Mysterious line of pixels

For those of you who own a Core Duo Macbook Pro (1.1, Yonah, you name it):

Take a look at this topic I opened regarding lockups and graphical issues (INCLUDING THE MISTERIOUS LINE OF PIXELS):

http://discussions.apple.com/thread.jspa?threadID=1878407&tstart=0

I solved this problem by cutting some excess Kaptop tape that was blocking the fan exhausts. This got me a serious temperature drop and that misterious line of pixels, the lockups and all the graphical issues just dissapeared.

Hope this helps at least a few of you.
Shame on Apple and the faulty manufacturing of a high-end product.

Best regards,
Lou.

Exactly the same issues here. My MBP 1.2, 17-inch, ATI Radeon X1600 is freezing more often every day now. I do not have time for this 😟

If you don't have time for it, you'll have to buy a new computer, there is no fix for this that is for sure, and replacing defective parts with more defective parts will inevitably lead to the same problem. Apple and ATI have not acknowledged the problem so nothing has been changed. Sam parts lead to same problem. And after all this searching the only thing I have found is that more and more people have this same problem

as well go to the feedback, and give negative feedback to apple.

I am also experiencing strange graphics artifacts with my 17" Macbook Pro 2.16 GHz. My computer has a Radeon X1600 graphics card and I am positive that this is the root of the issue. Reading this thread only confirms that. I am only posting to this thread so that apple will hopefully recognize that they used faulty hardware and extend the warranty like they did for the nvida geforce 8600M.

I have been having horizontal lines, screen noise, display turning to black, and computer freezes for the past few months. I have called Apple support several times, taken it to an Apple Store, and still have the same problem. However, I have a ATY,RadeonX1900 graphic card and a Mac Pro.

Hi All,

Me too, MBP 2.0 Intel Core Duo... i've posted in other topics with this issue as well...

If you have an early gen MBP with the ATI X1600 graphics card in it then you will probably be suffering from this issue, wuld seem to be caused by over heating. This will cause the screen to display odd 'effects', stray pixels (and/or lines of pixels), odd colored shapes appearing and disappearing (usually green or red)... Often if you min/max the current window it will clear the oddities but not always... The only thing i've found that helps is, dwnload and install smcFanControl (Google search it) and clock the fans up to about 3,000 min. (i have a couple of settings, 3,000, 4,500, & maxed at 6,000 so i can better control the problem)... It helps, but doesn't 'fix' the problem. IMHO It's basically the wrong graphics card, poorly configured. Shame on Apple!

The early MBP's also seem to have poor quality LCDs that are not dust proof so often you'll get black or dark specs, or smudges (bruising), appearing (usually at the bottom of the screen)...

I really think Apple should have done something about this, a recall or such... for most of us, it took a long time to figure out exactly what was going on, now way out of warranty!... I've been through the Genius Bar (ha!), and combo updates galore... But it's basically a shoddy piece of hardware we're all stuck with!

Hello. Just adding to the list. I have a 17 inch MacBook Pro Core Duo, RadeonX1600, and I've been getting the CMYK gradients/ objects across my screen for a while now (since I updated to OSX 10.5). The objects started out as pink, and now I'm getting white ones. It doesn't take a lot of usage before they start appearing on my display.

Here's a pic from this morning:

Hi anyone reading this Topic,

I can recommend "Fan Control" to _help with_ (but not cure) the issue/defect. Also, may be read through and join this Topic: http://discussions.apple.com/thread.jspa?threadID=1697470 You might also want to get on to bennettvonbennett mailing list (subject MBP ATI issues).

don't bother posting here. If you are at the end of this, go to the above mentioned other pages, especially the display anomalies page.

THIS IS A HARWARE FAILURE! not software there is no fix, except a logic board replacement or a new computer.

you can give feedback to apple if you want, but I would post your info on http://discussions.apple.com/thread.jspa?threadID=1697470&tstart=0

some ppl on that page want to organize an email list so you can add yourself to that as well

for the past week the display colors on my macbook look beyond weird - everything is dotty with red and cyan blue! i don't know what to do - haven't changed any settings - it tends to go back to normal from time to time but it keeps going back! the only thing i can think of is that something much have triggered it when i did a software update! i did a hardware test but nothing was shown - i was told by some one that it might be due to a loose wire... any advice would be greatly appreciated as i am traveling and there are no mac stores around.

I have the same exact problem - it happend a week ago - any advice?

"Same here, ATI X1600" Message to get it on moving there
