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?

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.

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.

My new iPhone 5 just blacked out and won't come on. Does anyone know if I will have an issue with Verizon getting a new phone?

MMy new iPhone 5 just blacked out and won't come on. Does anyone know if I will have an issue getting a new phone from Verizon.? I can't even call because I don't have a phone!

Ebony,
Let's see if we can't get this phone working for you! What exactly is happening with the device? Is the screen just out and you can hear that it will still ring, or is the phone completely dead? Please elaborate more on what you are experiencing.

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

New MBP mini Display Port out to TV (HDMI) not working

Sorry, I just realized I put this in the Original Folder not the Late 2008 folder.
I bought a new MBP 2.4 GHz, 4 GBs RAM machine in January of this year, 2009. Model Identifier 5,1. I wanted to connect it to my TV's HDMI port. Only interested in getting video to TV since I run sound through a sound system. I have been using my MacBook Air's DVI adapter to a DVi - HDMI cable. I have a Sony Bravia 40 HD tv. Video works just fine from my MBAir, can change resolutions to anything and video works perfectly (audio has a little problem though - high frequency hum out of the MBAir's audio port). That's why I want to change to my MB Pro - audio from the New MBP is good.
With my new MBP, using it's Mini out- DVi connector and using the Same Video (HDMI) cable that I used with my MBAir - it doesn't work. The Display Preference does not detect the TV ever. I just get a black screen on the TV. Not even a flash on the TV like it's trying to connect - nothing.
I can pull the cable out of my MBP 2.4 and swap the DVi connector to the MBAir's cable and put it in the MBAir and it works just fine. Swap it back to the new MBP and nothing.
I have tried two different MBP Mini DVI out connectors, thinking one was bad. I even took the connector I use with the MBAir with me to the Apple Store to have them match the connectors, so I would be assured that I got the correct one. Oh by the way, my MBAir is the original one, not the newest one.
I have read a lot of links on the website where people are having trouble with Monitors using the new MBP Mini DVI video out but could not find any thread that matched my TV problem.
Any suggestions or explanations would be greatly appreciated.
Thanks,
Jim

Hi Jim,
Just to clarify, you state that you have a MacBookPro5,1, which is the late 2008 model. The video output on that model is a mini-DisplayPort, not a mini-DVI (like the pre-unibody MacBooks) or a micro-DVI (like your 1st gen MBA). DisplayPort is a different type of port. (Note - I requested an edit of the title of your post to clarify that).
When you connect the TV, in what sequence are you connecting? The 'proper' sequence is to connect the DVI-HDMI cable to the mini-DisplayPort to DVI adapter, have the HDMI end connected to the TV, have the TV set to Line-In, looking for a signal, then connect to the MBP last.
What happens when you connect it like that? Have you tried System Preferences > Displays > Detect Displays?

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?????

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?

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.

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.

New Gateway desktop monitor blacks out, but power's on...

Anyone have a clue why a brand new monitor would go black shortly after it's turned on? We're on the illiterate side of computer stuff, so any tips would be helpful. Waiting on Geek Squad to call back...and waiting...

Its defective, thats for sure. Its time to take it back to the store and exchange it for another one.

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.

Keyboard shortcut for adjusting exposure causes image to black out for a short time.

Hi everyone,
I have always used the mouse and slider for adjust things in the develop module. I know started using the keyboard shortcuts for faster editing as sugested by everyone and I do like it. My problem is when i adjust any slider with the + or - keys my picture completely blacks out for a moment then comes back with the adjustment made. This is frustrating and completely defeats the purpose of using keyboard shortcuts for speed.
The only changes I made is I upgraded from a very old dell dimensions computer to a new alienware X51 computer. I am using lightroom 4.4 64bit and a HDMI connection to my monitor.
Any help would be greatly appreciated.
Thanks for your time.

Cj,
My guess that there is some other hot keys attached to '+' & '-' keys on your keyboard.
Try to put your system in clean boot and try to launch Lightroom and see if the issue still occurs.
If you dont get the issue any more go ahead and isolate the app which is causing issue by following divide and rule method on the apps.
