Recently, 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.
I have a Powerbook G4, and noticed a line (a thickness of a hairline) on my monitor displayed horizontally, about a length of 1/16 of an inch.
I know it's very tiny but I wanted to know what's causing this and if there's any way to fix it..
When i turn on my mac pro the screen will not turn on but my mac pro is booting up. How do I trouble shoot?
View 1 Replies View RelatedRecently 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.
View 7 Replies View RelatedThe 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.

basically i bought my macbook literally two days ago and it worked perfectly for the first day and it still does except for the fact that there is a mysterious black line on the screen that appeared from nowhere! i have tried restarting it multiple times and i have never touched the screen violently...when i take a screen capture it doesn't show!!! i could swear I've never even touched the screen.
View 1 Replies View RelatedSo today I noticed a small black bar on the corner of my screen. I tried to get a screen shot of it, but i couldn't, like it was off the screen. However, my mouse dissapears under it when i move it there.It is a little hard to distinguish because it is the 2.4 ghz macbook aluminum, glossy screen so it has the black surrounding it, but it is definably there. This all along the right hand edge of the screen.
Although there is a chance it may have always been there, I am not so sure. I think there are lines along the top and left hand sides, but they are much smaller. again it is hard to tell. I am fairly sure that there is none on the bottom of screen. Is this normal, or what? I have applecare, and I didn't do anything to my macbook. Although it is getting me a little OCDish, and is slightly annoying, and I know these things on the screen tend to expand.
I have an iMac 2.8 24 inch, about Two years old running 10.5.7 , when I start the computer it shows the normal Gray screen for about 30 seconds, then the screen goes all Black , but with a small flashing white line ( _ ) in the top Left hand side corner.
It just stays all Black for ever , I then hold down the On / Off button and turn off the computer, I then hold down the keyboard '' option key '' and press the on button at the same time , then I get the option to start from the main HDD , I click the Icon and the computer then starts normally , and every thing runs ok.
Can some one please tell me what I have to do to get my iMac to start up normally again , Ive run Repair Disk permissions but the problem still occurs . Over the last few day's Ive been trying out a few new applications, so not too sure if this has any thing to do with this current problem
I have a core i7 MBP with the high res display, and when the display is showing black, a horizontal green line appears on the screen. It is only visible when the screen is showing black or another very very dark color, and the line is not visible with the screen off. It isnt something on the screen, as rubbing it does not affect it at all. I cannot post a screenshot of it, because it does not appear in the screenshot (it does on my screen, because the line is there physically, but on other monitors it is not visible).

I have had my MacBook Pro since November so it's still new. I take great care of it. This morning, I opened it up and noticed a small black line present under the screen. It has not been dropped, moved, beaten up, etc. It doesn't look like a broken pixel and all of the dead pixel fixers I have tried have not worked. Not sure what to do now. I live two hours away from the closest apple store and I cannot afford to send it out for fixing because I am an online student and need the computer daily.

I have 2 pictures which i snapped with my iPhone, so i will link you too them.
The line is not majorly visible, but it is just annoying considering i payed �1000 for this iMac.

My screen had black and white vertical lines pop up over the entire screen then went blank and now at a restart the password then loading spinning circle happens then I get a blank white screen.It's a 27 in Intel iMac that is about 2011/12 purchase

I have only recently started noticing this, it is mostly visible on the white screen at boot up but just faintly noticed it now against my background.
It is a fading black line going down the left hand side of the screen, it starts at the top kind of fades in the middle then comes out again.
I honestly have no idea what this is, i will try catch a picture on my phone soon and post it up.
Cheers.
UPDATE: Sometimes the line is clear, sometimes it is faint and even sometimes it isn't even there!
Soo...I just picked up a mini to run plex and use as a media center. Hooking it up to my projector via VGA cable. When I set the display settings to the native resolution on the projector there is a small black line or bar down the left hand side of the screen. Not on the right but only on the left. why this would be happening?
View 6 Replies View RelatedI've just installed the BRL-CAD application and it need a command line input (/usr/brlcad/bin) to the System - see below. I am not that familiar with the commands although no problem getting into the Terminal. I just don't want to screw this up. I am running a Mac Mini, 2.66 Ghz Intel Core 2 Duo, 4 GB RAM, OS 10.6.5. I need some step-by-step info in getting this embedded and the application up and running.
Setting Up the Path:
Once installed, you will need to add /usr/brlcad/bin to your system
PATH. For Bourne shell users, you can run the following:
PATH=/usr/brlcad/bin:$PATH ; export PATH
For C shell users, this should do the same thing:
set path=( /usr/brlcad/bin $path ) ; rehash
After moving I setup the Mini, but got nothing from the monitor. Reset PRAM & PMU, nothing. CPU chimes, etc.work, but the only thing I get from the monitor is a yellow square with a brief message indicating there's no signal.
It's a Mini, 2 MB RAM, Core 2, OSX10.5.x, it's less than a year old. The CPU appears to be OK. Monitor is getting power.
Before I log into my iMac there is a black curved line on the left.

I 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?

there are two things that the macbook is doing to me. one is that sometimes when i move the screen up or down (the hinge is rather stiff) a white (thin) line flashes across the screen. but recently, while randomly browsing through the internet, the screen almost... i guess faded to a gray screen, but like gradually, and not like a kernel error, like the display just faded away. happened twice in a row, did a battery pull and now wont do it again.

I've heard about computer monitor kits where you can transform the monitor into a touchscreen for PCs. Does such a kit exist for Macs ?
View 1 Replies View RelatedI 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.
I teach in a computer lab with 30 Duo Core iMacs running 10.5.4. Occasionally I will have a screen that begins flashing off and on. The computer should have gone to the screen saver.
