MacBook Pro :: Dark Display On OS 10.4?
Mar 31, 2012My six years old MBP OS 10.4.x Tiger all of the sudden the display turned black. I hardly see the content of the desktop only when there is some light on the room, looks like I have reduce the light to the Display. I have tried to reset the PRAM with the opion, ctrl, P, R key combination and it did not work. It boots-up OK, no problem with the HD neither Memory, I have not run any test on it though. I have not had any trouble on my MBP until now and I have to say I have never reinstalled the OS.

Laptops :: IBook G4 Display Goes Dark
Aug 11, 2009I have an iBook (OSX 10.3.9)that's been great for the last couple of years. However the last week or so the screen goes dark for no apparent reason. You can still see through enough to fiddle around and hit shut down...and after it shuts down, and I restart it...it seems normal...that is until the next time. It's happened about 4 times in the last three days. A couple of times on battery and once plugged in I think. It's like it goes to sleep but you can't hit the space bar to wake up. Also seems like maybe an energy saving deal gone awry.
Now for info that may be pertinent: I dropped this laptop(in it's case) about a year ago. Holy crap..all docs would only read in magenta. No black no color only magenta and a "photograph negative" looking image for background or any graphic. I was sure it was dead duck and fried but kept trying it periodically. After about a month, after giving up...I turned it on and it was fine...as if nothing was wrong. Weirdest deal. It's been fine ever since.
I thought perhaps I was too lucky...and assume this may be a result of that fall.
MacBook :: Dark Spot On The Display
May 15, 2009I have a dark spot on my MacBook display of diameter 0.15 inches (or 4 mm). The spot is bright if looked from an angle.I brought my Mac to the Apple Care and I just received the verdict: the spot was caused by ME by applying extra pressure to the LCD!. Which is not covered by Apple Care warranty!
That's interesting since I am 100% sure that I didn't harm the screen. The guy even suggested that I forgot my pen on the keyboard and closed the laptop! That's great!
I told the Apple guy to send me back the laptop as it is after he offered a repair for $700 plus tax! But I am determined to go on with this since I love my Mac, I spent a lot of money on it.

Hardware :: Display On Macbook Very Dark And Inaccurate?
Feb 16, 2008My macbook has had this problem for a while but I have lived with it so far, but now it is really annoying me. Images and video are displayed very darkly, often loosing a lot of detail and maing the image un-seeable. I have tried fiddling with the gamma settings and all other settings that I can find on the control pannel, but so far I have had no luck.
Just as an example, this is a frame from some video I shot:
click for pic
On any other monitor, the bulb appears bright and white and the ball bearing is visible. On my monitor the bulb is very dark, most of the fragments are invisible and the ball bearing is just a small crescent of light.
MacBook Pro :: Screen Flickering / The Display Goes Dark, Almost Black, For A Second?
Sep 5, 2010So I've got my MBP that I've had for about 4 months, the thing is. It just recently started to have screen flickering issues. I'll be sitting doing w/e as usual and all of a sudden the display goes dark, almost black, for a second, then comes back up again. I have yet to find any trend in when this is happening, but it is definitely happening on battery as well as plugged in, but it seems to be getting worse.any one have any idea what this could be, something I can fix on my own, or should I take it in?

Dec 13, 2010Just picked up a 11.6" MBA this past Saturday. I am noticing an interesting display "issue"... I wanted to confirm that other's are not seeing this before I take it back to the store.
On the bottom of the display, there's a strip, maybe 2-3mm worth, where it is darker than the rest of the display. Are any of you seeing this behavior as well? It's particularly noticeable when when using solid background colors.
PowerPC :: IMac G4/17 - Sunflower - LCD Display Is Dark - No Image
Jul 30, 2007I replaced my iMac G4/800 17" hard drive that was failing (S.M.A.R.T. status) tonight. Textbook operation, following directions from xlr8yourmac.com. No problems at all. I pre-built the drive with Tiger 4.10 in an external case (using the iMac as host) and transferred everything to the drive and tested. I booted off the external drive for a few days for testing. Again, no problems.
I got the iMac back together and booted up. Everything sounds fine but the monitor is black. It's as if there's no power to it or perhaps the lamps were just out.
When I press the power key for 1-2 seconds, the mac goes to sleep and the white Sleep Light on the front of the monitor comes on, so the monitor would appear to be getting power.
The Mac is working, evidently, as the chime for new mail sounded and the new drive chirps a little (very quiet though, btw).
I do NOT have a second monitor to hook to the VGA port, unfortunately.
On one reboot there was a sine-wave 'bong' sound, but the Mac proceeded to boot. I shut down again after that, took the housing apart and checked for trouble. Nothing. The video cable and connector is fine. There are no cables pinched or cut that I can see. And I did ever-so-carefully align the two halves when reassembling.
On the third boot I got the normal Mac chime (no bong/gong) and it booted fine - with no video.
One side note that I expect to be un-related: I left the HD jumper in cable-select mode, as the drive that was in there was also set on cable select (was a Western Digital 250GB drive; the new drive is a Maxtor).
What's wrong with this iMac monitor?
OS X :: MBP Shows Dark Display With Thin White Stripe?
May 4, 2009Recently, the display of my MacBook Pro (unfortunately, out of warranty) often is black/greyish after wake-up/start-up with a thin white stripe in the middle of the screen, and the computer (obviously) cannot be used in this mode (you can hear it start up, but since the screen is completely dark, I can't actually do anything - restarting doesn't help either).
At first I thought it might be the graphic card (since there is a known problem with NVIDIA), but I've brought it in for repair where they have run multiple software-tests, and no error code was returned (when I brought it in it magically "fixed itself" and, once running, the problem can't be re-recreated), so nothing was fixed.
It seems to me that the MacBook for some reason cannot find or communicate with the display because I just discovered that if I hook up an external monitor, it manages to find that, and, after disconnecting the external monitor again, also "reconnects" to its own display. It then generally runs fine until I physically move it (ie. put it in my backpack and carry it somewhere) - after being moved, it tends to have the same problem again (not always, but more and more often).
Have you had any similar experience and/or what might cause this and how it could be fixed? I'd like to avoid replacing the display or something of the sort until I know for sure what's going on.

Aug 14, 2010After months of an incredibly slow internet connection @ home I finally discovered the problem. I have a MacBook Air 1.6 GHz Intel Core 2 Duo. It can connect to any wireless network at home, school, office, etc. However, when at home I connect my Macbook Air to a 23" Apple Cinema Display (ACD) the internet goes from 1500 Kbps to 60 Kbps. Not believing the reason I have tried it several times and there is no other factor. At home I use a 2701HG-T 2Wire router.
Updates:
1) I do not have a network adapter so I can't know if the same would happen with Ethernet.
2) The problem exists whether with my MBA is opened or closed.
3) I do not change the location of my MBA when I connect it to the ACD.
MacBook Air :: Slight Flickering Only On Dark Grey On External Display?
Sep 12, 2010I have a 28" inch display attached to newest version of Air. Works ok except when I have a full screen on plain dark grey background, then I see a waviness or flickering effect. Like the dark grey in Iphoto background. Other than this, the other colors seems ok. Pictures are fine, even when dark. Maybe there's a slight flickering with dark blue. Any explanations for this.
using mini display port to dvi. Tried with a friends dual link display, was a little different, but still unstable looking in dark grey when it fills the screen.
Could it be just what it takes to make this color, or the Hertz, which is 60. Other than this, no problem with the screen.

Jul 3, 2012I cannot look at any website that has a lot of photos for too long without the mac locking up. I have tried Google chrome with the same results as Safari. I looked on the forums and saw a flush cache command through terminal and tried that with no luck. I don't know if there is anything like the windows task manager to just kill the one app without rebooting.

Safari :: Flash Videos, They Are Only Display In "Private Browsing" Mode In 5.1.7
May 13, 2012The symptoms is: The flash videos are only display with a full red bar and nothing happen, no video no sound nothing. The Flash player was upgrade with 11.2.202.235. before safari 5.1.7. I have an iMac with SL, and a Macbook with SL too. However after I upgraded safari 5.1.7 the flash videos are not display correctly, (only videos). The same happen in both computers. I need to tell you that I follow all the possible recommendations that I founded in internent. I uninstall flash pug-in many times. I restore both. I switch many buttons and options like "reset safari", "empty cahe", "block pop-up windows", "enable java-script", "enable java". I turn off and on the firewall. I switch all the options in the flash player plug in preferences. And nothing. I turn on and off the plug ins. In fact I tried all the possibilities in the preferences menus from the programs.
In one occasion I had a glimpse of functionality for only one hour without problems after I reinstall safari from the Apple website, but only worked until I turned off the computer. The next day was the same problem. After I fought with safari 5.1.7 and the plug-in flash player 11.2.202.235. Now I noticed something wired, only when I switch the "Private browsing" option in safari is when the videos are displayed correctly.

Intel Mac :: OS X Screen Randomly Goes Dark
Feb 4, 2012my screen is just randomly going dark. its not shuting down - just seems to go to sleep but nothing I do wakes it short of turning the power button off then on. When I do that it quickly comes on again and seems to work fine. Seems to be happening with more and more frequency and is not particular to any software. I've read the boards here - I'm not a gamer ( no games on this computer) I'm a photographer with lots of files and I use photoshop alot. Yesterday I was on you tube and my screen went dark again but the video was still playing - I could still hear it. In fact, I could hit my mouse to stop and start the video but I couldn't see anything.

Intel Mac :: Dark Splotches On LCD After Moving?
Jul 2, 2012My wife has a 2009 27" iMac that has been perfectly fine since we purchased it. I had upgraded my old Macbook Pro to 8GB of ram and had the old 2GB sitting around. It was DD3 1066 just what hers took so decided to put the ram in her machine. Shut it down, unplugged all the cables, flipped it over on a towel and inserted the ram. Booted it up and now I get this same effect as the pictures in this thread: [URL]..
We took our own pics but they did not come out well. Both the upper corners have this. Never had an issue before and we are in a climate and humidity controlled room. Obviously the machine is out of warranty but I know this was a problem before on 27" models. Literally it was fine, turned it off, put in the ram, flipped it back over, and turned it back on then the spots were there.
Has a real root cause ever been found for this? Worth it to pull the glass and check the screen itself?

Intel Mac :: Screen Went Dark After Power Interruption?
May 25, 2012My son's imac screen went dark after a power interruption (someone turning the computer off by pulling cord out of electric socket) and I can't get it to go back on. I've already tried depressing the "command, alt,p and r" keys to get a restart, and while it did restart, still no picture on the screen. Occasionally you can see white staticy lines, but mostly it is just dark. I've seen the suggestions to update software and back up data but that isn't possible as far as I can tell because I can't see anything on the screen - it is totally dark!

View 2 Replies View RelatedMacBook :: TV As External Display Suddenly Displaying Only Thousands Of Colors?
Oct 26, 2010It's been a while since I've hooked up my MacBook (late 2008 aluminium) to my TV (Samsung LE40M87BD), to use the latter as an external display for watching a film. Tonight I did it once again, and to my dismay the TV was displaying only thousands of colors. Maybe even only 256, I don't know. It's not a changed setting in my TV, as I've looked through its menu and couldn't find any option that would force it to display the millions it's certainly capable of.
After seeing this weird issue, I opened System Preferences. I looked in the Displays preference pane, but since some years Apple allows no manual control over the color depth anymore. So no luck there. I tried restarting, but that changed nothing. It outputs a correct 1080p 50Hz (PAL) signal, but the colors are just all wrong.
How can it be that my MacBook always used to perfectly display millions of colors on my TV, but now suddenly doesn't? I'm using Apple's own Mini Display Port to DVI adapter, and then a DVI to HDMI cable, which always worked problem free. So it's not the cables, I think. It has to be something in the hardware or software. I'm hoping it's software, otherwise it will be a more serious problem. I haven't tried BootCamp yet, but will do so tonight, just to see if Vista will output millions of colors.
OS X :: 24" IMac Display Suddenly Changed To Max Contrast Or Tint?
Jul 9, 2010I was plugging along on the internet when I decided to try the spoken commands for the first time. When I opened System Preferences and clicked on the microphone, at that instant my screen flickered and changed in both quality and what appears to be contrast and tint. I tried in vain to correct this by way of the controls for the Display in Sys. Prefs. but to no avail. I would like to know if I have a video problem or a memory problem.
