Display Black out

My BRAND NEW MacBook´s display went completly dark... after 1 week´s use. There is a hint of light on the right top corner but that is all. WHATS GOING ON? Has this happened to anybody else? I´m very dissapointed in this computer.

Had a similar issue, just got it resolved. Here are the steps to take:
1.Unplug the AC power cable from the laptop.
2.Turn it upside down and remove the battery using a coin to turn the groove to the open lock picture.
3.Take out the battery.
4.With the battery out, press and hold the power button for five seconds (One mississippi, two mississippi....five missi....you get the point).
5.Release the power button
4.Re-insert the battery.
5.Lock the battery in place.
6.Power up the laptop and continue to have fun.
P.S. Don't be disappointed, this is still the best thing in computing..what's the alternative?

27 inch thunderbolt display blacks out after Thunderbolt Firmware Update 1.2

Bought 2 new 27 inch TB displays for two different machines and after a couple of days the Thunderbolt Firmware Update 1.2 appears on my Mac Pro with one of the displays installed. So I install the firmware update. Now my display blacks out periodically and I keep getting Graphic Display Errors with a request to sent the errors to Apple. Running a 32 GB Mac Pro (late 2013 circular style) I have three monitors connected (two 20 inch cinema displays and the new 27 inch display). This machine is supposed to be able to handle three 4k monitors or 6 standard TB displays. I've seen the posts about the blacking out with this monitor but I didn't have any problems before the firmware update and now I've got them pretty regularly. I had the blacking out problem on an earlier monitor and took one of the monitors back and Apple gave me another one and this is the replacement. Same problem, but this one only started after the update. I'm hoping someone from Apple reads these messages and can let me know what's up.
BTW, I also have an older 27 inch Apple monitor that ran perfectly on this machine so I'm disappointed that I spent all this money and now get the blacking out issue.

I have my Thunderbolt display connected to my MacBook Pro and have been experiencing the same issue, getting worse over time. The folks at my local Apple store did not know what to do about it. So, I looked around and tried different thing.
The one thing that seems to be working is to System Preferences > Build-in Display > uncheck “Automatically adjust brightness.”
I hope this helps.

Display blacks out

so on my ibook g4 mid way through using it the screen blacks out (there is a very faint glow) this is happening more regularly now and atm as a temporary fix i just close the lip and open it.
iv looked through some forums and it seems like a problem that i cant fix myself...
but i was wondering can i just connect the laptop to an old display i have? or that display black out as well.
any help would be great, thanks.

Welcome to Apple Discussions!
When the display blacks out, can you shine a flashlight through the back and still see your desktop? If so, you likely have a problem with the back light or inverter or possibly a cable, which will affect the built in display. Since you can see your display at times, I imagine that the graphics chip itself is still working OK.
Is your old display an external display? If so, it should work.
Good luck!

DISPLAY Blacks out sometimes

Most of the time when I sit back down at the computer desk my display black out for a second. The light turns of, but it comes right back on. Someties it does it several times before it stops. I know thta there is alot of static in my apartment. Does anybody know anything about this? If so, is there anything I can do to prevent this?. It is pretty annoying. Any help would be appreciated.
Oh yea, the display is a Starlogic

I have a Mac Pro, and a Mac Mini. I have owned tha Mac Mini for about two years. I have found the same issue with my mac mini. I do believe that it is normal, and it has something to do with the shared memory. I ran it for over a year as my main Mac, and I experienced the very same thing. I don't think it is anything to worry about, unless it happens over and over. My Mac Pro does it form time to time, although very very rare. It also could have something to do with the display, analog vs digital etc. I believe the digital signal experiences very short interrupts every so often, and that in my experience is normal

HT5219 Apple thunderbolt display blacks out and blinks

Hi,
I have a macbook pro (2.5GHz Intel core i7, 16GB RAM and 10.8.5) for which I use Apple Thunderbolt display as my extended monitor and almost everyday after connecting my external monitor for 3 or 4 hours, Apple thunderbolt display blacks out and starts blinking or displaying weird colors on every blink.
To stop it from doing that, I have to disconnect and reconnect my thunderbolt display.
Is this is universal problem or something wrong with my macbook pro ?

I've got two 27" Thunderbolt displays hooked up to my Mac Pro. Both displays blank out irregularly multiple times per hour.
I've exchanged one of the displays for a brand new display and the problem continues.
I've updated both displays using the firmware update a few months back and the problem continues.
I'm using separate Thunderbolt cables rather than the built-in cables and the problem continues.
Bullocks.

External Display Blacks Out

I have MacBook Pro 13" (early 2011) hooked up to an external display. With Snow Leopard this setu worked fine. But after upgrading to Lion the external screen constantly blacks out. I've seen some suggestions saying that it might be the adapter but, as I said, this setup worked fine in Snow Leopard so I find it unlikely to be an adapter issue.
Does anyone have any suggestions on how to fix this problem? It's extremely annoying.

This has been fixed in one of the latest OS updates.

A new 23" studio display blacks out from time to time

Just got this great new display. Once a day maybe, the screen goes black for about one second, then pops back up.
What could be causing this?
G5, single processor Mac OS X (10.4.7)

One thing to consider, maybe you accidentally move the mouse into the sceensaver hotspot and then once it starts to black out, then you move the mouse to turn off the screen saver and it seems like it blacks out?

Display blacked out

All of a sudden, my MacOS display has blacked out (background) and all icons and pix look like negatives. I've checked all Preference settings and can't find anything wrong. Anyone have thoughts? THANKS!

Try control-option-command-8 and see if this is it.

MBP C2D 15" display blacks out!

My week old MBP C2D 15" blacks out on me. I find that it happens when applying light pressure on the back side, at a surface square underneath F1 - F5 - F - Caps Lock. Light pressure makes it flicker, a little harder results in complete black out. Obviously a production fault and I will of course take it in when I have time... this is my work tool so no way I can just leave it in for days. But that is another issue. Maybe someone else experience the same black out? My build is 8N1037

Hello
Did you find out the reason? The same message shows up in the system.log of my iMac Core Duo after the Mac OS X 10.4.9 Update, but the iMac works fine.
Cleaning all caches, repair user rights, PRAM and SMC Reset didnt help. Also no luck with Preferential Treatment tool to check for corrupted preference files, it didnt find corrupted plist files.

PB G4 1.5 Display Blacks Out. Any ideas?

So I have a 1.5 12" PB. I love it. It's a great little machine. Randomly my screen decides that it would be a great idea to go black, no backlight on. I can still see faint images on the screen and everything is working, just no backlight. I close the lid, let the machine go to sleep and then the screen comes back on, well for a bit, usually another 2 or 3 minutes. If I plug it in then it's fine, no issues. I have been able to isolate the incident to ONLY when the PB is disconnected from the power supply. I have ran AHT, and TechTools and everyting is A-OK by that standard. I have adjusted the brightness in system prefs, I have adjusted the settings so the machine doesn't go to sleep, I replaced the reed switch, danced around in a circle while chanting... You know the usual. So, I am stuck with a few ideas, unless you have a fix for me, in which I would be forever grateful. Could this possibly be the inverter? (hope not!).
Thanks, any help is GREATLY APPRECIATED!

Ok, so a new revelation. I switched out the battery and viola, no blacking out as of yet. So now I am really stumped..... I have reset the PMU previously, and it still wasn't working. So maybe it's a bad battery?????

T400 display blacked out suddenly

Screen on T400 laptop suddently went black. Adjustment of brightness function keys does not improve.
Please advise
jrevco(at)gmail.com

More information is certainly needed for people to be able to really help. However I will note that I've had my T400 screen "black out" three times in the last couple of weeks. All three times it reset after no more than 10 or 15 seconds or so with a "video driver stopped responding, driver restarted" error (I didn't write down the precise wording -- that's pretty close though). I also see a quick popup mentioning a "amdkmdap" error right before I see the video driver restarted message.
A couple days after I got my T400, I set the BIOS to use discrete graphics only and had no problems whatsoever -- a couple weeks later I changed back to switchable graphics to see if it would give any problems. Since it apparently is giving problems (and since the most recent Lenovo switchable graphics drivers updates will not install after trying several times), I've now gone back to discrete graphics only - so far no problems at all.

Display blacks out when panel is extended

My pbg4 screen turns black (no light) when the display panel is open about 80 degrees or further. Just started...like a short in a wire. Sound familiar? Any help on downloading instructions to remove display panel will be appreciated.

Start with the wiring harness coming out of the left hand side, because you probably dont need to disassemble the LCD to find a frayed or pinched wire. Since it happens when you move the hinge, I'm pretty sure thats your problem-- (intermittent blackness without motion could as easily be the bulb or the inverter).
The harness responsible for this has four wires: orange brown, red, yellow.
Where mine got pinched was underneath a black plastic block with a single screw, that pins it down to the lower chassis near my hinge.
I fixed my wire by snipping it cleanly, slipping on a tiny piece of heatshrink tubing, soldering it, and sealing it with the heatshrink tubing.
I have not come up with a more durable solution for opening and closing with the lid yet -- but hopefully that'll give you an idea of where to start.
I got this idea from another post, but it didnt go into much more detail about which wire he was talking about.

ITunes Visualizer on External Display Blacks Out Main Display

Is it possible to have the iTunes Visualizer full screen on an external display while keeping the main display active?
In other words, I'd like to have my 2nd monitor display the iTunes Visualizer in full screen while I do work on my main screen. Every time I try this it forces the main screen to go black.
Does anyone have a solution, or is this just the limitations of iTunes and/or the Mac?
(By the way, the closest I've come is to put the iTunes window on the 2nd display, start the visualizer, and make its window as large as it will go. But, you still see the top of the iTunes chrome above and below the visualizer.)

I realise this is an old post, but have not yet seen an explanation of how I have solved this problem.
Its not a complete solution as it only works if you want to use iTunes, and does require an iPad or an iPhone.
First configure the Apple remote App on your iPhone, or iPad, or both iPad is best, but iPhone works almost as well.
Check that you can control the music from your i'Device'
Drag the iTunes window onto the external screen/projector. I am assuming external monitor with a different screen geometry to main screen, but if you can handle some gaps, you can mirror displays just as well.
Turn on the Visualiser - and put it into full screen.
If you can't see the external screen the following short cuts are useful.
⌘T - turn on Visualizer
^⌘F - turn on Full Screen
Your main screen will blank out, but you will still have full control of your music from the Remote App.
Very cool if you are having a party, and want the visualiser on the large LCD TV, or on a projector.

27" LED Cinema Display Blacking out for no apparent reason.

I have looked on line for a clue to whats going on. It seems to be happening to many people and there seem to be no easy fix. This is a monitor purchased less than 18 months ago. I don't currently have the money to dish out another $1000. Is this the life expectancy of this monitor?

My 27 inch MC007LL/A A1316 LED Display 12,000 JP Y , from HARDOFF ! a recycle shop there was no plug so the guy gave me a square Power Mac Plug so I got them to cut it by 30% ,then a week after I found a a plug cord ,I reckon it was the missing plug and I reckon that the owner gave up on it ,because of this problem ,last month suddenly power went out ,no power in the recharger , no broken parts,it had been on sleep since Sep 2014 and even a power outage last month when I had to flip up the stopper,it still worked , it is a power problem, because I waited 30 minutes and plugged it in and it works again .Why ? I spent hours reading all these posts on power failures ,The power unit makes heat and even a Fan can not get rid of it so ,in order that the power unit does not burn out it will shut down simple as that. Do you think that such a Power unit will keep on going with power and keep cool even a Fan will get hot from going full speed to cool something so shut down cool off until it is cool and then return to the Factory settings. Heat is the biggest killer of Electronic parts if they get clogged up with micro dust they cause mini shorts and water vapour ,condensation,humidity,if you notice there are grills for letting out heat but also let in dust from garments that stick to static parts and water from condensation that also cause shorts on the motherboard and defects in parts ,remember the G5 Taiwan caps that Apple managed to hide? I have taken apart 2 x 20 inch G5 s junk and found dust caked on them
