Successful 15" screen replacement (Line Issue)

After purchasing a BTO PowerBook G4 15.2 1.67 DL, I quickly noticed the now well-known “white lines” issue. Initially, I called AppleCare, and sent my PB in for a depot-repair (with a copy of the “crankycat image” AND a copy of http://www.cameraid.com/art/quadrants.gif (found in this thread http://discussions.apple.com/thread.jspa?threadID=280560&tstart=45) . A week later, I received my PB with a note indicating “ Unable to duplicate issue). I then took my PB to my local Apple Store, and had one of their technicians look at it. After seeing the “Quadrants” image on my PB and looking at it on a 17” display model, the technician agree to take my PB in for repair. Today, I picked up my PB, thinking there was no way it would be repaired. However, the new screen DOES NOT display the line issue). To re-cap, I initially had a PB WITH the “line issue”, and now the same machine, with a new display, DOES NOT have the line issue. I really did not want to purchase the 17”, and was a bit apprehensive about purchasing one of the new MacBook Pro’s (I’ll wait until the 2nd Gen), so I am completely thrilled to now have a display w/o the line problem. So, I can confirm there are “line-less” 15” displays out there, from having seen both first hand.
Thank You Apple Care...

48K,
Yes, I'm Sure. I checked with the "crankycat" and the "quadrants" images. It was pretty noticeable on my original screen, particularly if I dragged the images vertically one pixel at a time (esp. the quadrants). Just to make sure, I double checked the images on the display 15" models (each of which DOES have the "lines problem." On the new screen, the top two "quadrants" DO NOT shift at all, and the colors are identical. The bottom two "quadrants are slightly darker than the top two, but this also appears to be the case on EVERY screen I have tested (including the CRT on my Mac-Mini). Like I said, the top two do not shift at all (previously, the shades of grey DID shift).
There are NO LINE at all doing the F11 "trick" on the new screen, but the old screen DID have the lines.
I pressed the "Detect Display" button in Display Preferences, and made sure to choose "Color LCD." Note: it still has a magenta caste, but not as bad as the previous screen.
Unfortunately, I didn't get a lot of time to talk to the tech (they were pretty busy). So, I don't have an answer to your question about a new batch of displays. I do know, they did replace the screen, and did NOT replace the logic board.
My machine was in repair for about a week.
I have owned this machine for slightly over a month. So, I was past the 14 day return policy.
I DO have AppleCare (That Helped).

  • I have a 17" Macbook pro with flickering red and cyan(blue) lines across the screen. The issue disappears temporarily when I tap on the computer, and the problem does not occur when I use external display or try to screen capture the problem.

    I purchased my Macbook (17") through a certified apple tecnition in August 2012, it was refurbished and the motherboard was completely replaced. I do a lot of photo editing, but I have been unable to do so because of the red vibrating lines that interrupt my screen. The issue disappears temporarily when I tap on the computer, and the problem does not occur when I use external display or try to screen capture the problem. I brought the computer back to the technition I purchased it from and he said that it was a problem with my fan, so I have two new fans but the issue is still occuring. He says he doesnt know whats wrong. Does anyone have any information on this issue?
    Here is an image of the issue

    I recommend having your Mac serviced by someone competent. A force sufficient to "blow apart" the fans was clearly excessive and may have damaged the display cable, as well as any number of other problems.
    Dust is properly cleaned with a vacuum, preferably one designed for computer service, and they are not cheap.
    Compressed air should never be used. It just blows dust everywhere, often into places where it can no longer be removed.

  • Thick black line through iPad 1- will screen replacement work?

    There is a 2 inch black line through the width of my iPad 1. iPad is out if warranty and apple genius told me the only fix would be to buy another one. Could I fix this issue through replacing the LCD screen? Any suggestions would help.

    Might. Might not. Could be part of the backlight is bad. Could be the equivalent of the graphics card is bad.
    Dunno how much your screen replacement is but you may want to weigh that cost against it not working and you paying and still not having a functioning device.

  • Screen has lines running through it, is it worth replacing screen?

    Screen has lines funning through it, is it worth replacing screen on 2009 iMac?

    What do you mean by lines running through it?  There have been users with vertical lines, sometimes blue, or yellow, or pink, or combinations.  Those have all turned out to be a bad graphics unit chip that the Apple store techs were able to remove and replace without replacing the entire logic board.
    Take it to an Apple store genius bar and have the techs test and advise on how to resolve this.

  • MBP screen replacement issue

    Hello,
    I just replaced my glossy screen on the MBP with Matte screen. Everything went fine except I have this issue now. I double checked every connection and they all seem fine. The boot up screen looks fine, so I know that the screen is not defective. I tried searching but I didn't find anything. From what I read so far, it should just be an simple direct swap.
    Anyidea?
    Thanks in advance for help.

    As this is a fairly routine job there should be no difficulty getting the parts and the time to do it is reasonably quick. For cost contact the nearest Apple service centre. It's listed on their computers and will normally be a standard Apple rate.
    I had a screen replaced under warranty in Africa in an earlier model and there it was only the supply which was slow.

  • HT5455 Is It normal that my premium category 15" retina MBPs screen has ghosting issues, then I get declined from screen replacement?

    Is It normal that my premium category 15" retina MBPs screen has ghosting issues, and I get declined from screen replacement?
    I have purchased this hardware in Budapest for approximately 3000 usd. I was a bit shocked to see screen ghosting after a few days of use. The problem was getting worse but because I am a design consultant working mainly on my Mac I couldnt take a week off to leave It at an Apple service station.
    Last week I was surprised to receive the information from the local Apple repair shop in Germany that my retina MBP that I bought 13 months ago was declined from screen replacement by Apple.
    Considering the price of the product I find It unacceptable that I need to work on a defective product and see shadows every time I leave an Illustrator or InDesign window open for a short period of time.
    Is there any way to resolve this issue? I wouldnt like to pay another 800 dollars just to replace a component on my defective Apple product.

    Contact Apple Support directly.  In Germany the Expresslane or this number
    0800 6645 451 will allow you to speak directly to someone from Apple.    Explain your situation.   Mind you, AppleCare and issues with Apple products like this have to occur without any user accidents or user installed parts to ensure that Apple will cover you.  If there was a user accident or installed part, you may be turned down.  If you have the original Apple parts, and did the installation yourself, replace it with the original parts very carefully following the directions on http://www.ifixit.com/ unless you can afford an authorized service provider to do it for you.  Since we don't speak for Apple here, being end users like yourself, that's why I say "may", as I've seen Apple handle these things on a case by case basis.  So hopefully you don't have any obvious damage that looks like it is user caused.   Good luck!

  • Why is my Macbook Pro suddenly and constantly shutting down/crashing on me and giving me a blacked out or blued out screen with lines?  Seems like a total system failure is happening?

    Macbook Pro- shortly after upgrading to free software upgrade to Mavericks- 10.9.5-
    has suddenly been freezing up, but went more directly to 'shutting down,'  CRASHING on its own.  Most of the time, if I'm even able to successfully get the laptop turned back on, it only stays up/on for a few moments before repeating the failure.   The failure is often accompanied with the monitor going 'blank,' or most typically either 'blacking out,' or going blue/green or grey screen with lines or grids all over the monitor.  All Desktop visibility, functions or applications in process disappears.  This has caused repetetive 'forced shut downs,' which I never usually do, unless prompted to because I have no choice like this.... Or as I said, the computer itself will just shut down and turn off by itself.... Can anyone tell me what this issue is, and I'm pretty sure other Mac users have seen this exact thing I'm describing happening on their laptops, with their systems or on their monitors.  Someone please explain or point me in the right direction... as naturally my laptop just went out of warranty as well.... And I don't know if this means the entire system is basically corrupted, dying/dead... and or if it is a monitor issue, a hardware issue, software issue or if there is anything that can be done to restore, repair it, etc.?   Also another thing I have noticed ever since getting this laptop- (few years old now...) is that it runs VERY HOT... has in fact burned my lap /skin many times... and seems like the fan or internal operating systems/functions are also perhaps not functioning properly.  Can this also be causing the problem?  Or is it a corruption or virus of some kind? etc.   Thank you.

    What you describe sounds like a hardware issue. Unfortunately, you'll need to get that checked out by Apple. If you have an Apple Store near you, make an appointment with the Genius Bar and take the machine in for evaluation.

  • Sent my PB in for horizontal line issue repair.......but.........

    Just got back from the apple store and showed a genius my display and to my surprise he said he could see the issue at the upper half of the of the screen. I tried to show him the crankycat image but he said there was no need.
    I then told hime that the part needed to be used for replacement according to other sufferers is the 646-0324 DSPL, 15.2, WXGA++,SAMSUNG,Q16C part but he said apple don't use that part number here (i live in london). i then ask if the display will be replaced anyway....he says yes.
    When i get the repair sheet, i dont see anything mentioning display replacement, all i see is a "Flat Rate Repair Charge, PowerBook G4 15"-£170" and Labor Charge, PowerBook G4 15" - £100".
    These don't sound really promising. I then request that they test the replacement display with the crankycat image and he goes."everything will be tested properly before despatch dont worry"
    From what i gather the guy just wanted to rush and get things outta the way so he could go home.
    I really don't think this will get fixed, but lets hope apple proves me wrong this once.

    Update- line issue has been fixed

  • HT4061 I had my front screen replaced. Now nothing shows up on the screen, as if the phone was turned off. Help, please.

    I had my front screen replaced. Now nothing shows up on the screen, as if the phone was turned off. Help, please.

    Replaced where?  If it was done by anyone other than Apple the warranty has been voided.
    Regardless, the screen replacement was obviously not successful.  Take the device back to whomever replaced the screen and address the issue with them.

  • IMac LCD screen replaced, Blue Screen startup

    Hi there, I just had the LCD screen replaced on my late 2007 Aluminum iMac today (due to a permanent red vertical streak) by an Applecare certified technician. He did a meticulous job with the replacement, and the iMac booted up just fine afterwards. About an hour later, though, I tried starting up the iMac and after the grey screen with the Apple logo it gets stuck on a blue screen with a constantly spinning pinwheel.
    Now I tried everything, booting up in Safe Mode, Single User Mode, resetting the PRAM, FSCK, Disk Utility using Disk Repair, unplugging the power cord for 30 seconds, etc. and nothing seems to work. It just gets stuck on a blue screen whenever it tries to boot up.
    Just wanted to see if there is anything else I could try out before I give Apple a call tomorrow, if this boot up problem is a result of the new LCD screen replacement or what? Any help or insight in the matter would be greatly appreciated, thanks.
    Update: I should note that right now I'm in the (lengthy) process of restoring from a Time Machine save to see if that helps out in any way.

    You could try the following first, but a repair may be required.
    iMac G5: Fails to startup (From an article at MacFixit)
    Some users are reporting an issue where iMac G5s fail to properly startup -- apparently at a hardware level -- never reaching the Mac OS X startup splash screen (Apple logo with a spinning progress indicator).
    Note that in cases where the system does reach the Mac OS X startup splash screen or further progression but stalls, software issues may be to blame.
    Potential fixes
    Disconnect external devices External devices -- especially those that draw power from the system -- can cause issues with startup that manifest either at the beginning of or later in the boot process. Try temporarily any external FireWire or USB devices then re-attempt startup and check for persistence of the issue.
    Reset SMU Although this workaround was not successful in Connors' case, resetting the iMac G5's SMU (system management unit) as described in Apple Knowledge Base article #301733 can resolve a variety of power-related problems, including sudden-onset startup failure.
    Check power cables Check your power cord for a loose connection. As noted in the aforementioned reader case, unplugging and re-plugging the power cord can sometimes result in a successful startup -- likely the result of a more snug fit.
    Also, power cables can become defective or ship in such a state.
    Try exchanging the power cable from a problematic machine with a system that starts up properly to eliminate this as a potential cause.

  • MacBook Pro Freezing After Screen Replacement

    I recently took my MBP in to get the screen replaced due to a screen separation issue. When I got it back it froze every now and then, but it kept continuing. Everytime I restart the computer after a freeze it will freeze up sooner and sooner. At first I thought it was a RAM issue since it particularly did it while watching videos, so I bought new RAM and it continued to freeze. Tested the new and the old RAM, but they were fine. I took it to the Genius Bar and the guy said it was a failing harddrive. Got a new harddrive upgraded to Lion and it is still freezing. I asked if something could have gone wrong when the screen was replaced and he assured me no and even if something had gone wrong they wouldn't cover it unless the actual screen was broken.
    If I leave the computer off for a day it will take about 30 min before the 1st freeze, then after restart about 15 min, then 10 min, then 5 min until it will only log in then freeze.
    Any guesses as to what could be causing the freezing and if it would be worth fixing as this MBP needs a new battery, a new drive (since the drive is on loan), and has the flickering screen issue?

    Screen Replaced Jan 8, 2012

    Thanks for the reply. As an update, I took it into the Apple store again and it froze while they were trying to run the test. This time the guy said it was covered by the repair warrenty. After 2 weeks without a computer because something was wrong with the graphics cards they called me back and said they were just going to give me a late 2011 mid-range MBP. So I currently have a brand new MBP with no issues
    Yeah... 3.5 years and they just release that fix for flickering screens. I hope it works for everyone. I know some people had some major issues with it.

  • Iphone won't power on after screen replacement

    So I've dropped my Iphone 4S once and screen showed blue vertical lines. I replaced the screen for about $120. After 6 months or so I dropped it again and the screen cracked. I decided to replace the screen on my own so I got a new one and replaced it, but the phone doesn't power on after the screen replacement. I plugged it on charger, did a hard reset but still nothing. I plugged it on pc and it was recognized by the itunes! As it was plugged on pc, I did a reboot again and it left itunes as if it was powered on and suddenly powered off. Still plugged in I tried to power it on again, it was recognized again by the itunes but the screen still wasn't working. Another thing is that it burns a lot without even being on charger or on pc, and I need to take the battery off.

    Sorry. There's not much we can suggest. Apple won't touch that phone now.
    Try looking for advice someplace like ifixit.com.

  • Mac Pro Retina Screen Replacement Procedure

    So I love my Mac Pro Retina but it has the ghosting issue, everything else is fine as far as I can tell with it, its had a few kernal panics but they have all been graphics related while Chrome was open, and only in Mac OSX, so I am assuming thats fine. I can play any game I want in Windows 7 with out trouble so thats a w/e.
    I am past the 14 day mark for just turning it in for a new one, and I wouldn't want too anyway. So I was wondering how they handled pure screen replacements, if they do them there at the store, or if they have to ship it off. If anyone has any experience with this any info would be helpful.

    I want to know what Apple has offered other people so I can go in and negotiate knowing what solutions they are offering. I have had Apple loose equipment for a period of time after being shiped of for repairs, so if they tell me its going to need to be shiped off, and someone here has had an instore replacement of the screen I would like to be able to point to that so I don't risk having my laptop lost in the ether again.
    PS Apple actually handled it well by replacing the piece of equipment with the newest model, so the lost equipment ended well for me that time, but it was kind of a gaint pain in the butt.

  • IMac 17' screen - has lines and is freezing help!

    I have a IMac 17' - My screen has lines across it and sometimes a triangle- If for some reason I'm able to get it to work past the users choice screen, it freezes within mins. Does anyone know how to fix or what the issue might be?

    It's probably a bad video card or bad caps (the little soda cans) which are either swollen or leaking.  If your machine isn't an iSight, take the back off and inspect the caps.
