the screen is completley black. What can I do?

The screen on my iPhone has gone black while I was using it. It just "shut off". The phone is still working as I can hear/see it when it plugs into the computer, but the screen just wont turn on. I've tried the soft reset "holding down home and lock screen" and i've tried to restore settings. I went to the apple store and they said I had to send it to my provider (in another country) but my phone contract has run out.
Is there a way to fix this?
If not, is there some way apple can replace the phone? It's less than 2 years old. Surely the screen shouldn't just give out like that.
Thank you

I have an iphone 4s that is having display issues. If I turn the phone on, it vibrates to acknowledge it successfully turned on but the screen stays solid black. I can plug the phone into my computer and itunes will recognize the phone as well.

However, itunes can not do anything with the phone because the phone is locked and I can not unlock the phone because the screen is black.

The screen does work though! Through trial and error along side a little troubleshooting, I was able to figure out that the screen will cut on after the phone dies completely. The phone has to die completely with no battery power left. Then if I plug the phone into a charge and wait a while for it to charge, the phone will turn on like nothing was ever even wrong with it. I charge the phone up to like 30% and turn it off then bam the phone turns on but the screen is solid black again.
I am currently in the process of waiting for the phone to die and when I turn the phone back on I am going to completely remove the auto-lock and lock code off of the phone for the time being.
Any other suggestions? Please help!

Sounds like the device was dropped at some point and damaged as a result.
Take it to Apple for evaluation and a replacement.

New iPhone 5c keeps beeping and the screen just stays black.

new iPhone 5c keeps beeping and the screen just stays black?

Plug your device into the original charger & block in a wall outlet and leave it alone for a couple of hours. Then, while it is still plugged in, restart it by holding down the home button and the power button for 10-15 seconds until you see the Apple, then let go.

What is wrong with my 30" Cinema Display? The USB and FireWire ports still work, but the screen is pitch black. When you plug it into the computer, it detects that it's a Cinema Display.

For some reason, the USB and FireWire ports still work.

If you shine a really bright light directly into the screen can you then see a faint image on the screen? If so, that would indicate the backlight has died (hardware failure) and the unit needs repairing.
