Screen goes dark..not black

Hi
Last night my computer screen went dark. I could still see what was on the screen but it was very very dark. Had to force quit with power button. Computer came back on and was fine. Now this morning when I went to power on, it powered on fine then a few minutes later same thing happened. It happened a few times and then the last time I powered up it hasn't happened. Any suggestions?
Thanks
Update: happened a couple of times today.

Same thing here. Started happening a few days ago. Usually, all I have to do is close the laptop and open it up...doesn't usually work the first time, but after 2 or 3 times, it will come back on and there is no problem. I have no idea what is going on. Mine is a 2008 macbook.

Macbook screen goes dark (not to sleep)

So then I have to fiddle with the down (F1) and up (F2) buttons til it comes back on, then it immediately goes dark again, this happens several times a day now.
I need a new LCD screen right? I got an estimate from my local Mac repair guy, he said $150 for the screen and 50 for labor--does this sound right?
Have MacBook 13" 10.7.4. Got it 4 years ago.
Thanks!

I've been having a similar problem. I haven't found a permanent solution but I have found a work around. If you have TextExpander or Alfred this will work much faster.
I was able to use the 'pmset -g log' terminal command to find out that mDNSResponder was the reason my MBP wouldn't fall alseep. So it has something to do with Bonjour.
I then found a pair of command codes to shut off and turn on Bonjour. After using them, my MBP goes to sleep without issue.
Turn Off Bonjour: sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
Turn On Bonjour: sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
You'll notice that when you turn off Bonjour that you won't be able to use the Internet. That is the only down side to this work-around.
Using Textexpander you can use 'ssleep' and 'wwake' for the two command codes and alfred can give you quick access to the terminal.
I hope that helps somewhat.

When I touch my iPad screen to execute an app, the screen goes dark then the app icon reappears. The app does not execute.

Try a Reset...
Press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears. Release the Buttons.

MacBook Air Boots to OS, then screen goes dark.

I have recently been working on an older style (A1304) MacBook Air with the 128GB SSD. I've been working on Mac's for years, and have worked on hundreds, but this is the first time I've ever come across this particular issue.
Liquid damaged MacBook Air. Keyboard and Trackpad mainly took the brunt of the spill. Popped off the keys, cleaned it all up. Button for the trackpad no longer works, but everything else does. Entire computer was disassembled, no other liquid was found.
MacBook Air boots up normally, and I was using it for a few hours to make sure everything was working fine. Left it to charge. Came back two hours later, and the screen was dark (but the image was still visible, as if the backlight was not on). Could see the mouse pointer moving, but backlight won't come back on. Turned off computer, turned it back on. Backlight works just fine, and it boots to the OS. Within 10 seconds of booting to OS, the screen goes dark (screen goes completely black with no image). Couple seconds later, light on the front starts to "breathe" indicating it's sleeping. Wake it back up, and image appears on the screen, but no backlight. Then it "goes to sleep" again.
Boot computer to a Flash Drive with Snow Leopard Installer and once the blue screen comes on as if the installer is just about to pop up, it "goes to sleep" immediaetly. Though, the backlight and computer will stay on in the Apple Hardware Test for as long as I want. (ran it several times, "no trouble found". Also reset the PRAM, nothing helps.
I was wondering if anyone has ever come across this. Completely baffled on whether it's a software or hardware (or combination of the both) issue I'm having.

The keyboard and trackpad reside on top of the motherboard and all the components of the computer. The keyboard and trackpad are not liquid proof. It is VERY likely that the liquid made its way to the motherboard and has affected those components. If EVER there is liquid spilled on a computer, the last thing you want to do is A. Turn it on to make sure it is working.. and B. Plug it in and charge it. Do the EXACT opposite. Unplug and turn off all power, and, if possible, remove the battery from it. The liquid itself doesnt do the damage...the damage is done when the liquid comes in contact with the circuits and shorts out the contacts and components. You could try to connect to an external monitor, if you have the means to do so, to see if it makes a difference, but it probably will not. I seems that the motherboard is not functioning correctly.

Edge 540 model : when I connect/disconnect AC power cord, screen goes dark

For the past few days, everytime I connect the power cord, the screen goes dark for a second. The same thing happens when I disconnect the power cord. Can someone help me find out what is wrong with it? Is it a hardware issue or is it just a momentary glitch (It just started happening yesterday)?
My laptop is brand new so I can use the warranty if i have to.
OS: Win 8
Thank you.

this is a normal behaviour it happens all the time. It is your refresh rate changing between different power setting. Set the screen refresh rate at 60 hz for both battery and with ac adapter connected this should prevent the momentary blanking of the lcd.

700P Sprint Update 1.10 - Screen goes dark after sync

I updated my Sprint 700P yesterday to V1.10 Palm software. All seemed to go well with the update, until I tried to restore my data with a HotSync.
The sync seems to go normally, but at the end, it says a "reset is necessary"...after the reset, the screen goes dark right after the Palm logo appears. The phone seems to be still working.....just no visible screen.
I spent hours on this yesterday....now have no working phone.....very frustrated.

Post relates to: Treo 700p (Sprint)

Yes
i just replaced my 700p due to this issue and return home to find that nothing has been resolved.
It turns out that the update is rather seriously flawed. There is no way to revert the update so, Verizon (after checking with Palm) replaced my Treo and suggested that I not run the update again.
Now the sync issue that you describe.
There appears to be files associated with your treo on the Palm software on your desktop that are set for installation. This was due to the update i believe. These files: specifically those associated with AudibleAir.pdb are creating havoc during the sync.
The Work-around that Palm suggested to me which appears to work (on the new phone with the original ROM) is as follows:
1) Hard Reset the Treo
2) Re-sync the treo
!> When it asks you to choose the correct id, DO NOT DO SO!!!
3) Create a new ID for the treo and continue the sync.
This way these bad files are no longer set for installation because you are not using the same account as when you ran the update utility.
I would be interested to know if this works with a Treo 700p with the new ROMs installed.
My method requires the old ROMS and Palm in its infinite wisdom has not created any means of rolling back to the old ones. Thus a catastrophic update.

6288 - screen goes dark after 15 seconds

Hi
Have just purchased a 6288. Screen goes dark after 10 - 15 seconds if you don't touch the keypad - very annoying if reading a message. Have turned Power saver and sleep mode off, but screen still goes dark. Does anyone know how to stop it from doing this?
Thanks

Yes it is quite annoying. The screen saver time out does little to remedy this. A way around it that I use is to reassign the navikeys. you can dictate what each button does :go to menu > settings > my shortcuts > navigation key. my up goes to contacts, left goes to new message, right goes to music player and down does nothing. so every time the screen goes black, I just hit the down key to turn it back on.

Curve screen goes dark while navigating

While using Verizon Navigator, Curve 8330 screen goes dark unless I continue to hit the rollerball every few seconds. The security option allows for a 2-minute window but, at times, I will need hours of screen light. How do I correct this?

Computer screen goes dark (stops)after latest update.

After my latest update,computer crashes,screen goes dark,using wireless mouse;difficult to restart.
Is it 6.3 or the mouse?

First, Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk.
You could have some directory corruption. Let us know what errors Disk Utility reports and if DU was able to repair them. Disk Utility's Disk Repair is not perfect and may not find or repair all directory issues. A stronger utility may be required to finish the job.
After that Repair Permissions.
No need to report Permissions errors....we all get them.
Then, download the 10.6.3 Combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
You can install it right over what you already have.

When I power up my mac, I see the white screen and the apple icon. After a few seconds of powering up the screen goes dark. Yet I still can the mouse arrow but nothing else.

When I power up my Imac, I see the white screen and the apple icon. After a few seconds the screen goes dark. I am able to still see the mouse arrow as I move it around. But nothing else. What is the problem and how do I recover?

Try this from another user:
1. Shut the computer down by holding the power button for 10 seconds
2. Restart the computer and press shift at the same time until you see the progress bar start moving
3. Once you reach the point where your screen goes dark and you see the cursor, type the first letter of the username for your computer, then hit Enter, then type your password, then hit Enter.
4. After a moment, you should see the spinning beach ball
5. Your screen should then move on to something along the lines of "Completing OSX Installation" (I can't remember the exact wording). Let it finish. After that it should go to your normal desktop and the issue should be fixed. (If your screen goes pitch black during this process, hit the space bar. I thought it wasn't working, but the screen was just sleeping).

IPhone 3GS screen goes dark...no apparent fix for it

My iPhone 3GS has started having a problem where the screen goes dark. The phone is still active and if you have the right light and strain real hard you can barely see the icons. I have tried everything I know to fix this but nothing works. One thing that did work for about a day was a Reset All Settings, from the General Settings menu. Previous to doing that, I have tried: 1) turn it on and off, 2)hard reset, 3)restore from iTunes. None of these worked for more than a few minutes. I did restore firwmare from the computer but I have not tried putting the iPhone into DFU mode...is there a difference?
Any ideas appreciated.

All iPhones require a SIM for updating/activating.
The SIM does not need to be active, simply insert a SIM card and activate the device. Borrow a SIM from a friend if necessary.

Screen goes dark too quickly while on call

Hi- I am just learning to use my new iphone 4, already did software update. When i am on a call, the screen goes dark within a few seconds so that i cant easily get back to the keyboard, the screen that allows me to go on speakerphone etc. Is this normal? I adjusted the auto-lock in settings but i couldnt find any adjustment for the screen going to sleep while on the phone. Also, is there any way to adjust the number of rings before the call goes to voicemail? Thanks.

Screen goes dark intermittently

Formerly very occasionally, more frequently of late, I will be working away om my laptop and the screen goes dark. My workaround is to close the lid to put it into sleep mode and then resume Windows.
My screensaver is set up to go dark in two stages over several minutes, first dim, then dark, so I don't think it is related to that, as when this problem occurs the screen goes black instantly.
Later: the last time I just let it sit and it went into hobernation on its own. When I hit the power button Windows came back up. Maybe it's a power issue; I am going to check the diagnostics.

The battery is fine -- 98% Charged. The more I look into this the more I think something is prompting the latop to go into Hibernation mode without me asking. But what?

Screen goes dark while typing password.

Since recent Samsung upgrade, screen goes dark so quickly that it's difficult to get the password entered in time to unlock phone. Any ideas?
