My screen is randomly getting darker.

Every few seconds my screen gets a little bit darker for a few seconds and then reverts back to normal. When the screen is darker it has patches that are darker than the rest.

IIt could be a damaged video card, but first of all try resetting the SMC:
Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
ANd if that has no effect, reset the NVRAM:

I have a late 2009 imac i am having issues with my screen flickering and getting dark

i have a late 2009 imac 21 inch i am having problems with my screen flickering ND GETTING DARK DOES THIS MEAN THAT MY COMPUTER IA FAILING

I have partly the same problem (Sceen blackening) sparodically.
2010 iMAC with I7 CPU and ATI Radeon HD 4850 512 MB Graphics.
If I lower the brightness to around (3 or sometimes 4 of the on screen squares F2) the issue does not happen at all. I prefer a bright screen.
The issue commenced immediately after instaalling OS X 10.8.2 update one year ago.
The current software is OS X 10.9 (13A603)
The graphics on this computer are always first rate when working properly even at maximum brightness
There are particular days and times when the problem routinely occurs.
Some of my neighbors with iMacs have similar problems.
I live adjacent to the City of London in an area where new building seems to be developing faster than the various utilities and there are known Power Network issues. Professional surge supressors make no difference.
I live in a large property with four independent ring mais. The issue is present on all four rings. I have yet to take the computer elsewhere to possibly eliminate power issues from the problem.
I am reluctant to replace an otherwise fine top of range iMac which otherwise serves me well since the same problems might be present.

Screen flickers then gets darker on top.

I have an early 2008 20"Imac, and I also have the 10.8. Hmm, I wonder if that is the problem, I thought it was my invertor board. No warranty on this either.
My screen flickers then the top stays a litter darker.

Have you read for possible solutions over in the "More Like This" thread over here?----------------------->

In the midle of a song the screen gets dark, then suddenly appear the home screen of ipod and the song stops.

i have updated my ipod 4g to ios 5.0. everything went great, but something is not right cause sometimes in the midle of a song the screen gets dark, then suddenly appear the home screen of ipod and the song stops. help-me, what should i do?

It occurs with both ripped songs and ITMS songs, but not always the same songs. Just this morning, I had a song skip ahead, then put down the ipod for a few mintues, came back and that same song did not skip ahead at all. I've been on a stretch now of about 20 songs with no skipping whatsoever. Hmmmmmm....
I've used all the five "R"'s multiple times to no avail. It just seems so random, it frustrates me.
Thanks for the help, King

Iphone 5 randomly gets blue screen. Will not turn on after I tried to restart it.

I have had my Iphone 5s since about a month after they came out. It has worked perfectly up until now.
While I was at work I was going about my regular business using my phone as usual. I put it into my pocket and about 15 minutes later pulled it out to check it but all that was on the screen was a dim dark blue light. I couldnt do anything on the screen including turning it off so I did that hard reset (holding the Home and Sleep button).
After the phone shut off it did not turn back on. I tried every combination of buttons and reset options.
     -(Home/Sleep buttons)
     -(Home/Sleep buttons +Volume up and down)
     -(Home/Sleep buttons while turning the mute button on and off)---This one was just a theory online, same as the one before it.
     -(Restored the iphone multiple times in itunes)
I had the phone plugged in for a good amount of time and while it was charging it would periodically do a quick 2 vibration burst, like it was starting to connect.
Im guessing its just not getting past a point in the restarting process so it just doesnt continue, seeing as it is still accepting a charge (Itunes put it at 68%)
Anyone have any theories or explanation as to why this could be happening? I appreciate any response
Thanks

Try to put the phone in recovery mode and restore it. If that does not work, take it in to an authorized service provider or Apple store for service. It is still under warranty.

Ibook g3 screen getting darker

Hi, my ibook g3 screen is getting darker and darker. Yesterday I was able to see my wallpaper on the background, but today it's almost completly gone! The HD seem to work fine, I don't think it's a logicboard problem (I had to deal with that about two years ago), and it open and close as usual. Do I have do replace my screen?
Thanks for the ansmers

Have you tried resetting the PMU? The PMU (Power Management Unit) has control over the backlight function, so resetting it may help.
<hr>
If not, sometimes the inverter cable causes a black screen (no backlight). If this is what is wrong, the display may work at odd angles. Try opening (and/or closing) the display a bit to see if that helps.
If that doesn't help, it sounds as if you may need to replace the inverter board. I'd be inclined to think this is the problem because your description seems to indicate a gradual loss of the backlight.

Screen gets darker

I cant find anything like this on the forum but perhaps I just missed something. For months now every 2 or 3 weeks the bottom right, bottom centre or the whole screen gets a bit darker. Normally if its part of the screen it get better after an hour but after a while even that does not happen. In the end resetting the PRAM or PMU is the only way to go to sort it out. I calibrate my screen every few days but always check before doing so that the screen has not gone dark again. Now I think this all started when bluetooth did a vanishing act as well. The computer tells you the hardware does not exist any more! This all started after one of the many 10.3 updates. Might not be all related to each other but thought best to mention it. Any ideas? When I say the screen goes darker I mean it goes greyer. There is no colour tints.

Thank God other people have noticed this probelm as well! I too have been having this problem for about the last two month. Though, I noticed it after I purchased my iSight camera. I would certainly hope that this issue can be resolved quickly and does not become another "nano-issue."

Shortly after starting up, a dark 'film' slowly comes down over the screen and I get a message saying I have to shut down the computer. I've tried to start from the disk, and before I can even run a repair off utilities, it happens again. What's up?

When I started my iMac today, it started beeping like an alarm horn. I shut it down, and held the startup button a little longer to get it to start. Shortly after starting up, a dark 'film' slowly comes down over the screen and I get a message saying I have to shut down the computer. I've tried to start from the disk, and before I can even run a repair off utilities, it happens again. What's up? Am I screwed? HELP!!

What you are seeing is a kernel panic, often but not always connected with a hardware or peripheral issue, so, unplug everything except mouse and keyboard, reboot and hold the shift key as soon as your hear the chime, continue holding it until you see the Apple Icon and spinning progress indicator, then post back.
It will take noticeably longer than normal to start.

Screen Getting Darker

I have a 3.06 GHz Intel Core 2 Duo that i bought in November of 2009. i've noticed in the last month or so that about have of the screen is a little bit darker. there's more light on the right side of the screen than the left side. Does someone have an answer to this? thanks.

JMVD,
Seems to me that you're quite the Apple expert. I had this problem with my eMac. Since, I am not American or English I hope I can make the problem chrystal clear.
I think I had the same problem with my screen. A few days ago I left my eMac running while not using it. After a while the screen became dark due to the "sleep modus setting" of course. This is not the first time this happens. Only this time after activating the eMac again my screen was so much darker. So of course I changed the screen setting (calibration) at the system preference menu. It improved the brightness of the screen but I noticed that it still was not normal. I said to myself: as long as I can work with it than it would be no problem. But then last night I forgot to shut down my eMac and again the screen got darker. This time I tried to change the setting again. Again the calibration process but I saw that I am using the maximum brightness and I got irritated by the quality of the color. And furthermore if the screen would get darker the next time I already used up the calibration / brightness possibities.
So I went looking for help at the apple site. And I found your discussion. And I just tried the command option o f advise of yours etc etc etc. After the automatic restart only the grey screen (background) with in the centre the apple logo appeared.
Your advice was very simple so I just went for it. I hope I did not erased the whole unit. Please tell me what I should do know. Also I saw the screen (grey back ground / apple logo) was kind of dark. But, I never look at the screen when I start up the eMac. Maybe I am imagining this.
I hope you can help me with this. Unfortunately, I do not have the apple care protection plan.
Thanx.

Is your screen getting darker?

Is anyone else experiencing the screen on their MacBook Pro getting darker and darker? I can't brighten it up with the contrast button, and while it's not totally black - it's really dark and hard to see. I tried downloading this correction:
http://support.apple.com/kb/TS4088
But when I try to open it, it says that this file isn't supported on my computer. FYI - I'm got a MacBook Pro, and am running OSX 10.6.8

Asking if anyone else has seen this isn't likely to get you anywhere. If you find out someone else has seen it, you still haven't learned anything other than that someone else has had the same problem. If you're wondering if it's a common problem, it is not.
As to the update mentioned by that link, that sounds like a different problem. And if it won't install on your machine, that's because your MBP is not one of the affected machines. Updates like those will only install on specific hardware.
From the sounds of things, it sounds like your backlight is failing. I would take it to an Apple Store or call Apple Support ASAP.

Ipad screen getting dark fast

The screen on my iPad turned pink a couple of days ago and now it's getting dark fast. I've tried everything I can find out here:
I check the brightness and it's all the way up.
I reset it.
I plugged it into a computer.
I put my knee into it. Lots of people thought that was a miracle remedy.
I can't afford a new iPad. Please help thanks.

Is it still under warranty? I'd back it up and make an appointment and take it to your local apple store. It sounds to me like the screen or backlight is dying.

Emac screen getting darker with time?

ive had my emac now for a little over a yea...about 14 months to be exact. in may i noticed that the screen was getting considerably darker to the point where i could hardly see anything. so i calibrated it to lighten it up. it worked and then got even brighter and kinda back to normal. well this weekend it got seriously dark again. i recalibrated it again and now its somewhat brighter but the picture is still way to dark and looks like garbage. im very frustrated as i thought that it may just get better with time again as it did in may. any suggestions from anyone would be great!!!
