Currently Being ModeratedNov 23, 2008 4:12 AM (in response to v@noffski)This is a known defect. Nvidia shipped defective boards. My macbook is totally dead after having a few months of horizontal lines. You mac will eventually fail. Apple should fix this by replacing the motherboardMacbook Pro, Mac OS X (10.5.4)

In this case they use ATI, it`s an older MBP from 2007.

Currently Being ModeratedDec 19, 2008 12:06 PM (in response to v@noffski)I started to see similar issue few months ago randomly (once every few days) but now it's happening several times daily (1st gen MBP with ATI graphics)
Opened a case with Apple and after going through extensive diagnosis they suggested to replace graphics card. Unfortunately i can't take it in for repairs since all Apple authorized service centers in Ottawa, ON require you to leave your laptop for a week just to look at it, let alone order the part and actually fix it (i use the MBP at work as my main/only machine so can't leave it at repair center for weeks). Really lame.
Anyone else got their graphics card replaced? did it fix this issue?MBP 15.4" 2Ghz - 2GB RAM, Mac OS X (10.5.6)
Currently Being ModeratedDec 31, 2008 6:40 PM (in response to masterfu)I have a Macbook pro 2.0ghz ATI Radeon X1600 graphics with the same horizontal lines and freezing when its running hot and/or I'm gaming... I just reapplied the thermal paste and cleaned out all the dust, but it hasn't solved anything. I'm planning on giving Apple a call seeing how hundreds of people have been having this type of problem and seeing whats up, even though my warranty's already out. If anyone has gotten a response from Apple, please leave a post about the details. Also, it seems like the majority of the problems are from the ATI graphics cardsMacbook Pro, Mac OS X (10.4.11)
Currently Being ModeratedJan 6, 2009 11:46 PM (in response to EvANighT)Just to add another data point to this thread. I have the horizontal lines as described in the posts here as well, and here are some photos of my display:
Lines appear to be random, can't really say if they appear when the MBP is hot or cold.
My lines appear on the LCD and on an external display.
Techtool Pro reported a failure of video RAM (VRAM), but Apple diagnostics from the original DVD found no problems. I have two Samsung RAM modules installed for a total of 2GB, so I've tested the MBP with only one, then the other, and again both but in swapped positions. No change - lines still appear. So, unless by some chance both RAM modules went bad at the same time, I think RAM can be ruled out as the culprit.
Anyway, if someone has figured this one out, please post your findings.MacBook Pro 2GHz 15", Mac OS X (10.5.6)
Currently Being ModeratedJan 10, 2009 10:59 AM (in response to Omar Filipovic)Hi
The same problems started to appear on my display as described and documented by two previous posters.
I also had multiple crashes of my MacBook Pro lately.
However, they had been linked to heavy CPU loads (EyeTV).
Nevertheless, the horizontal lines are becoming now a more 'constant' feature, which is really annoying.
Anyone with any ideas, or are we out of luck?

Currently Being ModeratedJan 10, 2009 11:22 AM (in response to Egg1234)I did some testing recently and the issue is definitely heat-related. I installed Temperature Monitor and watched the temps while running iTunes with the visualizer on. When the temperature of the Graphic Processor and its heatsink go over about 50 deg. F, the lines begin to appear. Soon after that the system will freeze. Sometimes iTunes continues to play, but the keyboard and trackpad are not responsive, and other times everything freezes completely.
Next I installed smc Fan Control and if the fans are running at top speed, I cannot reproduce the lines on the display.
I have the same machine as the previous poster, Eckkhard, and I too use EyeTV with this MBP.
My guess is that the system is no longer controlling the fans properly and letting the computer overheat, or the heat dissipation devices have lost their effectiveness. This could mean dirty fans, deteriorated heatsink compound, or perhaps a temperature sensor failure. Don't know until I open it up to take a look.
Currently Being ModeratedJan 10, 2009 12:41 PM (in response to Omar Filipovic)Omar,
just out of interest: has the crash log (console) revealed any information in respect to the freezes?
I wasn't able to find any entries related to these events, but maybe I wasn't looking thoroughly enough...
On a different note, I just realised that my MacBook Pro is still covered under the Apple extended warranty (lucky me)... So watch the space...

Currently Being ModeratedJan 10, 2009 7:04 PM (in response to Egg1234)Eckhard,
I was unable to glean any useful information from the console. As if these freezes weren't recorded...
If Apple decides to perform a radical fix, such as replacing your logic board, see if you can press them for more information about the actual cause.MacBook Pro 2GHz 15", Mac OS X (10.5.6)
Currently Being ModeratedJan 11, 2009 6:07 PM (in response to Omar Filipovic)I've got a 17" MBP 2.16 that I'm having the same issues with. Screenshot of mine is here:
I can confirm that Omar's research on Graphics temperature as being the apparent culprit. I've been running the Graphics Processor and Heatsink in the low 40's range with no issues appearing at the moment.
A fix besides using SMC Fan Control would be great if anyone comes across one.17" MBP 2.16Ghz, Mac OS X (10.5.6), 2GB RAM, 120GB HDD, 256MB Vid, DL Superdrive
Currently Being ModeratedJan 15, 2009 12:50 AM (in response to Russ Williams)My MacBook Pro is becoming now more erratic (i.e. it needs less and less GPU and CPU activity to freeze).
Spoke with my local Apple Service and will hand it in tomorrow, should have news the coming week.
The rep said it sounded most likely to be a logic board failure.
Keep you posted,

Currently Being ModeratedJan 15, 2009 11:51 AM (in response to Egg1234)i was having the same issues as Eckhard, with occasional freezing and horizontal lines. I took it into the Apple Store and they ended up shipping off to a repair depot for fixing. The Apple Genius said it would take 5-7 days for it to come back; they would overnight it to me at my home address. I took it in Monday afternoon and got it back today.
So far, everything's been fine graphically and such. They note parts replaced in the product repair summary, which included item #630-7753 Logic Board, listed with the symptom "Distorted Video"
Thankfully, my AppleCare doesn't expire until this August and I was fully covered at no charge.MacBook Pro 2.16GHz Intel Core Duo/2GB RAM - AUG06, Mac OS X (10.5.1)
Currently Being ModeratedJan 17, 2009 8:26 PM (in response to masterfu)At first I thought it was heat related, however most MBPs and other Macs can run normally well over 60 degrees Celsius (mine did for a year or two before this happened). Seeing how most people who have this problem also have Radeon X1600 graphics cards, I am assuming it is this particular graphics card. Either that or the settings has changed for the "emergency shutdown" (default temp. lowered?)- it triggers when the computer is running dangerously hot. Thoughts??Macbook Pro, Mac OS X (10.4.11)
Currently Being ModeratedJan 17, 2009 8:32 PM (in response to masterfu)Oh and another thing to note is that when I have cooling for the Macbook Pro, the pixelated lines don't appear. The cooling was very intense (about 40 degrees Fahr.), but then I wouldn't have any problems running graphic-intense programs. Without the cooling, it would usually freeze. Macbook Pros aren't meant to require any type of cooling though..(another macbook pro 17" that we have runs perfectly fine without any of this even though if its put on a pillow and gets VERY hot)Macbook Pro, Mac OS X (10.4.11)
Currently Being ModeratedJan 26, 2009 4:57 AM (in response to EvANighT)Hi you all,
there is a thread out:
We are at the and of the discussion yet.
1. Your Logic Board is broken, precisely the GPU is damaged
2. it Heat related but its getting worse over time till your MPB is unusable
3. it will lead to horizontal stripes, CYMK Gradient blocks, Stretched screencontents, at least hangups
4. We have some people in our thread replaced the board by apple care. Only answer: Logic Board replaced due to "distorted Video"
5. Only solution: Replace logic Board
There is nothing u can do about that issue than putting your MBP into a refrigerator and hope.
I am wondering that thru:
People with a NVIDIA GeForce 8600M GT and a similar issue got a replacement for free AND they got their money backwards if they already paid for it, before releasing this apple article:
*Apple is issuing refunds to customers who may have paid for repairs related to this issue. Please contact Apple for details on the refund process.*
Please help and:
1. Join our thread. Everybody of you should post a
"Same here, ATI X1600" Message to get it on moving there
2. Do a feedback about that to apple - click:
there you can send a feedback report to apple. Please do this, write down your problems and paste a link to
into it. If there are enough bad feedbacks pointing to our problem, they maybe will start reading this thread.
