Question about Apple 15" PowerBook G4 Aluminum 1.67 GHz LCD Display (p/n 1002587) (661-3749 1002587) Mac Notebook

9 Answers

Screen problems I'm about to get a new MacBook Pro and would like to sell my PBG4. But the screen is acting up - sometimes completely black, but more often just the bottom 2/3 will either be black or keep the previous image frozen. The top third is usually okay, and with a little squeezing, the whole screen comes back to working condition. I don't want to sell my PB like this and would like to have a dealer fix the problem, but I don't have a lot of confidence in their getting it right at a reasonable cost - (about $100-$150). Otherwise, it's not worth selling - I don't think I can get more that $5-600 for it, right? Any ideas about how to advise the service dept. of the Apple dealer - they already told me "never heard of that problem", which didn't inspire a lot of confidence... Or is there a possibility of checking for a fix myself?

    expert Kevin said - video card is bad. If this is the case, why does the screen work well 95% of the time with a little squeezing. Isn't it more likely that some connections is loose?
    But if he's right, does anyone have an idea about how much a new video card will cost?


  • Hillel Weintraub Jul 21, 2008

    thanks for the various comments. I wonder if what I've described is a common problem with laptops that are moved around a lot. (not dropped though!)
    and if anyone has any other ideas about how I can approach a service department to avoid being overcharged.

    I did check the site recommended by one expert - www.MONISERV.com - but couldn't locate any advice for do-it-yourself repairs

  • Hillel Weintraub Jul 22, 2008

    this is such a wide area - so many causes and finding things out is not an easy thing unless you're really comfortable working on the inside of your mac. But there are people who have done it and were kind enought to document their work on the web.

If it is a loose connector and it would seem like it, you can open up the book and inspect the cables between the lcd and the motherboard. the vga itself is most likely not replaceable wihtout replaceing the motherboard.

If you're not afraid to tinker Here's How one guy took his apart.

Lots more good info at Power Book Medic

Once inside make sure all cables and connections are secure. These things seem to sometimes wiggle loose over time depending on how the laptop was used or handled.

Good Luck

Does not look a software fault , rather an hardware problem.
This is either a faulty video adapter, or a bad lcd ribbon cable, you do not get any job of this kind done on a laptop for less than $100. It takes $50 only to diagnose the problem, probably repair will be around $200.

As Abrsvcs pointed out, the graphics card is built into the motherboard. Most likely a cracked solder or faulty connector ribbon, that is best left to professionals to replace and diagnose. I do not think it is an LCD fault, or else you would just have a black screen.. My guess is a faulty ribbon connector. This shouldnt cost too much to replace, but I wouldnt recommend you doing this yourself..

    You could try the link at the right that says Repair Service. Just
    enter your Zip code in the box, and you will get a list of nearby
    service centers. Mention that you were referred by Fixya, and you might
    get a discount, but do shop around..:)

Greetings,

Video Card or LCD that's causing it. It's a hardware problem.

Problem with Mac's is all parts are proprietary.
You can have it repaired and get small amount from it or sell it very low price. Don't take the risk of getting it repaired cause you might end-up spending a fortune.

Keep us posted and thank you for using our service.
FixYa for all your troubleshooting needs.

If pressure returns the screen to full function, there is a connection problem. The issue is whether or not this can be fixed without replacing the panel. If you ned to replace the panel, the cost will be close to $300. There is no way to determine if the fix requries the panel without opening up the case and examining the ribbon cables and the panel connectors. It is possible that one of the cables has a hairline crack in it.

If you feel confident enough to open up the case, do so and examine all of the connections carefully under magnification. Be extremely careful when opening up the top that you don't rip the cable by accident as these cables are often taped to the panel.

Keep us posted.

    There is no "video card" in the laptop. The video "card" is part of the motherboard. What you have is a connection problem as I stated above. What I can't tell you is exactly where the break is. Follow the steps I outlined above.

If you've already tried turning up the brightness of the screen (the "sun" icon), then you may have a problem with the backlight (possibly burnt out, in which case you'd need a new backlight bulb). See this post for more details:

Which is the best laptop?


This is very subjective, but either the MacBook or MacBook Pro because the MacBook Air is more expensive than the Macbook because it is thinner, but does not outperform it.
Now between the MacBook and MacBook Pro there are so general guidelines: -If price doesn't matter, the MacBook pro is the best Apple laptop because of its RAM and Aluminum body finish, also its Sandy Bridge processors and its new Thunderbult Port.
If price does matter, than there are some general deciding factors:
  • What do you do? If you work on your MacBook pro using PhotoShop and Movie Editors and a lot of software- the MacBook Pro is what you want. Also if you game, the MacBook pro is awesome.
  • Is it just for fun? If you want this laptop just for recreational use and not for games requiring heavy processing power for graphics, just get the MacBook.
Bottom Line: MacBook Pro is the best Mac laptop

My macbook pro wont start and i can hear the noise of the starup but the screen is black


Connect to external monitor to isolate the problem. If you get a picture on external monitor, then you know your screen is fu.k.d up. Since its a MacBook Pro, it might still be under the 1 year warranty, so take it to the Apple store and have them deal with it. If you get no picture on the external monitor, then you know you got a problem with the computer.

Gray splotch on lcd screen on a macbook pro 13-inch


That is most likely a defect in the LCD itself... there was a huge issue with this on the older PowerBook series - like shown in this picture, 3 roughly dime-sized circles to the right of the Apple logo. If you need a place to mail it to, iResQ has done wonders for many of my friends - link is for mail-in, but they sell the screen itself as well if you want to try on your own (but take it from me, it's a bit troublesome and easy to mess up cables - I repair these for a living). Hope this helps!
