Screen flickers black

We purchased an IMac late 2010. Love the reduction in popups from our PC. Just recently noticed the screen "blanking out" during light use. Very quick reaction, no loss of power. Any advice?

I've had the same problem where my MacBook screen flickers. You need to bring it to the Genius Bar at the Apple Store and have the inverter replaced. You have to check it in though for them to do the repair, so you will be without your MacBook for a few days.

Recording of screen flickers black?

I'm trying to just record videos of me playing Starcraft 2, but whenever I start FMLE my mouse flickers not just when I open up Starcraft but when it records my desktop too, and when I try to watch the playback of the video my screen flickers black and back on. Are there any settings that I might need to change?
Pentium Dual-Core 2.5ghz
4gigs of ram
Nvidia geforce 9800 GT

If showing mouse is not important, you can disable the "show mouse", "show clicks" and "track mouse" options of VH screen capture.
And what is the CPU usage while encoding? Is it too high?
You can also use other sceen capture softwares such as Uscreencapture.

HP Monitor L1710 -- power light flashes green when I turn on PC, screen flickers black w/ no image

Hello,
Last night I turned off my PC w/ a HP Monitor L1710, which I did not turn off. When I turned on my PC this morning the screen does not "turn on" -- the green light next to the power button flashes on and off, and the screen flickers between shades of black, like it's trying to turn of. This PC usually is not turned off at night (this is a work PC, and I just started to working at this desk (almost) never turned the PC off at night, so I wonder if it has something to do with that. I've turned the PC on and off multiple times, unplugged the power cable (for the monitor) and cable that runs from the monitor to the PC. I believe the PC is on (cd drive opens and closes, recognizes my phone when I plug it in to charge), so I don't think that is the problem.
I see a lot online that it may be stuck in power saving mode.
Any thoughts? Any help or ideas would be greatly appreciated

Hello @tom_degennaro,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I understand that your monitor is not coming on when you turn on your PC. I am setting out some steps for you to try for you to try below:
Step 1. Unplug the power cord from the monitor and the wall outlet
Step 2. Hold the power button down for one minute
Step 3. Plug the power cord back into the monitor and then the wall outlet (not a powerbar or surge protector)
Step 4. Press the Menu button on the front of the monitor
Step 5. Navigate to the Factory Reset option and select it.
If the issue still persists after the above steps try the monitor on another computer. If the monitor still does not work at that point then, it appears to be a physical issue and I think it would be best if you contact HP Technical Support for repair options.
If however the monitor works on another computer you have an issue with the computer it was originally on. If the computer is an HP computer I would be happy to assist you with, but first I would encourage you to post your product number for the computer. I am linking an HP Support document below that will show you how to find your product number. As well, if you could indicate which operating system you are using. And whether your operating system is 32-bit or 64-bit as with this and the product number I can provide you with accurate information.
How Do I Find My Model Number or Product Number?
Which Windows operating system am I running?
Is the Windows Version on My Computer 32-bit or 64-bit?
Please re-post with the requested information and I would be happy to provide you with assistance. Thank you for posting on the HP Forums. Have a great day!

Photoshop CS6: Screen flickers black when using brush tool on MBP 2013

I'm experiencing a flickering black box whenever using large brush sizes on Photoshop CS6 using a Macbook Pro (16GB RAM, 2.8 GHz i7, Intel Iris, Late 2013 13") similar to what is shown on: black flickering boxes on Vimeo. The issue stops if you: Preferences -> Performance -> Uncheck "Use Graphics Processor" and restart the program or backrev to CS6 13.0.0 (or anything before 13.0.4).
I've attempted uninstalling/reinstalling CS6, resetting NVRAM and SMC, and verified the system is all up-to-date. When booting in Safe Mode the issue is also resolved (as it appears Graphics Processor is disabled). There appears to have been a similar issue on the 2013 Macbook Air that Apple released a fix for (MacBook Air (Mid 2013) Software Update 1.0) but I do not see anything regarding the Macbook Pro line. Anyone experience/resolve this issue?
I've contacted Apple Care multiple times and they say it is an Adobe issue. And Adobe is insisting is a CPU/GPU driver issue just like the Macbook Air issue Apple already fixed.

You may be able to get a display driver update from the laptop manufacturer.
Unfortunately, if none of the workarounds is circumventing the problem for you, and there are no display driver updates that solve the problem, you may want to escalate it to the laptop maker. They in turn can push through a new display driver update. They should take responsibility for making your system work with modern, professional software.

MacBook (Early 2009) Screen Flickering, Black-out

So to describe the problem in short, my MacBook is having issues with the screen in random instances. It only seems to happen when I am running some high CPU performance requiring software/games. The screen will turn black about 70% from the bottom up, and the remainder of what is visible will be blinking. Is anyone else expierencing this issue?
No I have not dropped the machine, I barely move it because it is not my primary computer.
I will post below with some specs so you can take a look. I will note that I do not use this hard drive for much, I have never filled it with music because I use iTunes homeshare for that, it is mostly used for student stuff like Microsoft Office.
I recently discovered the issue when I was video chatting with some friends on Skype, as well as running a flash game (on Safari) and suddenly the screen went out. the only way I was able to bring it back was by CMD + Q to quit Safari, which I knew was running and selected. I currently an only using 26GB of my 250GB hard drive, and that is with the Sims 3 game installed, which also will not display on the screen correctly.
As far as troubleshooting, I have reset the PRAM and NVRAM, as well as the SMC. I followed two links on the Apple Support page to find out how to do that. Any further suggestions? My MacBook is unfortunately not under warranty any more so I am not sure if the Apple store Genius Bar will even help me.

Sounds a lot like an overheating issue. My son used to run his Mac in his lap with a blanket in his lap. The blanket was not a good thing to be putting the Mac on top of as it trapped all the heat it was making. When he would play an intensive game, something like what you describe would happen until things cooled off.

While I am in a selective mode in cs6 my screen flickers black. How do i fix this?

This is extremely frustrating while I try to work. It makes my editing time so much longer. Does anyone know how to fix this?

"in a selective mode in cs6" ??? 32 bit or 64 bit standard or entended OS config

- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.
Apple Retail Store - Genius Bar
Apple will exchange your iPod for a refurbished one for $199 for 64 GB 4G, $99 for the other 4Gs, $99 for the 16 GB 5G and $149 for the other 5Gs. They do not fix yours.

Desktop restart shows flickering black/white screen, then black. Could not restart. Anyone else with this issue?

Have the PRAM battery looked at. It may be all that is needed.

My screen flickers/fades to black

Screen flickers, sometimes fades to black screen completely, have to hold down power/home button at same time for a few seconds until Apple icon shows back up and sometime it doesn't. Any solutions to this??

First I would buy the correct charger from your local Apple Store or Apple reseller. If that doesn't solve the problem and if the machine is covered by warranty or AppleCare (yes Apple warranties are transferable) make an appointment at your local Apple Store and take it in.
Good luck,

Black Screen Flickering in Photoshop

Hello everyone,
To my dismay I just noticed a black flickering on my screen when I was using Photoshop CC. It was when I was zoomed in on the image but I noticed that it streched the who screen length. I'm hoping it is just a photoshop issue and not some sort of hardware issue. I have the application frame turned off in photoshop so it may be possible that is why the flickering exceeded the image frame (technically the program is edge to edge on the screen if the frame is off).
I admit that I am posting this before doing more tests but it's really unnerving to see it on a new Macbook Air. For reference, I have a core i7 2013 Macbook Air with 8GB of ram.
I'm going to try to simulate it in a minute or so. This time I will adjust the frame.
I appreciate any input if you have had this issue before or are currently experiencing it.

Join the party:
My screen flickers in Photoshop on my 2013 Macbook Air.

IPhone 5 screen is flickering randomly, the phone freezes and the screen turns black.

I bought an iPhone 5 in New York last December. Now I live in Bogotá, Colombia and I can't find an authorized service center because they said that only if I bought it from a local carrier they attend the warranty.
My iPhone 5 screen is flickering randomly, the phone freezes and the screen turns black… The only way to make it work is to reboot with Home and Lock buttons pressed at the same time. But in the process most of the times it flickers again, and again, and again. I couldn't find a reason to identify what could be causing the issue. Also sometimes when it freezes, some group applications get ungrouped, causing a big mess.
I already tried to restore the phone, remove the SIM, delete all applications with no luck.
Any sugestion? Thanks!

Was this phone ever jalbroken?
If restoring as new, without using a backup, didn't help, there is certainly a hardware problem that only replacement can fix. Your warranty is void unless you return to the USA. Short of that, finding a local independent iPhone repair center would be your only option

Why is my 2007 HP V17 monitor screen flickering and going black?

I have an old 2007 HP V17 monitor attached with a VGA cable to an early 2008 Macbook running on OS 10.6.8 software via a DVI- mini connector (this is also my desktop computer).
About 6 months ago, the HP display started going white and sometimes gray for a few seconds before the image would return, and a couple of times I had to unplug it and restart the Macbook before it came back. I followed Apple's instructions for testing whether the problem was in the computer (= resetting the system by resetting the Mac's parameter RAM and SMC), but the computer tested okay. I then purchased a new VGA cable and DVI-mini connector, but the problem persisted.
Today the HP screen suddenly went black (first time going black) and stayed black. The power button stayed lit and if I pressed the Volume or Auto buttons, the "Volume" etc. message boxes did appear, so the device's backlight is apparently working and not burnt out (unless the backlight has nothing to do with the message boxes showing up, which for all I know may be the case). However, the Desktop showed up only on the Macbook.
I checked all the connections, removed the DVI connector and plugged it back into the Macbook several times, but the HP screen stayed black, so I removed the DVI connector in order to type this message on the Macbook. Then, as I was writing this, I decided to plug it back into the Macbook one more time--and sure enough, the display is back!
I love this monitor, which is the perfect size and ergonomic height for my setup, so I'd hate to have to replace it. Can anyone tell me
Given the information above, what's the probable reason for the flickering and going to black? If it's the computer, what could it be? Can I solve this problem myself? (See above; I couldn't find any other ways to test the computer in the Apple articles database.)
If not, could a monitor this old be repaired?
If so, how much would repairing it cost, since buying a new monitor that I probably wouldn't like as much would cost upwards of $300?
Thanks so much for any advice out there!

I understand that your HP V17 Monitor has gone black and is not displaying anything. I am providing you with some steps for you to try below:
Step 1. Unplug the power cord from the back of the monitor and the wall
Step 2. Hold the power button down for at least one minute
Step 3. Plug the power cord back into the monitor and then into the wall outlet (not a power bar or surge protector)
Step 4. Press the Menu button on the monitor
Step 5. Navigate to the Factory Reset option and select it
If the issue persists after this you can try the monitor on another computer to see if it continues. If it does it appears to be a physical issue and I think it would be best if you contact HP Technical Support for repair options.

MacOS X 10.7.5 screen flickers in black and freezes for 2 minutes

Recently noticed a problem - in Finder, column view (this is important) if I select a pdf file (noticed only for pdf) screen flickers quickly several times in black color and the whole system freezes (except mouse cursor) for 2 minutes (I've measured with timer). After that, everything goes normally, file preview is displayed on the right side in Finder window as it is expected to be and file can be normally opened with Preview app.
Can anyone suggest on this? Where should I start looking to for more information (any logs)?
I have MBP late 2008 aluminium unibody with 4GB RAM, 2.4Ghz Core 2 Duo.

When I try to close my screen it flickers black

When I put my computer to sleep I put the screen down instead of going up to the apple in the corner and selecting sleep. It is now flickering black as I am putting the screen down. I do not know why. Even when I just put it half mast it flickers.

I too had a similar problem, only over the course of one evening, the screen eventually went blank. I brought it to the Genius Bar and they replaced the LVDS (I think) cable, which I believe connects the display to the rest of the computer. No charge if under warranty, otherwise, the invoice showed it would have cost $152.00. Take it in if you can and good luck!
