Screen flickering to black

My ATV is flickering intermittently. It flickers black and then back again, literally taking only seconds, but then keeps happening on and on, making everything unwatchable.
This is NOT the negative image problem, however it is a Sony Bravia KDL-W4000.
Anybody else having this problem, suggest a fix?

Its hard to tell, but it seems that turning the playstation on and switching HDMI slots initiates the problem when I return to the apple tv.
However, try this, turn on the apple tv, make sure no other HDMI devices are on, switch to another inactive hdmi input, and switch back. Its a bit early to tell, but the problem doesn't seem to present in this order.....maybe forcing some sort of HDMI handshake when switching channels and then back again?

My iPad is suddenly not loading any apps. When I click on an app, the screen flickers to black and then back to normal, but will not load the app. This is ALL the apps, not just one. Have tried rebooting, to no avail.

Was a Restore one of the things tried.? [Attach the iPad to your computer and in iTunes click on your device. On the Summary page click on Restore and go through the process. Be sure to click YES to Restore from a previous backup.]

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.

Macbook pro screen flickering brightness/black screen?

on saturday night I was using my MacBook pro and drinking water when my friend made me laugh so I accidentally spit like 5 drops of water onto my macbook screen. the drops leaking down into the base, not exactly the keyboard but just right under the screen where it would drip down. a instantly got a towel and dried it off but the macbooks screen statted flickering off and on. then it went permanently black but it seemed like it was still on. I tried to hold down the power button and it would make all the on and off noises just the screen wouldn't work. it would maybe flash for a second but then just go dark. I made the mistake of not turning it completely off when it first happened because I didn't know what to do but after maybe 10 minutes I turned it off and opened it up and kept it upside down the whole night to let the water come out if there was any. the next day around 12pm I turned it on and everything was working completely fine. no problems or signs that eer spit the water. then the next day (Monday) half way thru the day I was watching Netflix and I noticed every 5 minutes or so the screen would dim no matter what brightness I had it on and after a couple seconds it would go back to regular brightness. after like an hour it started doing that more frequently and it gave a black screen until I moved the cursor. I paniced and shut it off for the rest of day thinking it would be better the next day. well the next day (today) I turned it on and it was even worse. it's almost like the screen is having spaz attacks every 2 minutes. it'll go dim or bright randomly and then go black until I move the cursor and when it gowa dim there's these weird bright lights things coming from the bottom of the screen. but other then that the macbook works completely fine. iit's still usable, and the screen spasms are annoying but I could live with them. but first I want to make sure it's not going to get worse and worse everyday and just permantly die soon. im only 15 and Ive been dreading telling my parents what happened but if i have to replace something I have to tell them. I've tried researching what I have to replace but no one has my exact symptoms. I think I'd either have to replace the Lcd (whatever that is??) or the inverter. someone please help, thank you!!

G580 screen flickering to black and heavy pixelation

So I have a G580 laptop that's in good condition and recently updated.
About a week and a half ago I noticed that my screen would flicker and become heavily pixelated with color and flicker black (I included a picture). Usually it would go back to normal, but occasionaly it would continue to flicker and pixelate. Moving the screen does't affect the problem, rebooting sometimes helps, and I've done hardware scans that came back clean. (Programs work like nothing is wrong, its just the screen) Nothing in my laptop seems to be brocken so I don't know what's going on.
Please help because it seems to be happenong more frequently!
This is what the screen should look like:
Solved!
Go to Solution.

If you can find a good "reputable" shop that will offer a free diagnostic, that may be your best option. Usually this is a simple fix if it is the LCD cable. If it is the graphics card, that is more costly, but less than the cost of a new notebook.
You can contact Lenovo directly to inquire on warranty and if it will cover your current issue before you pull the trigger on the repair.
Good luck.

MacBook Pro screen flickers and freezes after Snow Leopard/Safari 5 updates

Hi guys,
I have a silver 120GB 15-inch MacBook Pro from Summer 2007 with 3GB RAM and 25+GB free space which has recently begun to freeze irrecoverably. The first appearance of these symptoms seems to coincide with my installing the Snow Leopard 10.6.6 update via Software Update.
I'm not particularly well versed in computer technology, but will try to describe my problem as detailedly as possible.
What happens is this:
1. I start the computer as per usual, with only a couple of startup items. Everything's fine.
2. I start working. Use a lot of Safari 5 for browsing websites, often with some kind of Flash or "Flash-type" content such as banner ads, videos, even full Flash designs. I may also have programs such as QuickTime, VLC or an image editor open, if not necessarily "actively" doing anything. Everything's still fine - I'm able to both browse websites and watch videos as usual.
3. After a while of active working - say, 1-3 hours - I notice browsing websites gets a little choppy. Display features such as the file list view in Finder may or may not appear properly. The rotating wait cursor may or may not appear from time to time.
4. Immediately after symptom no. 3, the next time I start to watch a video, either via Safari 5 (say for example something on DailyMotion.com) or a file via QuickTime, something goes wrong.
Following no. 4, one of three things invariably happen:
5a) The video freezes and the entire screen flickers from black to the screen view very quickly two or three times, after which the computer or screen appears to freeze. The cursor still moves, but nothing reacts to it - open windows become completely unresponsive, nor does the top or any other menu react in any way to clicking. The "menu row" of application items, which normally appears when I move the cursor to the very bottom of the screen, doesn't appear. Restarting "blindly" by pressing the Off-button once and pressing R doesn't work. I'm forced to do a hard reboot, after which the computer is once again fine until the next two hours of active working. This usually happens ONLY when I try to watch a video in Full Screen-mode.
5b) I notice the video freezing only just in time, and am able to pause it and "esc" out of Full Screen-mode, and the computer remains operational. However, as soon as I again try to play video in Full Screen-mode, everything described in 5a. happens.
5c) The video stops playing, and the screen reverts momentarily to pale blue before switching to the login screen. I login again with my details, and everything appears to be fine again until the next two hours of active working. The computer "starts up" a lot faster than with a hard reboot. This usually happens ONLY when I've tried to watch a video in its original size, i.e. when not in Full Screen-mode.
This happens 1-4 times a day, and it appears to depend directly on how much work I've been doing on the computer. The less I use it in the course of a day, the longer it takes until the next time it freezes.
So, in a way, I'm able to replicate this problem. 95% of the time the screen has frozen while watching or starting to watch (usually already when starting to watch) video footage, but it has also frozen a couple of times just switching between e.g. Safari 5 and an image editor or browsing a website with a Flash banner ad or embedded video content (which however hasn't necessarily been playing); today, the screen froze when I tried to open a website made entirely with Flash.
Although it could be just a coincidence, I believe this issue first appeared when I updated Snow Leopard to 10.6.6 via Software Update alongside some other pending updates, including as far as I recall one for Safari 5. The update process appeared to have gone well at the time, though, and was not interrupted in any way. I have never had this specific problem with the computer/screen before, though.
I've read a couple of threads here regarding very similar issues with newer MBP models than mine, in which it has been suggested that the fault may lie in a malfunctioning NVIDIA GeForce graphics card. Now I've had that replaced already once because my screen went unexpectedly completely blank after a forced reboot 1-2 years ago (I don't remember exactly), but according to my System Profiler info the card still a GeForce 8600M GT. Can it be failing again?
I've also had some kind of a RAM card failure once. As far as I understood it, one of the RAM cards had fried and was preventing the computer from starting up. I replaced the bad 1GB card with a new 2GB one and the problem was resolved. Before the computer died, there were also other symptoms, but they were not similar to these.
I'm also doing the Apple Hardware Test tomorrow. Any other suggestions, though, than the graphics card?
*Could this have to do with Flash or Safari 5?* Just hear me out. Even though my computer has frozen from watching a video in just QuickTime, Safari 5 has always been open in the background at the same time, and more likely than not with websites with "Flash" content open. And come to think of it, before I performed the Snow Leopard and Safari 5 updates, I used to have daily problems viewing Flash video in Safari 5, the video content either suddenly showing up as "Plug-in Failure" or crashing the browser; I've had both Safari 5 and the Safari 5 Flash plug-in "quit unexpectedly" countless times in the past, almost daily. Sometimes the "Plug-in Failure" could be fixed just by refreshing the browser view; at other times, Safari 5 would stop showing Flash content altogether - Flash banner ads (such as Google ads), YouTube and other Flash videos, everything - until I quit and restarted Safari 5. BUT - since the day I updated everything via Software Update, I don't remember this happening; it never gets to "Plug-in Failure" now. Could it be worth trying to use e.g. just Firefox for a while or is there something (e.g. Adobe Flash) that I could try reinstall? Or am I just clutching at straws here?
Thanks for reading this long, long post!

Do you have access to an Apple Store? If so, it may be worth making an appointment at the genius bar and having them run the test for the NVIDIA problem. Since your replacement logic board still has the NVIDIA GeForce 8600 M GT video chip, it could be starting to happen to your replacement logic board.
I also agree with all of CMCSK's suggestions. Freezing is often associated with hard drive problems. You might also want to run SMART Utility:
http://www.apple.com/downloads/macosx/systemdiskutilities/smartutility.html
You can download the demo and run it several times for free. It will give you a very comprehensive view of the physical health of your hard drive. If you still have the original one from 2007, it's getting pretty long in the tooth and may be approaching the end of its average useful life of 3-5 years. I just recently had to replace my original 2007 Fujitsu drive.
If your drive is headed south, and is also too small, it may be time to upgrade to a larger and faster drive.
The software update probably didn't cause the problems, but it may have exposed problems that were already in existence.
Good luck!

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,
Roger

Screen flickers, occasionally goes black

Hello all,
iBook g4 bought refurb - 2-3 years ago...
Occasionally the screen is flickering and I have had two occasions where the screen just went black but I could still see the desktop. Had to force restart. I have had 2 times where it was looking for the startup folder after restart as well.
Looks like it might be time for a new laptop??? I have had no other problems.
Haven't noticed the fan running a lot even with several big programs open either.
Searched flicker on this forum and didn't get much.
thanks,
Al

Tried to delete this post since it is doubled but no luck.

Richard, I don't think it freezes when it GOES BLACK. I have had freezes at other times but when it goes black I can see my cursor move - fairly certain.
One difference is that my fan doesn't run alot - in fact I can't remember the last time it ran- if it isn't running at all then that should be a big clue.
have not tried external display....
my projector is broken...
can I use my iMac as external display.
I have the mini vga that came with the ibook.
will check that other thread.
thanks,

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:

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.

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.

Screen flickered, then went black (faint windows can still be seen)

i was just working on my powerbook and my screen flickered on and off and turned black. the best way to describe this is like what a lightbulb does right before it blows out. what is wrong?! i am trying to type this as fast as i can before it starts doing it again. is my LCD frying?

Might be bad Power Management Unit settings - following instructions to reset PMU.
Otherwise, there are 3 likely hardware related causes:
1. Failing LCD Display backlight - needs replacement
2. Broken/Intermittent ribbon connection - needs soldering and/or replacement
3. Failing LCD backlight Inverter - needs soldering and/or repalcement
For all 3 of these screen would require service for technician....call Apple if you have warranty.

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
Tom D.

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?

TS3274 I have a new iPad mini w/retina display. Recently, the screen flickered with red lines across the entire screen. Anyway, the screen eventually went black. Now it does't work. Anyone have any suggestions?

My screen just went haywire. The screen flickered with red strips vertically. I thought it was part of the game I was operating until the screen went black and a white strip illiminated at the top. I tried turning teh system off, but it would not allow me to turn it off. After about 5 minutes, I was able to turn it off. Anyone have this occur? The Ipad mini appears to be ok now.

I Also have this problem!!
In my situation, the screen simply started exhibiting the same symptoms a few weeks ago (early February) for no apparent reason. At first I thought the screen was dead, but discovered the heat solution by accident. Now I turn it on and keep it from going to sleep until I go to bed. Thank goodness the battery is still awesome on this thing.
I bought it new and still has the original screen, I keep it at home (never below 62 degrees). Coincidentally, this happened a day or two after the expiration of the warranty!! Any help figuring this one out would be eternally appreciated.
iPad mini retina Wi-Fi, iOS 8.1.3
