T61 blue cast screen problem

A number of users have reported a blue cast screen problem. I have managed to correct this by altering the colors in color correction (reducing blue), but I have to repeat the correction each time I boot up. Is there a way to permanently save the correction so that it will apply with each reboot?

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.

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

Bright blue cast causing problems when adjusting blacks on RAW files

Just recently, I'm seeing bright blue in the darkest areas of my RAW images when working in Elements 8. It's very distracting, as you can imagine. Of course, when I adjust the blacks with the Alt key and the slider it just gets worse. If I complete the adjustments to the RAW file, save it as a PSD and then open it in the regular Elements workspace, the bright blue colors disappear and the photo looks normal. Any idea what might be causing this and how do I fix it?

Thank you to a fellow photog who answered my question via Facebook! Apparently one of my assistants mistakenly made adjustments in the Libray tab to the "Saved Prest" which saved her settings as "Custom" as well as saved the Whitebalance change she made there and the Tone Control section. I hit the "reset all" button under Tone Control and all is right with the world again! WHEW!

IMac G5 Graphic Card Replacement for blue screen problem

When I turn on iMac, I only see blue screen, the apple technician said Need to replace graphic card, Nvidia Gforce 7600GT 256.
1, can it install in IMac? Seem like it work for PC?
2, I had blue screen problem several time, I think I turn on iMac too long, so it burn out graphic card.
3, I have 2007 G5 24" screen model, is any durable and afford graphic card you recommend?
Where to buy for cheaper price?
Do I need to change mother board?
4, can I replace it by myself? Any picture or video for graphic card replacement?
Thank you.

If you look around, you might be able to find someone who will replace just the chip on the graphics card, which is what usually fails. It will take someone highly skilled; they really have to know what they're doing--it's not an ordinary soldering job.
Here's someone who found a non-Apple service to do this, and it proved to be far less expensive than a full logic board replacement. But I think this was in the UK.

Very slight blue cast on epson r1900 when match print color check box is checked

Ok, so this problem has been bugging me for some time now and I know other people have it too, because I can see it some of the screen shots.
I am running CS3 and and epson r1900. Using the latest drivers, and latest ICM epson paper profiles downloaded again just yesterday. So what happen is when I go to print a photo, whenever I check the match print color box, the proof instantly assume a very light blue cast which prints on the paper as well.
Let me tell you what I know it is not.
1. It is not double color management- ICM is disabled on the epson print manager side
2. It is not a badly calibrate monitor, My spyder 2 is working just fine.
I am wondering if its some type of gamut compression inherint the the ICC profile, but if that were the case, if I converted my photo into the icc's color space, it just take on the blue cast, but it does not it. The blue cast appears only after the match printer colors check box is checked. Even if I add additional whitespace to the picture, that what space, which when you think about it, should just be paper white, get printed again with the light blue cast. In checking and unchecking that above mentioned box, I can see that other features within the photo are being affected or shifted as well. If I use a different icc profile, say, the Kodak Professional Paper profile or a red river paper profile, there is no Blue Cast period when the box is check or unchecked, so it seems to be something related to epson profiles, and Photoshop.
I have removed the printer and reinstalled with all the latested drivers available at epson website, as well as removed all my old epson paper iCC profiles and reinstalled them from that latest available from epson as well.
I can see on some epson printing tutorials avaiable on the web, this blue cast in the screen shots. Like here- http://www.gballard.net/psd/printing_epson_photoshop_cs3.html
compare the the preview print area , the the white in the in input box for print size and you can see there is a cast.
So is this normal?
thanks
Patrick

Patrick,
ICC profiles include white point information. When you check the match print color box, Photoshop trys to show a quick soft proof of your image there in the print dialog. The blue cast is Photoshop trying to simulate the white point in the profile - which happens to be the shade of the paper. Some papers have more of a pronounced blue or yellow shade, and this shows up in the soft proof.
In reality you will not see nearly the level of shift on a print as you do in the Photoshop print dialog. That soft proof is not really super accurate.
To summarize it is indeed the paper ICC profile that is causing the effect. Different profiles will all show slightly different variations in the white point under these circumstances.

Blue cast to display

My black MacBook display is showing everything as if through a blue filter. Also, since updating iTunes this weekend, I find that when I log in it takes a much longer time to show my desktop preferences - it shows the generic blue swirl background before mine appears.
The computer was not restarted after the installation but if anyone has any suggestions about the blue cast to my screen today, I'd be very grateful. Thanks!

Thank you for the suggestion. I checked the settings but couldn't see that anything has changed. However I did do a simple restart and it sorted out both problems - clearly something wasn't connecting with something the way it should!

Blue Checkered Screen after using the Recovery Disks

I have a Compaq Presario SR2034NX XP Media Center computer. I followed the instructions and installed all the recovery disks. The screen then said to remove all disks and that it's going to reboot several times to finish the installation. During this process I got a blue checkered screen. I'm not sure what to do at this point. I took a picture of what the screen looks like and I'm enclosing a link to the picture here.

Thank you for your help and time!

I run into the same problem with fresh installation of W7 Pro on T530 with 1TB samsung disk.
This solution worked for me:
    Running check for updates will trigger this error message:
“Windows Update cannot currently check for updates, because the service is not running. You may need to restart your computer.”
Solution:
1.    Go to Administrative Tools/Services, and stop the Windows Update service.
2.    Then go to the folder c: /Windows/SoftwareDistribution and delete all of the files and folders.
3.    Then go back to Services and restart the Windows Update service which will recreate all of those folders again.
4.    Then manually run the Update Service and everything should work.

Screen Problems with iMac G5 20" (iSight)

Hello!
I had the same problem with my iMac G5 20" (iSight) as described by Bob North Apr. 18, 2006 at http://www.macintouch.com/readerreports/imacg5/topic2276.html#apr25:
"""" I repair Apple products, and recently I've seen strange and erratic display problems with the G5 flat-panel (iSight) 17" and 20"...and I am very curious about the origin. The picture will display what I will call "plaid pixles". Upon boot, the dispaly appears normal, but within 5-10 minutes, either at desktop or in ASD, the normal display will "crash" to the "plaid" display. The desktop, or whatever, can still be distinguished in the background, but it is overwashed by the plaid patterns -- which do change slightly, and also cover the full space of the screen. I've seen different scenarios, 3 in 2 weeks, where the symptom is exhibited with no particular failure pattern -- both before and after repair. I've replaced the main logic on one occasion, with no fix...but the 2nd try replaced both display panel and inverter. The display issue was fixed, but the system exhibited lockups only when it reached the destop. Another repair the same issue was seen after replacing the 20" main logic, where the symptom was not present previous. Personal opinion of the late 2005 IMAC flat-panels, in the hardware sense, is the likelihood of component manufacture issues, possibly the main logic boards or the panel displays themselves. Repair of this model, as opposed to the earlier, non-iSight flat-panel 17 and 20" models are extremely difficult -- access to main componenets is blocked by the display panel, which must be removed for each troubleshooting attempt. The internal hardware design is not oriented for repair ease...they are by far the most difficult to work on.
Any input regarding the display issues? Thanks.""""
I can't use the mouse or anything else, and after a while the fans start to go on max. This is the second time I encounter this problem within 30 days. What I have noticed is that the day before, the brightness of the screen started to "blink" slightly -- like if the screen tried to adjust itself.
But I haven't experienced what Bob North describes as the: "Upon boot, the dispaly appears normal, but within 5-10 minutes, either at desktop or in ASD, the normal display will "crash" to the "plaid" display".
I just restart with the power button and everything is working OK. I made an Extended Hardware test without any problems detected.

Does it look anything like this?

My nearly 3 year old Titanium PowerBook G4 just did this one day, out of the blue. The problem went away after a few minutes, but I had already taken photos. Thanks to those photos, Apple gave the powerbook a new logic board.
(This PowerBook has had its logic board replaced twice, a new optical drive, and a cracked case edge replaced. AppleCare has more than paid for itself. Despite the occasional problems, I remain very happy with this machine. I'm sure I'd be much less happy if I had not bought AppleCare!)

Copy displays in blue on screen

I am using Adobe Acrobat Professional 8. All my copy (all text) displays in blue on screen, when it's supposed to be black. When I send to printer however it prints correctly in black. Is there a reason whey this is happenening and is there a way to fix this problem? I have tried opening different pdfs from multiple sources so it's not just one pdf file that is doing this. This is happening to all the pdfs not just the one that I have created. When I open on a different computer or if I open the file in Acrobat Reader, copy is displayed in black like it should be. I am on a MAC running 10.6.8. Thx!

Satellite L500-1XD constantly restarting & displaying blue recovery screen

I bought a Toshiba Satellite L500-1XD laptop from an Argos store in August. Soon after I got it it occasionally restarted itself and displayed the blue recovery screen saying the laptop has recovered from a hardware failure. This has become more frequent recently and it often shuts down, displays blue screen, restarts and does this over and over again.
I have not installed many new programmes on the laptop and have installed all updates. I have removed any programmes I did install with the exception of Microsoft Office.
Another thing that might be related if that when the laptop starts up it says the Toshiba Service Station has stopped working and tries to check for a solution to the problem.
I would any appreciate any advice on how I could perhaps remedy this
Thanks in anticipation

Hi katrina_1,
That means the preinstalled Windows version is still installed, right?!
Well, I think its hard to say why it happens It could be a software or hardware malfunction. Both could be possible.
The most reasons for blue screens are drivers or hardware itself Are all devices installed properly in device manager or do you see yellow exclamation marks?
In your case I would try to reinstall Windows. Maybe its only a software or driver issue
Furthermore if you have installed two RAM modules, test it with one module only. You can also use Memtest86 or another RAM diagnostic tool to test the RAM modules for failures.

Sudden macbook pro screen problem after genius bar "repair"

I took my 15" early 2011 MBP (still under 3 year applecare) to the genius bar after I discovered the battery had swollen up and was pushing the trackpad up. They replaced this and I also asked them to reapply the thermal paste as I felt like it was running hot causing the fans to increase with relatively little load (apparently there was a problem with the early 2001 MBPs and thermal paste which is well documented elsewhere). Machine worked great when they handed it back to me in the store.
But when I turned it on a couple of days later, serious problems! First there was a messed up blue / grey / purple / green screen with lines all over it & it didn't boot. I felt like the DVD-drive noise it usually gives sounded lower pitched than usual too but I could be imagining that.. I turned it on & off several times and each time a similar (but slightly different) screen. I tried various different "startup key" combinations eg safe boot, hardware test without success.
However after I reset the NVRAM I got just a grey screen which then booted into snow leopard. It could've been a coincidence that this happened after the NVRAM reset, I don't know. Anyway, the mac is sort of working - great!
BUT the screen colours are still messed up. Looks like what I'd imagine you'd get if you tried to run in 16 colours. There's also some flickering near the bottom of the screen. Weirdly though, when I click and hold on some items, eg in the dock, the colours seem more normal again on parts of the screen.
Examples below:
1. colours look terrible here!
2. the blue triangle isn't right at all. (note the curvy lines are just an artifact from the camera)
3. however when I click there is is some improvement to some of the colours on bits of the screen eg the dock items (except the logic icon which still looks wrong) - I don't think the big circle in the middle is right (that's not a flash, it's on the screen).
I've tried to run the hardware test by holding down D on start up and aside from taking longer to boot, I don't get any options to run tests.
Anyone have any idea what could be causing this?? As the colours are correct sometimes, I'm inclined to think it's a video card problem rather than a screen problem. System profiler says I have and AMD Radeon HD 6490M & Intel HD 3000. I'm just wondering if they could've somehow damaged the video card when reapplying the thermal paste. But I really don't know.
I will book another genius bar appointment but there's a 1 week wait and it's kind of annoying!
Thanks.

There's no recall for early 2011 machines - only for mid-2010 models.
But you're right - there's a growing thread here of hose having problems with the early 2011 GPU. Odd that it doesn't seem to affect those with late 2011 models.

PB Mercury (400 Mhz) Screen Problem or Why is my screen green?

I replaced my screen due to the fact that is was cracked. After I reassembled it I was faced with a screen that was blueish-green and severely washed out. This is uniform thru-out the whole screen.
Suspecting a bad lcd cable, I disassembled and replaced the lcd cable and I still have the same results.
Any ideas?
I have reset the PRAM and the NVRAM numerous times without fixing the problem. When I hook up an external monitor it shows a good picture and I can see that the desktop is showing up on the lcd, but it is so washed out that it is difficult to make out the lighter colors.
Thanks,

Powerbook Titanium G4 400 Mercury Mac OS X (10.3.9)

Hi Steve
I had the same problem on Tuesday. The blue/green screen disappeared when hooked up to another monitor but returned on restart. I tried several things but eventually gave up and contacted Apple. They suggested a few things which I hadn't tried but to no avail.
One thing they did suggest though that it could be a software and not a hardware problem and if all else fails I should zap the hard drive. So that's what I did and the problem's gone. Although the archive and restore did not cure it. It needed a good old erase. But I guess you could try archive and restore first.
I hope this helps.

Pavilion p6157c freezes at blue hp screen HELP

My desktop freezes at the blue hp screen on startup, any button I press that is shown on the screen (f10, esc, f9, f11) won't register or do anything. I am running windows 7 and have a pavilion p6157c desktop. This is very important to me and if anyone helps I will be greatful!!

Hello Bruddahshark,
I understand you state your computer will not bypass the blue HP screen, is that correct? I will be happy to help you.
Try turning the computer on and tap the F10 key immediately, and see if you are able to access the setup menu. When doing so the F10 key is sometimes very sensitive so if it fails the first time try it at least 2 more times.
If you are successful, toggle down to one of the drives you see below. One drive will be for your hard drive and the other will be for the DVD drive. Select the drive that does not mention DVD-RW. Once you have selected on the drive, select smart support, and then Smart Shot Test. The Short Test will last about 3-5 minutes, if that test passes then select Smart Extended test, now that test will take some time.
See the screenshot below for an example of what the screen should look like.
Please respond back at your earliest convenience.
Thanks
