Green/purple screens

I am a teacher in an elementary school and I maintain a couple computer labs of 20 iMacs, OS 9.2. About 4 of the computers have developed green or purple tints on the screens. Everything works fine (programs and all) but the screens are horribly green or purple tinted. They periodically flash to normal colors for a few seconds, but then back to the green/purple tints. I have tried recalibrating the color sync and adjusting the monitor colors but it doesn't affect the green or purple screens any. Are they dying soldiers? Is there anything else I can try?

Yes, dying soliders
Since you said OS9 I'm assuming these are G3's
If they are 233/266/333 models and you are comfortable removing a couple of screws and pulling the sled, the VGA cable is easily accessible, you could try unplugging and reseating that. 350 and later is similar but a couple more screws to get in there.
It's worth the 5-10 minutes or so it will take to get in there, beyond that it is really not economical to repair those. Replacements can be found for less than the costs of repair.

Picture Included. Mid 2012 13 inch Macbook Pro green/purple lines on screen. Freezes. Sometimes 3 beeps.

Alright I have a Mid 2012 13 inch Macbook Pro purchased in June 2012. For about the last month, I have this issue where as I am using it random colored lines will show up on the screen (lines usually green, purple, but occasionally the issue occurs while booting and lines are black on white background). As soon as the lines appear, everything freezes. Sometimes the computer automatically reboots. Other times, it will just turn off and start beeping 3 times in a row. AT first, I thought this may be a video card error because it happened a lot when I was watching videos. However, it also happens randomly when I am just using safari/chrome with no other programs runnings. The most annoying part of this issue is that it is completely random. Computer won't act up for maybe 2 days straight during all activities (videos, surfing the web, etc). Then I will have a day where the problem is consistent.
Also, although I think this is just a correlation, all problems started after upgrading to Yosemite.
Picture below:
Does anyone else with a Macbook Pro (especially 2012) have this issue? These two discussions seem to be describing this very situation:
Screen froze, purple lines, three beeps. Help!
Macbook Pro screen glitches, 3 beeps, NOT THE RAM

thanks alex. I'm going to the genius bar later this week for them to get a look at the issue.
in the meantime, do you have any idea why the problem occurs when I apply a little pressure to the bottom of the computer (under the command screen). here is a video of the situation: https://www.youtube.com/watch?v=88C34bHZAd8&feature=youtu.be
also, i found this thread describing my exact situation: Field of vertical lines all over Macbook Pro screen? (+ freezes, beeps)
do you have any idea of a solution from reading that?

Open your QuickTime control panel (either via the Control panels, or by going "Edit > Preferences > QuickTime Preferences" in the Quicktime Player). In the Advanced tab, uncheck Enable Direct3D video acceleration:

Firefox shows alternating green & purple lines in full screen mode on Facebook games,why?

Every time I click on the full screen option in my games on Facebook,I get green &purple lines filling up my computer screen instead of the game screen.Why is Firefox doing this?

You can try to disable the hardware acceleration in the Flash Player: [[Cannot view full screen Flash videos]]<br />

T61 pink/purple screen problem

Hi all,
Sorry if this problem has been posted before - I tried to look through the threads and couldn't find it.
I have a 14.1" T61, type 7662-CTO.
My screen will periodically suddenly get a pink or purple sheen - white areas look purple, while dark areas look green. The computer still functions and I can basically see what I'm doing, but it's just a little ugly to put it mildly.
After a while, the screen will revert to normal, but if I work for much longer, it becomes purple again.
Some things I've noticed:
1) When I use an external monitor, it works fine.
2) Positional changes sometimes cause the purple event, and sometimes positional changes relieve the purpleness.
3) When the screen turns purple, I can often put a lot of pressure on the plastic just under the Ctrl and Alt keys on either side (or both at the same time) and the screen will turn back to normal either while I'm putting the pressure on or sometimes for a little while afterwards as well. This prompted me to tighten all the screws I could see corresponding to that piece of plastic on the bottom. While this has decreased the frequency of purple screen events, they have not gone away entirely.
Research on the web has made me wonder if this could be a backlight problem (symptoms sounded similar, but not quite the same as what I've got), or a graphics card connection problem. However I'm definitely not sure.
My computer is no longer on warranty and I do not have much experience tinkering with laptops, though I am willing to try if I can get the right parts and get good, detailed instructions.
Thanks for your help!
Evan

This sounds to me like your green signal to your LCD is not correct - maybe it's sitting at a constant 50%.
My guess is that the ribbon cable that carries the LVDS signal from your mainboard to LCD has come a bit loose, or has developed a crack. You might try shifting the cable around a bit, or carefully reseating it in the ZIF connector if you are comfortable disassembling your laptop (and voiding the warranty).
Alternately, the crack could have developed inside the G84 chip itself - if the rumors are true, this could be one of the outcomes of the G84's defective manufacturing.

IPhone 4 screen flickering then turning off and when i try to turn it back on it either works or I get a white or purple screen. When i turn it off it doesn't turn back one

Ok so this started around a week ago. I got home one afternoon put my phone down went back to it and pressed the home button and it seemed that it turned itself off so I tried turning back on, didn't work so I hooked it up to my laptop tried turning it on again it came on but I got a WHITE screen. So after that I decided to leave it for a bit I went to it after it started working fine...until 4 days later. I was on instagram and all of a sudden the screen starts flickering like crazy and then it turned itself off, I did what i did last time and just left it for a bit it came back on working fine. And then about 2 days ago I was listening to music and the screen froze then started flickering (getting quite annoyed at this stage) and then turned off, this time I tried turning it back on straight away only this time it worked. And that brings us to this morning, i was on facebook and about 5 minutes later it starts flickering and freezing once again and then turned itself off. So i hooked it up to my laptop I then got it to turn on for like 6 seconds then the screen started to dim and turned off. That brings us up to now about 10 minutes ago i tried turning it on, it turned on but I got a PURPLE screen and it just stayed like that until i turned it off. Does anybody have any idea what is going on? I think its the screen itself but i'm probably wrong. All help is appreciated.

I am also having the same problem.. Its too much annoying and its unfortunate nobody at apple support has anyclue of what is happening?
... This is happening almost most of the time keeping my phone down most of the times.

N8/C7 PURPLE SCREEN ISSUE AND HOW TO SPOT IF YOU H...

MODS THIS IS NOT A POLL OR IN ANYWAY SHAPE OR FORM A VOTING THREAD IT IS A THREAD TO WARN USERS ABOUT THE PURPLE SCREEN ISSUE AND HOW TO SPOT IT IN THEIR PHONES CLEAR AS DAY , I HAVE BEEN INFORMED FROM THE DIRECTOR OF COMUNICATIONS AT NOKIA VIA TWITTER THAT THIS THREAD IS OK AND THE TEST IMAGE IS FINE TO LOAD UP
The following has been added by vandelay (Nokia administrator) :
Please note that there is normally a slight variation in the purple color level in each display
unit. This is related to the display manufacturer's optical tuning process. However, some Nokia C7 and Nokia N8 users seem to be experiencing a
slightly higher level of purple color tint on their device screens.
Nokia Care's technical experts told me that the easiest way to spot this problem is to just look at the black idle screen of the device - if there is a clear purple color tint on the idle screen, you should have the device inspected at a Nokia Care point. They will repair the device the device under warranty if there is a clear defect in the device.
So seeing some purple on the test image does not necessarily mean that your screen is faulty, but we hope that it helps some people to decide whether they should visit a Nokia Care point.
(end of vandelay's addition)
as you may or may not have read many n8s and c7s have a purple tint issue
this can easily be spoted by saving the picture below to your pc , transfering it to your n8/c7 , then viewing the image in your gallery
if the image shows purple squares in some areas then iam afraid you have one of the screens that is showing defects in gradiation of colurs and the greyscale
there are also many n8s out in the wild that dont have this problem , i have 3 n8s , my gfriend has one , hers is perfect and shows the test image with no purple tint at all my three n8s all have purple tint and some display it worse then others
the test image can be viewed on any brightness and it should display just as it does on your monitor screen ,my gfriends n8 displays the image perfect under all brightness levels yet my three n8s show the purple tint heavily on low brightness and not as much on full brightness
the test image can also be viewed via tv out and hdmi out and again if you have a defect screen you will see the image perfect on your tv yet on your n8 screen you will have purple tints
here is the test image for you to load to your device and view via the gallery
as stated above if you have one of the screens with defects in colour gradiation you will see some of the squares as purple
this shouldnt be happending as there n8s out there that display the test image perfectly
from all my research on this in the last month and my time studying ICT systems support in which i have a diploma , it seems clear to me that nokia have used at least two screens in the build of the n8
many phones bought between october launch and december dont have the problem yet there are still some that do but not as many as now , phones bought from the end of december up untill current date seem to have the issue moreand its now nearly impossible to find one without the purple tint issue
this leads me to believe that from the start nokia were using at least two screen in the n8 , then one started to run out around december and by the end of december a huge majority of n8/c7 handsets have the troubles, if not all of them shipped after december
infact ive been to every phone shop in lakeside , chelmsford , colchester which included : carphone warehouse , o2 , vodafone , orange , three , phones4u , tmobile all n8/c7 handsets i asked to look at had the problem not one n8 i looked at didnt have the issue
i have been in contact with nokia care escalation team , all they did is send me very badly refurbed handsets back for my brand new n8s , which across all three handsets had the following faults
#hdmi covers scratched and worn
#no imei number under the hdmi cover on one of them
#torx screws on battery cover very worn
#plastic top caps not fitted right
#one had a huge gap between the silver screen surround and the main chasis of n8
#they all still had purple tint issue
so nokia sent me three refurbed handsets for my brand new n8s , i obvously complained as they were so new i could have taken them back to the shops with the reciept but now nokia had changed the imei numbers my reciept was useless , i said i should be sent three brand new n8s , they again sent me badly refurbed handsets just as bad as the 1st lot and again all three of them had purple screen issues
i complained again and this time supervsior took over the case and agreed that 3 new n8s should be sent to me as mine was so new , she got them sent out and this time they were new but they still have the purple screen issue
thats a toatal 12 n8s direct from nokia and all of them have had the issue so i cant recomend going to a nokia care point or nokia care uk as the refurbs i was sent was a complete joke and looked like they were just used handsets that had been through a rough time
through this month of me talking to nokia and sending emails and getting these phones swapped back to a condition of the phones that i sent them , they have said they are investigating it and taking it seriously however after some of their actions towards users (myself included) on these forums it doesnt seem like they are taking it very serious at all , they have known about it for a month now and we still have not had an offical response from nokia themselves

http://n8geeks.com/nokia-n8-amoled-display-issue/
there are many more threads about this issue across the net and if you google n8 screen problems or n8 purple screen problems you will come acroos many many pages of unhappy users from all across the globe
i just hope nokia sort this out soon
ho do you users with the problem feel about this issue and how do you think nokia should resolve it
id be happy for a screen swap at a nsc or via warranty postal repair as long as it could be done quickly and the user wasnt without their phone for too long after all this is nokias mistake and not the users that bought the phone so all fixes should be at minimal disturbance to them
heres hoping when you test the image your not as unlucky as me and many other n8 owners from across the globe , its a brilliant phone but this screen issue lets it down alot especially during watching films and stuff

sorry to hear you guys are having troubles too , its a shame sucha great device as the nokia n8 has had an issue like this arise , it is effecting alot of n8/c7 handsets and is quite a widespread issue across the globe
it would be great to hear from as many users as possible about this and what they think about it as a user of the c7/n8
jimmyireland about your post mate
yes it was written by me and yes it ws deleted not once but 3or4 times actually
the mods said it was because i had set up a poll and voting system , so i read through forum rules and posted it again with what fitted their guidelines and even put in big caps that it was not a poll but a thread to help users identify a problem and discuss it which is what the forum is for , it was deleted again , i then posted it again with just the test image and how to spot the problem and again put big caps that the post fitted their guidelines and was just to help users , it was again deleted and i was banned by mods for 2 days saying that i had broke forum rules and posted a poll and that the test image wasnt a proper test image
i then asked other users to post the image but when they tryed nokias spam filter kicked in with a message saying that their post contained spam and that they should write it again and try posting again
to be honest it really looked like they were trying to cover up the issue , fair enough my 1st post could be considered a very very rough poll but the posts i made afterwards were edited to fit nokias guidelines and they still removed them ad banned me and then other users posts were marked as spam
so i tweeted alot of people and even nokia have said that as long as the post doesnt contain polls/votes then it will be fine to postand that mods shouldnt delete it , which was excellent news and hopefull this thread will stay and users can load the image and test their screens and then discuss the issue here so nokia can see users discussion in one thread , it will alo help awareness of the issue
hence this post that isnt a poll but a thread to help users identify wether their n8/c7 has a screen with a defect in the gradiation of colours
as stated in original post not all n8s have this problem my gfriends doesnt and it displays the test image perfectly on all brightness settings , yet my n8s show the image as very purple on low brightness and the brighter the screen goes the less the purple is shown , it is still there just not as visible as it is in the lower brightness settings
as i also mentioned many n8s between october and mid december are fine although some still have the problem , yet from mid december till current date the amount of n8s with purple issue is much much higher and it now seems very very rare that you will get a brand new n8 from the shops without this screen issue which leads me to believe that from launch nokia have used at least two screens in the builds of the n8 , some great screens and then the ones with dodgy purple tint , from the threads across the web it seems like the good screens nokia were using either run out or they have failed to source the same screen or the manufactuer of the screen has changed something
iam not a nokia hater and iam not here to cause trouble or loose nokia sales etc
i love nokia have used them for years and used symbian since the 6680 , iam always helping users across the web with their nokia problems and am an avid user on nokia users please check my profile and feel free to check my posts and how many times ive been thanked for being helpfull
http://www.nokiausers.net/forum/members/buxz777.html
as you can see i love nokia and spend alot of time using their devices , speaking highly of them and helping their users with problems, i also love good customer services and customer relations
i understand that big companys have build issues iam a gadget lover and trained in ict supprt iam not silly and understand that these things happend and building these phones with such complicated electronics and some could end up with issues , it could happend to anyone , sony , apple , samsung , blackberry , lg etc etc
however its how the companys react to these issues and relate to their customers that have spent 100s of pounds on their devices that is important , issues do arise , its how the company looks after its customers thats important
i think alot of users think the same , they dont expect nokia to click their fingers and go heres a fix but they do expect nokia to investigate the issue and they do expect nokia to relate to its customers and not ignore them or the issue which is what it looks like when posts are deleted and users are banned for posting informative posts that help users identify a problem
things like sending users really bad refurbs for brand new n8s also dont help users confidence in nokia statement of going to nokia care about the problem as all i got was second hand looking n8s that still have the problem they were sent off with and the originals were in much better condition
like i say iam not here to cause trouble and i love nokia the n8 is the best phone ive ever had and its almost my dream device and everything ive wanted on a device for years its the ultimate convergance device and agadget lovers dream , however when you see your gfriends and some of your mates n8 screens display the test image perfect then your n8 display it with a very purple hue it does dissapoint you and you do hope that nokia will take notice and fix the issue with the least amunt of hassle to the users
cheers jimmy and sorry about the long post just wanted to clear some things up
now lets get back to discussing the issue and what other users think about it
have a great evening

IMac will not boot up/purple screen

Hello people,
We've got a newer 27" iMac bought in 2010. Anyhow, yesterday we experienced a power outage. We installed a surge protector on the house but it didn't do our iMac any good. The iMac will cut on but goes to a purple screen only showing the speechless box. We can't get it to do anything else besides moving the courser. Does anyone any ideas as to what is going on and how to correct it?
Thanks in advance for and help or advice,
Ray

Look in your owners manual, it has instructions on what to do if your machine doesn't boot.

Why is my mac book pro mid 2012 display green flickering screen?

Why is my mac book pro mid 2012 displays green flickering screen? I was able to return the screen back to normal after i turn the lid up and down.
Is this a hardware issue ? should i return to applestore since the warranty still valid?

It seems like your display is damaged. As your computer is in warranty, take your Mac to an Apple Store or reseller to get the display replaced for free, as it's in warranty

Hi. I cannot launch prem elements 9 any more. It gets so far, then just freezes on the purple screen

It is driving me mad! When you launch, it'll get to the "open project or "new project" window. If you press "open project" it just freezes after a while, if you go "new project" it will ask for a title then freeze on the blank purple screen. It used to work fine. I have tried uninstalling it and re-installing from the CD I bought but to no avail. What should I do?
Cheers
Adam

What computer operating system is your Premiere Elements 9 running on? Are you running the program from the 9.0.1 Update?
1. Make sure that you are set for Run As Administrator and running from User Account with Administrative Privileges; you have the latest version of QuickTIme installed on the computer with Premiere Elements 9.0/9.0.1; your video card/graphics card driver version is up to date according to the web of the manufacturer of the video card/graphics card.
2. If no help from "1", delete the settings file named Adobe Premiere Elements Prefs file. Assuming you are working with Windows 7, 8, or 8.1 64 bit
Local Disk C
Users
Owner
AppData
Roaming
Adobe
Premiere Elements
9.0
and in the 9.0 Folder is the Adobe Premiere Elements Prefs file that you delete. If that does not work, then delete the whole 9.0 Folder in which the Adobe Premiere Elements Prefs File exists. Make sure to be working with Folder Option Show Hidden Files, Folders, and Drives active so you can see the complete path cited.
3. If that does not work, the go for new installation files from the following web site and then install them inserting your purchased serial number
http://prodesigntools.com/photoshop-elements-9-premiere-elements-9-direct-download-links.h tml
It is critical that you read the "Note: Very Important Instructions" at that web site; otherwise, you will get an Access Denied message.
In general terms,
a. Is your computer optimized - ccleaner run through (regular and registry parts)
https://www.piriform.com/ccleaner
b. check for pile ups of preview files, conformed audio files, conformed video files?
Let us pause here while your review and consider the above.
Any questions, need clarification, do not hesitate to ask.

Purple screen on start up

Very strange thing happened within the hour. At one point my keyboard started to type characters in a different language. I shut down computer and restarted. When I restarted a purple screen appeared. To the lower left was a circular arrow. In the middle of the screen was an icon of my Macintosh HD with a small "x" in the corner, on the lower right was an arrow pointing to the right. At first, I couldn't press any of these icons as my cursor was doing the small timer thingy (not beachball). After a couple of minutes, my cursor became the usual mouse arrow. I clicked on the arrow pointing to the right and my computer went to the login screen. I've not yet shut it down and actually I'm afraid to. Anyone know why this might happen and if it is a sign of something wrong?
Thanks-
Dave

HI David,
Sounds like the hard drive needs help. Try booting from your install disk and check for errors.
Restart your Mac while holding down the C key, pressing the power button and inserting your install disk all at the same time. An Installer window will open, but do not proceed with any installations. Instead, from the Menu Bar, select Utilities/Disk Utility. In the Disk Utility window click First Aid, and then click Verify. If Disk Utility reports errors, click Repair. When Disk Utility is finished, from the Menu Bar, select Utilities/Startup Disk. Select MacintoshHD 10.x.x and click Restart.
Troubleshooting Startup and Login Items
If you can, see if you can locate a crash log.
How to locate a crash log:
1. Open Finder.
2. Click "Go" in the menu, then select "Go to Folder".
3. Copy and paste this path into the Finder dialog: ~/Library/Logs/CrashReporter/
4. Click the Go button.
5. Finder opens the folder containing the crash log. Look for a the crash file with a date field that looks like the most recent.

IPhone - purple screen and can't update or restore

Hi!
I can't find any post that answers my problem so hopefully someone can help as it's been really frustrating! This morning I got the purple screen asking for me to plug my iphone into iTunes (I have the option for emergency calls). I was running a valid beta of OS3.0 and hadn't had time to upgrade on the 17th. So I assume the beta had expired.
I plugged my iphone into my PC and sure enough, iTunes (8.2) told me I needed to upgrade as the version I was running had expired. So I clicked on update but iTunes tells me that I am running the current version and that no updates are available. I'm confused!! I thought I could perhaps restore the phone but it tells me a restore is not possible when I try it. So this leaves me stuck with an iPhone that won't work and iTunes that can't make up its mind if I have the right version of OS 3 or not.
Anyone shed any light or help with this?!
Thanks you

This has been sorted!
Spoke to Apple's very nice and patient Developer's team again. They gave me different advice this time and told me just to run through the steps here: http://support.apple.com/kb/HT1808
They had given me different advice before as, they said, some of the beta versions required additional steps and downloading of carrier files etc
