PowerBook G4 17-inch, display has vertical lines or fades to black

My screen fades to black or It will have verticals lines all over or a single horizontal line .. depending on its mode I guess, but I have to slightly wiggle or twist my screen and then it pops back to normal. Strange.
I have a larger monitor that I use with no problems and it serves as my backup now just incase my 17" screen connection completely drops.
What is the possible cause? I have NEVER dropped my laptop and I have been looking for things similiar on the board. Can anyone help me out?
One possible solution ... just sale it now and get the MacBook Pro.

What may have happened is the power inverter board to the LCD has gotten damaged or the cable to it has gotten damaged. http://www.dttservice.com/ I've found is relatively inexpensive at getting it fixed, if you can't convince AppleCare to cover it.

    king,
    If your Powerbook's serial number (do not post it here) starts with "W8" then the vertical lines are mostly likely due to a defect in the display itself. W8 is a factory code and, during the iMac G5 and PowerBook G4 timespan, that factory shipped thousands of units with the same defect. It cannot be fixed via software.
    As all PowerBooks are now classed as "obsolete," an Apple Store will not work on it. They will look at it ands tell you it has vertical lines and that they cannot fix it. This Apple article shows Apple devices they curently considered obsolete:
    Vintage and obsolete products - Apple Support
    It is possible that some Apple Authorized Service Providers (AASP) will still work on older computes but they cannot get neededparts from Apple. As this issue was so pervassive, it wil be hard for you or an AASP to find a used/pulled display that is not effected with the "W8 Curse."
    Although I love the old PowerBooks, I would not even spent the money for disks, much less the US$150-400 it would cost to replace the display, even should one be available.
    If you give us a rough idea of where you are in the world, we can suggest repair shops specializing in fixing older Mac notebooks, but be aware those resources may be rather scare outside North America.

  • Screen has vertical lines

    hi i have IMAC 17" INTEL DUO 1.83GHZ AND SCREEN HAS VERTICAL LINES WHAT MODEL OF SCREEN I USED MY EMC # 2104 THX

    Replacements 17" displays are around $750 and refrubished ones are around $550.

    Not to get your hopes up to high, but Apple had and may still have an extended warranty program for the displays in those Early Intel models. So personally, I'd call Apple Support first and ask if they are still offering an extended warranty program?
    Apple - Support - iMac - Service FAQ
    Sadly, another thing about repairing those Early iMac's? Is that there is no way of knowing if the display is the only problem and it could cost you more to fix it, than just buying a brand new 21.5" iMac. 

  • IMac 17" has vertical lines of multi colors

    Just bought a iMac 17" and it has vertical lines of multi colors. What are the causes, how can I troubleshoot the source and what is the most cost effective way to fix?

    Since the last 17" iMac was discontinued in 2007, it's unlikely that it's still under warranty, unless you managed to get Applecare with it.
    I had the same problem. The local Mac repair place, Dino computers in Pasadena, said that what it needs is a replacement display, but that alone costs $500, plus installation, so it isn't really worth it to fix.
    But I found a website call realmacmods.com, which offers a kit just for this purpose. Not for the layperson however. You can get a kit for about $50 and supply your own 17inch display, or you can buy a display plus adapter board for $150. I talked to Dino and they said they could install it for me for about $120. I decided to get some Mac tools and try it myself. The vendor recommends you have some laptop repair experience, which I don't have, but I have opened up desktop computers before, and that helped. Anyway, it worked. And, you get a higher resolution display: 1900 x 1200, formerly 1440 x 900. It looks great. But again, not for the layperson.

  • IPhone 5 has vertical lines on the screen. Help !

    Hey a few days ago. I left my phone on a table faced down in a small puddle of bubble mix. ugh.
    Everything works the sound, touch screen, camera. No glitches. But my phone is discolored & has vertical lines.
    I was wondering of If should just get a new screen or if there's a better way ??

    Try backing up the phone and then do a restore, when you restore set it up as new to see if it still persists if it does you''ll probably need a repair.

  • IPhone went bad after software update - iPhone 5 is now stuck on Itunes connect and has vertical lines

    iPhone went bad after software update - iPhone 5 is now stuck on Itunes connect and has vertical lines.
    I found a video on youtube with similar issues - http://youtu.be/Xuuqxx18-bA
    EVERYTHING HAS BEEN TRIED: Restore, Reboot, Recycle, Replacing Cables, etc....
    I don't have Apple Care, what to do? Spend more money and buy a new phone?

    Here is another person who has a problem with the iPhone 5 screen https://www.youtube.com/watch?v=sc1ZPWSA8dc and they have just received them NEW!!!!!
    I myself, two days ago purchased a  2nd hand iPhone 5 that was advertised as having a line of squares at the bottom of the screen. I Googled it and found people saying it was a screen issue and to replace the screen, so I did this and it is still happening with a new screen.
    I am starting to dislike Apple intensely after reading forum posts and watching videos where people are asking for help and telling us about issues that they are having with their phones.
    Why is Apple getting it so wrong with their updates and manufacturing that they are completely destroying iPhones that cost a lot of money and then expecting the owner to purchase another phone unless they are still in warranty.
    Apple you should be going out of your way to put things right for people but instead there is a wall of silence over so many of the issues destroying peoples phones.
    SHAME ON YOU!

  • My mac pro screen has vertical lines... How much does it cost to get it fixed?

    My mac pro screen has vertical lines... How much does it cost to get it fixed?

    When you fail to give information on the exact model MBP that you have, how do you expect anyone to provide you with any specific information?
    I suggest that you go to the iFixit.com and Powerbookmedic.com and look for parts and prices.  That naturally assumes that you know what parts are defective and need to be replaced.
    Ciao.

  • TS3824 My 2006 iMac has vertical lines that wont disappear - can this be fixed?

    My 2006 model iMac has vertical lines on the monitor that won't go away and are growing more all the time. Can this be fixed? I was told about the iMac Graphics Firmware Update but it doesn't work on my model - seems to be from 2011 models. Any suggestions?

    Hello,
    Have you blown the dust out lately?
    Get Temperature Monitor to see if it's heat related...
    http://www.macupdate.com/info.php/id/12381/temperature-monitor
    Take a screen shot & view that in Preview, move the Preview window around, if you see double lines it's a Video card/VRAM problem, if the lines do not move moving the pic around then it's the LCD or cable.

  • PowerBook G4 17-inch Display

    My PowerBook G4 17-inch display screen cracked. does anyone know where i can purchase just the screen?

    You can buy them on eBay brand new and/or used.
    No other companies I know of sell just the screen. They sell the screen but also it's part of their service package such as a screen replacement service.
    Apple of course, does not sell parts to customers, such as an LCD screen.
    There is however, one company I know of that says they sell Apple-compatible screens since Apple does not make their own screens, but gets them from OEM suppliers, to which they in turn get theirs.
    And I just found it, after looking for it on the web. Here they are:

    ** Make sure it is the right screen for your model, wherever you do get it. If you opt for a screen replacement service, they will get it right for you. But if you opt to buy it from someone who sells it by itself, make sure it is compatible and the right one. For instance, don't get a high-res screen if yours doesn't have one to begin with. You won't be able to use it because of the video card in your machine. Same vice versa... don't get a low-res screen if yours is a high-res one.

  • My ipod screen is white with small vertical lines with one big black line in the middle

    My ipod's screen turned white and had a few thin vertical lines and 1 thick black line in the center. the ipod can still play music but i have to randomly press the icons by memory to play music since I cannot figure out where the icons are. It all started after downloading a free app. I was browsing my ipod when the screen turned white. I already restored it to its original settings. I don't remember dropping my ipod. Help!

    Since restoring the iPod to factory defaults/new iPod did not solve the problem it appears that you have a hardware problem.  I would make an appointment at the Genius Bar of an Apple store.

  • Qosmio G10 has vertical lines on the display

    I've got a G10 which I've been using quite happily for the last 15 months since I bought it.
    However, it's now got 4 vertical lines on the display, 2 purple (magenta?), 1 yellow and 1 cyan. Other than these lines there are no other problems, it's never crashed or anything like that.
    The lines are always there, they never change in any way and are always in the same place. They appear on the display at very first powerup, before the Qosmio logo comes on.
    They didn't all appear at the same time, they have all appeared individually over the last two months. I did see the last one disappear briefly, then stay on.
    I'm assuming my display is slowly dying, which I would assume to be an expensive item.
    Any advice thrown my way would be much appreciated!
    I took a picture of the screen which you can find at:
    http://www.imagebucket.net/images/lldata/displaylines.jpg
    Note: picture was taken with Media Player fullscreen on a black image, just to show up the lines clearly)

    Hi
    I would suggest connecting an external display to check if it's a graphic card or a display problem. If this lines appears also on the external display so there could be also something wrong with the graphic card.
    If these lines don't appear on the external monitor so only the notebook display has a malfunction.
    However, this doesn't change anything on your situation. I would recommend contacting the Toshiba ASP for solving this issue.

  • My display has vertical colored lines then gray. What should I do?

    My MacBook doesn't start up correctly. When the power is turned on, several thin rainbow colored vertical lines appear on the screen then the whole screen fades to white/gray. What do I need to do to remedy this?

    HellO:
    Take it in for diagnosis and service.  The problem appears to be hardware.

  • Unibody Macbook Pro 17inch Display problems, vertical lines and artifacting

    Hey everybody
    I bought my 17inch MBP at B&H in June (week before WWDC, D'oh) and it was working fine until I came over to Ireland to work on a editing job for the summer, as soon as I attached it via mini display to a second monitor I started getting artifacts and vertical lines in certain shades and colours on the macbooks display, its gradually gotten worse so much so in fact that it is nearly unusable.
    I have seen the thread about the firmware update, but my computer is already up to date with that but it still has this problem, I contacted apple and was told to take it to the apple store and the genius bar in Belfast, as helpful as the rep was he told me it would be two weeks for a repair, by replacing the logic board. Which I just can't do as I've only got three weeks left on the job and need my mac every day. I've searched and it seems no-one is having this problem except me since the firmware update, but clearly my machine still has problems.
    Never had a problem with all my previous Mac's but I'm close to tossing this in the bin please help because if I can't get this solved I will have to move to PC and install my copy of AVID on it as this is the only other available computers at this production company.
    What to do? Has anyone else had this problem recently? Or know of a fix for it? I've tried everything downloaded the firmware told me its already installed, switched the graphics displays etc etc
    Please help
    Thanks

    Welcome to Apple Discussions!
    It sounds like there is a hardware problem of some sort with the graphics chips, and the only real fix is going to be to replace the logic board. So at some point, you will have to send your Mac off for repair.
    In the US, you can sometimes arrange to get a loaner. You might ask if this would be possible where you are, since the repair is going to take so long.
    Unfortunately, I don't know of anything that would fix your problem other than a repair.
    Good luck!
