IMac :: Have An Inch Wide White Stripe On My Screen?
Jun 11, 2008
I have an inch wide white stripe that runs from the top to the bottom of my screen. This is on an Imac. The cursor disappears when going through it but pops out on the other side. It doesn't move but I can drag my window back and forth to view the part the stripe covers.
Any ideas or should I locate a local mac repair person?
this morning i turned on my comp and everthing was fine, but then my son started to watch something on youtube and this blinking stripe appeared i thought it was the youtube image, when he closed it, it was my comp screen!! the sun hits directly on the back of the comp, and i've been told that it could damage the comp, could that be it? i have a mac os x 10.4.11.
Recently, 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.
So my 20" 2.4 Imac crashed on me twice tonight. A box popped up telling me to hold down the restart button for several seconds to restat. The second time I did this it just sits with a white screen and give three loud beeps over and over. Is there a fix for this? Is it my ram? I'm at a loss.
My step mom has an iMac. The first gen intel one and the other day out of nowhere there was a white screen with a folder on it and now when you go to start up the iMac the screen just stays white.. What would be the cause of this and what should I do to fix it .. thank you
hey my friend is having a problem with his imac when he turns it on he gets a grey screen and stops there. there is also a grinding noise near the back maybe the hd or disc drive? it grinds 10 times then stops then continues for a couple minutes and then he gets a question mark on the screen.
The screen randomly turns black without any major reasons. It doesn't seem to be a sleep mode/screen saver thing as the music continues to play on. I can adjust the volume or pause the music with the keyboard but the screen just won't turn back on. I have to shut it down using the power button and it happened several time the last couple days. Anyone else experience the same thing and got a solution?
My lovely cat recently decided to walk around my desk while I was at work and knocked over my Imac, causing a large crack in the glass and the screen. I'm not technically capable enough to do the install of the screen/glass myself, but I was wondering what I should expect a repair from an Apple certified technician to run.
A few months ago, i noticed what looked like a streak across the screen, but it wasnt on the outside, it was on the under side of the glass. Now, the streak is very visible esp in natural lighting. Its not noticable at night, because the screen light shines through it making it invisible.
It looks like dust? But im not 100% sure, but it has a directional pattern which leads me to believe its being causes by the inner fans of the system, and that there are some gaps where the air flow is constant. Also, the streak is in the upper left hand corner mostly (no where on the bottom poritions). Im assuming that the place holder at the top-backside of the iMac, for the exhaust fans to expell the heat from within, is what is causing this air flow.
Pulled my coveted 12" 1.5 ghz powerbook out of its bag and it's has an annoying little opaque stripe about 3/4" along the right side of the display. It changes color from yellow to green. When I pinch the lower side of my display together, it goes back to the blue background color, but still has a distortion to it.
The new 27-inch iMac uses up to 365W vs 280W for the old 24-inch! (going by Apple's published max. power consumption numbers. I doubt they would lie because it isn't exactly favourable for them to put in falsely high numbers in an environmental report).
That means there's some extra beef behind the extra components. Perhaps the ATI 4670 is a bit overclocked and the 4850 runs a bit faster than the old iMacs? Admittedly that 2.8 GHz i7 is going to suck a fair bit of power - the recent 2.8 GHz i7 860 model runs at a 95W TDP, however, the quad core iMac isn't available until November. So it won't be using the i7 860, and my guess it is using another custom processor, something a bit more power efficient, somewhere in between the 55W TDP of the old iMacs and the 95W TDP of the i7 860.
The difference between the power consumption of the two computers is 85W. The old iMac had a 24-watt digital amplifier, this new one has two 17-watt amplifiers. That brings the delta down to 75W. Say the iMac's i7 processor has an 80W TDP. That now brings the delta down to 50W. The new display likely wouldn't increase power consumption because of the LED backlight.
I'm not sure if I'm missing much (OK, two extra RAM chips may use another few watts), but there is still a fairly massive 50W unaccounted for.
This is perplexing me: I've only had my iMac 21.5" for a week. I posted here about the white screen issue after the 1st s/w update. Now, on every restart I get the same *but only when* my USB ext HDD is plugged in; unplug it & it starts fine, plug HDD in and it mounts, checked external HDD with disk utility - AOK. Never had this problem with my old 20" iMac! It's still in DoA period so is it best to get it swapped out?
I ran software update and got (iPhoto, itunes, Security patch) so I ran it and downloaded everything except the Intel Security Patch. So I restarted and decided to try again. Restart didn't work as it got stuck and I had to reach around and restart by holding down the power button. When it came back up, I got the white screen with the grey apple logo and the spinning clock like icon..... spinning and that is where I am stuck, left it off all night and tried it in the morning, same thing.
I did try:
-resetting pram (nothing happened) -restart in safe mode, holding down shift key (nothing, stuck on screen)
I would try to start up from the OSX disk except I have a DVD in the machine. I am thinking it was that security update that didn't download fully that is doing this but how do I get the imac, "unstuck"? or how do I manually eject that DVD to put in a OSX start up disk?
Three times in the last week or so my iMac's screen has just turned white (once with almost a ribbed pattern with thin grey vertical stripes evenly interspersed) and become completely unresponsive, with the only option being a hard reset. It's happened under a variety of conditions: while surfing in Safari, while working in Aperture, and once without doing anything (I was on the phone sitting by my computer). Each time I've restarted it everything seems to work fine for a couple days, but then it happens again. I've never seen anything like this and I figured after the third time it's time to ask for help. Does anyone have any ideas?
This happened many months ago but my imac evetnually started. Today I have tried several times to start my imac and can't get beyond the white screen.I get the mac sound at when it is trying to start up but then freezes at the white screen.
I just bought a very expensive Mac box, wide-screen flat monitor, printer, you name it, and I need SOFTWARE! I have searched the trial-ware sites, and many of the types of programs I need say "WINDOWS ONLY", or, "NO MAC VERSION AVAILABLE". Is there a place/site that specializes in Mac software that I do not see?
I have a problem with system wide shortcuts. I have managed to do the following: A shortcut for Lock Screen in the key chain menu in menubar. link to picture: http://twitpic.com/qs5wm/full but that shortcut just wont work?
Hello everyone, I'm currently looking to buy a 27 inch imac and can't decide whether to get a base i3 27 inch or a refurbished i5 quad core 27 inch. With the i3 I can get the student discount and qualify for the ipod, but the i5 is 23% off right now. Which should I get? Also is there a benefit of getting a 5 series graphics card over a 4 series graphics card?
I bought my Imac at the beginning of '06 and it's been great but today a small white line appeared running vertically all the way down the screen and over the dock and menu bar. it's white during boot up and then yellow after everything is loaded..does anybody have an idea what this is or how to fix it?
I have a Mac 10.4 (I would check but I can't get on my computer) had been running slow As I can see, many other Mac users have encountered the same problem that I now have: the dreaded �blue screen of death�. About a week ago, any internet browser that I tried to open (Safari, Camino) would freeze after loading its home page, and tell me that the application was not responding. After force quitting and restarting each program a couple of times, with no positive response, I decided to restart my computer to see if that would do the trick. Upon booting up, it then started the same sequence that it is still doing now: first a grey screen will briefly show, then a white screen with the apple logo and a turning dial beneath it.
Then my computer would go to a blue screen with a turning dial under it, where it would freeze and just keep showing the turning dial. So I looked everywhere to try to find a solution. I came up with this
"OK, restart your computer, hold down Command-s and type in the following:...............
For some reason, a friend of mine is having issues with her new iMac (one generation back). Here is what she emailed me about the situation:
Here�s what happens in greater detail. I quit or force quit all open applications. I press the ON/OFF button until the screen goes black. I wait several minutes and press the same button ON. I get the Apple cord sound and a blank white screen. The Apple icon does not come on; nothing happens. That�s when I close it down again and disconnect it from the back and reconnect it (a few seconds). Then I press the O/F button and the Apple cord sound AND the Apple icon come back, the system revs back up. All all is well � except for the ball coming back...
I was updating my iMac with mac os lion and it was installing the update when there was a power shortage and the iMac turned off. Now when I turn it on it won't get passed the white screen with the Apple logo and the turning thing, what should I do? The update I was doing was the Mac OS X Update Combined version 10.7.3
I have an iBook G4 which I want to use with a widescreen external display. I am not interested in gaming or doing anything fancy just surfing the web and working on documents and maybe looking at movies. I already have a hack that enables me to use a regular display which doesn't mirror the iBook screen. I just wondered whether I would encounter problems using a wide screen display and what the maximum resolution I should look for.
can anyone tell me why my screen on my imac is all white? the last time i use it was 6 months ago because i had to move. so i unplugged it and now i wanna use it again but when i turn it on, it's all just white on screen, i try to reinstall everything by using the disk but still nothing, can anyone tell me what's wrong with my computer?
i bought the 2009 refurbed 27"er and returned it 3 times due to yellow screen problem. for the 4th replacement they decided to send me the new model.
i have the 3rd and 4th replacements sitting here side by side.the 3rd replacement, which has a yellow corner is light years better than the new one. the new screen doesn't have yellow corners...it's a perfectly consistent yellowish brown tone. the older one has a yellow corner, but is much more illuminated and very balanced white. the max brightness of the new one is only 3/4s of the max of the old one.i tried configuring it to no avail.
are all the new models like this?it's quite a bit snappier, but the screen is worse than the last 3 that had yellow patches? it almost seems like it was a return and it shipped from cali rather than asia?
At work, we have a 17" G5 iMac from back before the iSight was put in. We're an Apple shop, so we have the new iMac actually on the floor for people to try out. The old G5 this thread is addressing is up on a shelf, but we want to turn it on as a display model. We plug a temporary mouse and keyboard into it, but the machine never gets past the white Apple screen with the "I'm thinking" animation. After a minute or two, the fan turns on full blast, but the white screen remains without any signs of moving on. What is our problem?
I own a 17" g5 imac and today I was just browsing on Firefox and all of a sudden the screen became checkered with thin pink and white lines. It is most noticeable on the menu bar and anything that is grey or white in color. It is not checkered on the blue background behind my desktop photo. I have an external monitor plugged in as well and the same thing is happening to that monitor.
I have a powerPC imac G5 OSX 10.5.8 1.5GB DDR RAM ATI Radeon 9600
Here is a screen shot: Haven't reformatted it yet. Hope there is a better solution. Purchased it used about a year ago. No warranty.
My brother got an iMac and yesterday he tried to install windows xp with boot camp. But unfortunately he made a mistake and the iMac shut down. Now the mac is stuck with a windows xp in it, and when he tries to start up the computer, it says "the start-up sound" and just stays with white screen. It sounds like the mac reads from the xp cd when it starts, but I can't get the cd out.I have looked everywhere and tried everything:
Hold down the primary mousebutton while it's starting, Hold down "fn" and the "eject" button while it's starting, and hold down "alt" while it's starting
I can't find any "pin-hole" to a paperclip or something.
