Desktops :: Black Line On Screen Appear?
Aug 14, 2010Recently, a vertical black line (maybe slightly dotted) appeared running down the screen of my iMac G5 (Power PC processor). On the left of the line the screen appears fuzzy while on the right it's OK.
Has anyone experienced this before? Hope to hear from someone who has.
Desktops :: Mac Pro Goes To A Black Screen When Idle And Won't Restart?
Jun 20, 2009Recently my Mac Pro has been going to a black screen when idle for a while and I need to power off using the power button and restart. It's not set to ever go to sleep but if I use the sleep function under the Apple, it functions as it should, waking when I touch a key (although I don't let it sit for a while before I wake it). When it is in the black screen mode, it still is performing Time Machine backups.

Aug 11, 2009The screen/crt of the imac that I have been using since about '98 went black - this actually happened a couple times previously but I was able to get back in (no idea - one of those things where out of frustration you just start pushing everything at once and it suddenly pops back on). I have tried everything - the internal battery, that little button on the motherboard (not sure if that is what it is called) that resets everything, the connection of the main power button on the front, etc. I am fairly sure it is stuck in sleep-mode or something (no beeps, hard drive doesn't make the usual booting-up sounds but you can tell that it is receiving power) but after months of wasted effort I finally gave up. I bought another slot-loading G3 and would like to swap hard-drives between the two - I have taken my old G3 completely apart so many times that I am totally comfortable with that aspect but have hesitated because if I somehow blow this one I will be left with nothing.

OS X V10.5 Leopard :: IMac Screen Went Black - Starts Up With Black Display
May 24, 2012I came back from work to wake up my iMac. It made the noise but the screen stayed black. I tried restarting by holding the power button- I can hear it start and the chime but still have a black screen. I tried resetting the pram, and unplugging the cord but I still get a black screen. I can hear the chime though; I'm not sure if that means anything. I just had the hard drive replaced in February so I hope it's not that. just wanted to clarify that when I restart, I get the chime but the screen stays black- I don't get to the grey screen. So I'm assuming right now that my display may be shot?

View 1 Replies View RelatedDesktops :: Ibook G4 1.42 Dark Screen New Inverter
Jun 14, 2007I got a cheap 1.42ghz 512mb RAM, 14" screen G4 ibook because it had a broken hinge. I tore apart the laptop and replaced the hinge (screen frame) and put it back together. The screen wouldn't work. I opened it back up and found that the video connector was lose, so I connected it and put it back together. BAM!! Everything worked... everything except the sleep feature when the lid is closed. So I opened it back up, took the magnet from the old frame and put it on the new frame (which was missing its magnet).
When I turned it back on the screen was blank/dark. It showed all the signs of classic inverter board burnout (dark screen, can be seen with flashlight from behind, can be seen on external monitor), so I ordered an inverter board and when it arrived, I swapped it out. Still nothing. The next idea would be the backlight, but that doesn't make sense... I'm trying to figure out what might have happened to make the inverter/backlight go from working fine to not working when all I did was removed the screen back case, screw on the magnet and close it up. I have done a bunch of digging around under the hood and am wondering if anyone knows of a possible ground wire, other connection, easily broken wire, or other issue that might have happened. I'm thinking that it might be one of the power wires that goes into the inverter. It might have broken inside the shield, or maybe I was sold another bad inverter board.
So:
Assumption 1: one or both inverter boards are good.
Are there any connections other than the inverter data/power cable from the mobo and the cable from the inverter to the backlight?
Does anything else (backlight, etc) have to be grounded? Where are these groundings?
Would anything else give the same symptoms except the inverter?
How can I test the backlight? I heard that there are two lights in these machines, so if it was one of the florescent lights, only 1/2 the screen would be dark.
Assumption 2: Neither board is good and that is the problem.
How can I test the inverter board (short of an osilascope) to see if it's working?
Is this a good assumption?
I'm about stumped right now and haven't found any direct help on forums. I'm hoping someone in the Mac community has run into this or has an idea about what could be going on. I'm really hoping that I missed something like replacing a screw that is also a ground or something along those lines.

PowerPC :: Load Up The Blue Screen With The Apple Logo, But Then The Screen Goes Black Or Flickers?
Feb 4, 2008I am looking at purchasing an Ibook G4 but the description of the item includes this:"When you switch it on it begins to load up i.e. the blue screen with the Apple logo, but then the screen goes black or flickers. Said friend has kindly wiped the hard drive for me so now when you switch it on it makes the �opening� noise then you get a blue screen with alternating �?� and the Finder logo."
I have a feeling this may have been a temporary fault with the screen connector being loose and possibly damaged.But i assume the alternating "?" and the "finder logo" is simply a lack of OS?

Sep 16, 2009So I have a DYNEX 21 inch HD TV conected up to my MBP via the VGA connection route. My problem is that when I want a program (or more specifically in this case a game) to go into fullscreen mode it automatically goes to my primary monitor and turns the other screen black. I know I can switch the primary monitor from my actual laptop screen to the TV however I just want the game to be full screen on the TV while still having access to my dock and everything on my laptop.

Jan 4, 2010I have a problem with my screen - when there is something black on, I can see a faint mark of a lighter colour. I have tried to take a picture, please excuse the poor quality. There is nothing visible when the screen is off, even under close examination. Is it less visible when lighter things are on the screen, and invisible when the screen is white.
No drops or liquid spills. Will this go away on it's own? Any fixes?
PowerPC :: IBook Screen Not Working At Startup / Screen Remains Black
Apr 30, 2007My iBook will not display anything on its screen. Rather, it just remains black. One time, the screen did come on, but then shortly after booting, it flickered a lot and then went black again. A year ago, something similiar happened and when I took it to be serviced (when I had AppleCare), they had to send it away and have a new logic board installed. Now this machine is out of warrenty and and I am not sure what to do, or even if it is the same problem. Any suggestions?? Thanks!

Sep 10, 2014As the headline says the right half of the screen turns black when watching video content in iTunes on full screen. I can see the whole picture when moving the mouse a little but as soon as the navigation bar disappears the right half of the picture disappears too. It does not matter what source it is. Both podcasts and movies work (or do not work) the same.
The problem doesn't occur for other player (VLC, XBMC etc.).

Desktops :: Computer Boots Without Showing The Gray Screen With Apple Logo?
Mar 2, 2010I'm noticing some weird behavior in my Mac Pro first gen.
Basically, when I start it up, the displays just stays black for some time, until the Desktop loads up and the computer is functional, but never displays the gray screen with the Apple logo. This just happened all of a sudden and stayed like this.
I know is not a big deal now, but I'd like to sell it in the near future and this could be problematic for that.
Desktops :: IMac G5 - Blue Screen Appear And The Normal Log On Profile Selector Doesn't Appear
Sep 29, 2010Over the last few months there have begun to be hundreds of blue horizontal lines running across the screen and the sound fragmented, with the Mac crashing over 5 times a day. Normally, I would restart and the problem would be OK for a while.
However, now when I turn on hundreds of horizontal black/green lines appear in colums, the normal apple symbol comes up with the spinning loading item. Then a blue screen will appear and the normal log on profile selector doesn't appear. Then after a while the blue screen is covered the thousands of these black/green lines.
