Powerbook 17" display issues: posterization and other psychedelia

Hello,
My Powerbook 17" has, since it's purchase in June 2005, a problem with the display that occurs periodically whereby the display suddenly posterizes and becomes extremely hard to read. I have found that adjusting the display angle, that is, moving the Powerbook display hinge can make it worse or can cause it to revert to normal. It seems to me that there is a short in or interference with the wiring that must pass through this junction. Has anyone else had a similar experience with their Powerbook 17"?

Your PowerBook is the same generation as the one most people are complaining about, although the majority of affected users that have been reporting the problem have machines that were manufactured around the end of the first quarter of 2005 at the factory described as W8 in Shanghi. There are ways to find out if yours is one of these machines by doing some web searching. Stating site names here my go against Apple's usage policies for this discussion board ... sorry, but info is easy to find with a little searching.
I am glad to hear that you have not as yet experienced the dreaded lines or blanked-out areas. It is still a good idea to call Apple Care and get a case number if you have not already. Explain your problem and they may be able to help. Even if there is nothing they can do, your problem will be registered. This case number may come in handy if heaven forbid your machine starts developing more severe screen problems. Good luck!

    The utility has had less and less useful information .. it might be time to simply find a different utility.

  • Why some PDF docs displayed are garbled and others are not?

    I've had this love hate relationship with adobe for the past few days.  I'm so frustrated since I can't seem to figure why other pdf docs display information correctly while others are garbled. It looks as if the letters/text overlap.  I 'm loosing sleep over this.  I'm at my wits end. Can someone please help? I appreciate any assistance you can provide.
    Thanks,
    C

    Hi Allegria11,
    Don't lose sleep over Adobe! Let's see what we can figure out. But I have lots of questions to get us started:
    Are you creating the PDFs yourself, or viewing PDFs from different sources?
    What are you using to view the PDFs (Reader, Acrobat, and what versions)?
    Do these PDFs all use the same fonts, or different ones?
    Do you know whether the fonts are embedded/subsetted in the PDFs? (You can check by choosing File > Properties and clicking the Fonts tab.
    Let's start there, and we will dig deeper if none of these shed any light on the problem.
    Best,

  • Tags, no longer displaying file names and other issues

    I upgraded to Mavericks, MacBook Air.
    I need help sorting out what is going on with Tags.
    I have a screen shot, but uploading it to this post is another problem I have run into with Mavericks.  I click on the camera icon, click on upload file, and then I get a list of greyed out files, and am unable to select any of them.  Very unmac like.
    Back to the tag issue.  The tags are listed in the open finder window.  Most of the tags I have created, when selected, will display all the files with that tag, and show the file name or icon.
    BUT, one of my tags, which has over a thousand files, will not display the file names.  What is shown are a list of blank icons, and no file names.  The preview for each file still shows as it should when a file is selected, and the file name is listed in the preview.
    A picture is worth a thousand words, so I really wish I could have uploaded the screen shot!
    In addition, some of the files, e.g. a .pdf file, will show no icon, no file name, no file size, but will open when double clicked and dispaly the file name and a greyed out addition to the file name "-Locked".  Much weirdness.
    Tags have not been working well for me.  I have used colours extensively in the past for organization and now it seems to be a huge problem converting to tags.  What a painful transition from Mountain Lion!

    With the backup completed, I followed your suggestion:
    "Go to your Finder "Go" menu hold the option key and choose Library. Then go to Preferences folder and trash these files:
    com.apple.finder.plist
    com.apple.sidebarlists.plist
    Then, restart, or log out and in again."
    The smart folders disappeared.  The original Tags named by colour are back on the list of Tags, and the problems remain unchanged.
    In the Tags I created for my file collection, call it the LotsOfFiles folder, there are no file names listed, none.
    However, when I changed the permissions on every file in the LotsOfFiles folder to Staff-Read & Write, then I was able to change, add, and delete Tags from the files.  Also, once the permissions were changed the file names appeared, after five minutes... so I edited this entry when I discovered the change.
    The files in LotsOfFiles have been collected since 1995, and have been saved to many computers and many backup systems.  They also have been used, saved, changed etc. in operating systems dating back to OS7, and almost every operating system up to 10.9.  They also are being used on different computers right now, one running OS 10.3.9. one running 10.7, and one running 10.9.  The computers all have different admin logins and info.
    But I still can't upload files to this forum!

  • Powerbook G3 Display Issue

    Dear Forum Mac Guru's,
    I know this has been asked a few times before but I thought all the comments I've read so far have not been quite my situation. So here I go...
    I was wondering if you are able to help
    diagnose a problem I am having with my Pismo Powerbook?
    The LCD still has a good crisp colour to it with no dead pixels or dim
    spots or bright spots. That is until things start to go wrong. If I leave
    the powerbook off and turn it back on again the LCD is fine for a while.
    Then it will start to flicker with horizontal white lines in random places
    every time. The image that was last on the display freezes and eventually
    the flikering lines will become solid and the white will wash away any
    image that had previously been there. eventually this white will go a dull
    grey colour. This will all happen very quickly. In a matter of about 30
    seconds.
    Initially it was only intermitant and would go away by pressing the back
    of the screen or pushing down on the screen (down dosen't help all that often). This however rarely helps these days.
    I initially thought it was the Inverter board but then came to the
    conclusion it might be the display cable. After replacing the display
    cable (making sure it was the same brand screen) it still started to
    flicker and the same things happens.
    I have been running an external display for the past year with this problem and the external display runs without an issue. When the laptop display gose blank the external display runs perfectly.
    I did a number of test on the computer when the display gose funny. I tried to push pod and poke the main body of the computer but this has no affect on the problem at all. The backlight is not an issue, it remains on. The screen has a number of vertical lines that appear once its grey (these may be there straight away but don't become apparent until the screen is greyish). I have leff the screen in the greyish state for a while and generally a couple of white lines will remain and randomly flicker every now and again. The screen in this state sometimes seems to dim in light intensity, this comes in and out. If the machine has been off for a little while (off not sleep) then the screen generally will last alot longer before going to the bad state. Moving the screen from almost closed to almost open the screen can go to the faded state at any position but will generally change as the screen is moved. The screen is best I feel when the screen is in the full extension open. When the screen dims (properly whilst saving power) it dims correctly but just makes the greyish look darker. If i touch the screen in the right spot it will spring back to life and be as crisp as it ever was. It also seems to have a darker rectangle in the centre of the greyish area. I think that is all?
    Other than this problem recently the computers battery died and has been replaced and the cd/dvd drive has been replced. The screen problem was happening before these became and issue though.
    Would you have any ideas? Also any suggestions on parts to fix it with?
    Thanks in Advance, Tre.

    In terms of heat I'm not sure.
    It isn't only one spot that you can push to get it to come back. I have to manipulate the screen carefully in a number of different combinations. Also if the screen brightness is down the and screen fully open with an external monitor on the screen can sometimes clear up even after 4 hours plus of use. If I then move the screen up it will take a few minutes to go bad again. Even if the brightness is left down.
    I actually have a spare screen from an old 400mhz model which is identical brand. Its just not in as good condition and has to bright spots in the corners and one dull area middle bottom. Its just not in as good nic as the current one when its working. Is there a way to 'tighten' the LCD in case its a pressure problem or is still a heat issue?
    Many Thanks, Tre.

  • Ps4 display issue black and white screen

    Hi,
    So to cut it short I was watching TV fine before. PS4 was fine when I switched it off last night.I turn it on this morning to no colour in the picture. I've checked the TV settings, switched all hdmi related. Reset in safe mode display and default settings changed the HDMI lead even switched TV same issue.
    I'm starting to think it's definitely a machine issue. I hope it's something simple because it's barely over a year old.
    Help please someone

    Didnt need to go through the Initialisation, Simply disconnected the power of ps4 and Bravia Tv and connected them back on after 10 Mins. Temporarily lost hdcp features but probably thats why it worked. 

  • Weird problems with motion 3 displaying pink lines and other garbage

    I am using Motion3 to create HD graphics. With each of my projects I start with motion everything is fine until I build about 4 different layers or add any type of motion or filters.
    It seems as my projects get more complex my viewer window or canvas starts displaying weird things. Pink lines, white and black garbage, nasty thin lines, various other junk. Sometimes the image is completely gone.
    I have had some luck retrieving it by turning off motion blur or turning of field rendering and turning it back on. This fix only works sometimes.
    Other times my video displays fine until I render out and then the garbage happens.
    Anyone come across this?
    I am currently using a an ati radeon 9600 video card and it's running two monitors on dvi and one vga. I have ordered an nvidia 7800 gs in hopes it will fix this problem and ease the pain of render times.
    I have been using motion 2 for a while and never had this issue. I was hoping to milk this system for a while before having to upgrade.
    Any thoughts or suggestions?

    I think you are pushing that card to it's limit with HD and splitting the VRAM across two monitors. I would bet a new card will clear things up.

  • 17-inch PowerBook G4 Display Issues

    Hello Everyone!
    I'm just posting to voice my concern about the issues with the vertical lines on 17-inch PowerBook G4s. I have a 1.67Ghz PBG4 17 and it was the model right before the last one, it had only a 1440x990 resolution, I want to know if this is involved in the problem or not but I do have one stuck pixel one the right side center of the screen and that has been there almost sense the day I bought it but I didn't notice for a wile and when I did it was too late to do anything about it and I hope that we can get through to apple with our problems and they will provide a replacement because I know that most of you with this problem have it a lot worse than I do.

    Your PowerBook is the same generation as the one most people are complaining about, although the majority of affected users that have been reporting the problem have machines that were manufactured around the end of the first quarter of 2005 at the factory described as W8 in Shanghi. There are ways to find out if yours is one of these machines by doing some web searching.

  • Display issues with languages other than English (also related: slide results not reporting to LMS)

    Running: Captivate 6
    I'm having two
     issues that I thought was only tied to Cyrillic characters, but appears to be with multiple languages (confirmed with Brazillian Portugese, Latin American Spanish, Swedish and Russian). 
    1. Quiz Pass/Fail result message appearing truncated (top and bottom of message is cut off, or message appears wrapped and overlaps)
    I've attempted converting the text to a UTF-8 format and tried that as well, but had no success.
    2. We have a 108 slide test created in Captivate v6; the English version pushes all 108 slide results to our LMS without issue. When we created the version in Russian, one slide refused to push slide results.
    Steps to confirm/resolve:
    I've confirmed the settings are identical on the project and on the slide between both the EN and RU versions
    I've pasted the russian text into the working EN project and published/tested and that particular slide does not push results to the LMS (the only thing changed was the text on the existing slide)
    I've tried duplicating working slides and replacing text; it fails to report
    I've tried converting the text to a UTF-8 format and replacing the text; again it fails to push slide results to our LMS
    I've tried about every option I can to get the RU version fo the test working (pushing results for all 108 slides); Out of desperation I've created a work around which is putting the question and answer options in as images (not text) and then the test pushes all 108 slide results. This leads me to believe that the issue is regarding how the font is viewed/read by Captivate 6 and ultimately reported to our LMS (SABA).
    I've reached out to our localization company (SDL) and their only suggestion was the UTF-8 formatting (which failed).
    Please help! Thanks!!

  • No Screen Display (but LED and other functions fine)

    My phone is working - I can hear the alarm when a text message comes in, the phone rings and I can answer it by sliding up.
    I can connect to my PC via USB by plugging it in and touching on the screen in the area where I know the corresponding button is.  But nothing is showing up on the screen.  It's illuminated, but just a blank black screen.
    I took it to Sprint and they said I could buy a new Pre for $550.  Is there no other option for repair here?
    I'm very disappointed that I had to go back to my Treo 700p, as I was absolutely loving the Pre.
    Any assistance would be greatly appreciated! 
    Post relates to: Pre p100eww (Sprint)

    I have had my screen freeze on me at least once a week in the last month, often twice.  I get a blank screen, even when charging on the touchstone. I can accept calls and receive notifications of text messages and emails but the screen is completely blank.
    I have had to remove the battery and restart the phone to get it working again.  So far this has fixed it everytime but it can certainly be annoying as the boot up time is long.  Has anyone else experienced this?  Is this a known hardware/software issue?  I have not found any other posts on this subject.

  • Displaying "Top N and Other" in Pie Chart

    Hello All,
    As the subject implies, we are trying to display in pie charr top 5 products by sales and bucket rest of the product sales in "Others". Oracle provided documentation gives below code. But I am not sure as how we can package this in view which can be used in chart

    Edited by: 948378 on Sep 5, 2012 9:46 AM

    Hi, 
    For your first question, Other should show up if you have more than 10 groups generated.  Looking at the Group Tree, how many groups show up? 
    What happens if you did a Top5 instead of 10?  Does Other show in the Group Tree? 
    For your second question, Crystal will group on unique values regardless if the group is on a field or formula.  I have a sneaking suspicion there is either a leading or trailing space in the name.  Use the Trim function to remove the white spaces like: 
    IF (IsNull({Command.AcctPriKey}) or length(ToText({Command.AcctPriKey}))<1)
    then Trim ({Command.custname})
    else Trim ({NAcct_.Nacct});
    For your third question, throw the iif format out.  That was introduced because of dBase years ago and most people I know hate using it.  Go with the traditional.  Easier to read and figure out. 
    Good luck,
    Brian

  • My opinion on scratching issues, Camera and other hardware related glitches on iPhone 5

    Been a cell phone enthusiast, technician so I dumped the Nokia N97 phone in 2010 for Blackberry bold and in 2012 had a first touch of iPhone 4S- I thought this device was beautiful, perfectly designed and finished. Oh what a great piece of art, I’m hooked!
    Shortly after getting the iPhone 4S, iPhone 5 was launched so I decided why wait 2 years before getting iPhone 5, so I decided to send money to my brother overseas to get me an unlocked iPhone 5 even with all the uncertainties with LTE networks, service provider etc.
    At first, my brother thought I was insane to fork out that amount of money to get a phone? Usually money gets sent from Europe and America to Africa and not the other way around, I guess he will never understand why, it’s an iPhone dear brother.
    While my order is in “Processing state” I read in the news about the design flaw reported, i.e. the decision to use Aluminum because its lighter, So it happened that the anodization of the Aluminum casing is not properly applied to protect this gorgeous device, these things happen but  why is Apple not halting production and really fixing this issue?
    Why I am so disgusted is that, Apple is enforcing strict controls at assembly line that would be Foxconn as reports have it but does that prevent the phone from easily scratching after a user buys one? The quality control has now slowed down the production of iPhone 5 and I’m not sure anymore if I will get my iPhone 5 at the expected date.
    I don’t get this really; Apple enforces quality controls to make sure no scratches on these iPhone 5s during assembly knowing that when a user buys it, it can easily get scratched.
    I am very disappointed in Apple and the current CEO is somehow a failure, I speak under correction but Steve Jobs would have handled this situation more professionally.
    Another infuriating response from Apple about purple haze in pictures taking with iPhone 5 where Apple openly informs us to cover the camera before taking a picture- This is ridiculous!
    Apple will not be the first to make a technology mess, every major manufacturer or technologist have had their share of design flaw, Toyota recently recalled some of its cars, I think Apple should man-up and fix this crap.
    And for the record, I am no Samsung fan, some of you might come up with weird responses insinuating I am a Samsung fan, naturally I hate Samsung phones, I am an IT specialist and I have worked on mobile phone repairs in the past and Samsung are just too fragile, I’m talking from the days of Nokia 3210 and the likes.
    What are your views comrades?
    Regards
    Babajide Agbebiyi

    The only people who can possibly assist you with this is Apple Customer Relations, call your local Apple contact number and ask for Customer Relations then explain your situation clearly and politely (be firm but don't rant).
    You might want to investiage what the local laws are regarding defective goods and 'fit for use' definitions on warranties etc. Consumer Protection can be a useful tool to use or bargain with if needed ...

    Hello popp09,
    The issue sounds more like a problem related to your Graphic driver. Could you please make sure your "graphic driver" is update to date?You should also make sure you've applied all Windows Updates in your OS.

  • Qosmio F30-117 - Display issues - red and green lines

    Hi there,
    I have a qosmio F30-117 and up to recently, I was delighted with everything about it.
    Then, mid session, the graphics began to deteriorate, which a reboot fixed.
    Then a few days later, it did it again and this time when I rebooted it came up with a corrupted display, lots of aa's all over the place then lines of red and green all over.
    Managed to get in by selecting safe mode with networking and got a desktop although still with the red and green lines all over it.
    Now its gotten worse still, when I boot up the laptop screen itself is blank, its getting something because it isnt totally black like it is when its powered off, but its blank.
    As a check I connected an external monitor and managed to get in again to safe mode with networking, but its still very bad, and still has the red and green lines all over.
    I started to have a look around on the good old www and there are numerous posters and articles with problems, and lots mentioning the red and green lines etc...
    so Im not alone, but no-one seems to know exactly what it is.
    Some have mentioned Toshiba acknowledging this as a problem and doing repairs even if out of warranty.
    So, any ideas, any advice, and does anyone know if Tosh have indeed accepted the problem and offering any help??
    Thanks in advance

    Hi
    I think it's a common problem in the Qosmio F30 models. After long term use, the soldering balls under the GPU chipset start to melt down because of the over heat and the bad soldering quality that was used with the F30 model that cannot resist high temperature. Now you have to replace the motherboard, since the GPU is build within the motherboard.
    However, there is another two solution for this problem and cost less money amount:
    1- do what is called a "heat reflow" for the VGA chipset: to do this you have to take the motherboard out and heat the VGA chipset on the motherboard with a heat gun or you can bake it in the oven for a few minutes at low temp, this will make the soldering balls melt and go back to there right position. However, you need to keep in mind that this solution is temporary and will last maybe for month then you have to do it again and again till you ruin the GPU and then the only solution will be to buy another motherboard. So I don't recommend that you do that at all, but if you don't want to spend a lot of money on a new motherboard this will help you to recover your data, even though there is more easier solution to do the recovery.
    Anyways, you can go to youtube and search the term "VGA heat reflow " to see how people do it.
    2- send your motherboard to a repairing service that can do what is called reballing: what they do is that they will replace the soldering balls under the VGA chipset with new ones that can resist high temp. and this solution is permanent and even in the future you don't have to worry that the same problem will happen again since the new soldering balls can take high temp change. I do recommend this solution even more than buying a motherboard, since the motherboard that you will get will generate the same problem after few years.
    you can find this type of repair service online if you googled the term "VGA reball repair" or you can find it on ebay
    If you decided to replace the motherboard I think you will not be able to find a new one, and in case you found one it will be more expensive than a new laptop, but still you can find used motherboard for your qosmio on ebay or online. so you need to do a search and find out what fits your budget or maybe it's better to buy a new laptop.
    Sorry about your qosmio, and hope that my post will help you!
