Q: Strange vertical stripes - Continued

I never posted on the previous thread so here I am now. I acquired ia 15" matte screen MacBook Pro when it was about one month old in May. Only once has it misbehaved with the vertical backlight stripes. This was after I had been using it continuously for 2 months, waking and sleeping many times a day. Then it never did it again (its been 4 weeks). So just now when I read the post about how to reproduce the problem by taking pictures in Photo Booth, I followed the instructions. I took 20 photos and the glitch did not show up.

Err, as much as I don't want to say 'me too,' I can't help it.

This issue happened to my Macbook Pro when it was still relatively new (around May). Got so nervous back then but it went back to normal after doing nothing.

After two months, which is now, these vertical lines, uneven backlighting showed once again. And I cannot do anything about it. I tried all the suggested solutions in the first thread but no to avail.

This is such an expensive notebook and I don't know what'll I do if this cannot be fixed, replaced, whatever. I don't demand for a refund, I just want a notebook that works under its normal state. I'm just a student! T.T

I don't have a macbook pro, but I am considering getting one.
When the problem happens, can somebody plug his macbook pro to an external monitor?
If the stripes remain, I believe it's video card's problem.

Since the same problem also happens to some dell laptop model, I am just trying to figure out if it's related to the nvidia chipset flaw rumor.

No, it has been very well established that it is not a graphics problem. Besides, the Dell with the identical looking problem uses the Intel X3100.

Moreover, if you take a screenshot of the screen, the screenshot looks fine. The data going to the screen is fine. It has nothing to do with the graphics, it is a backlight problem, and it specifically is that a subset of the LEDs in the LED backlight that fail to enable when brought up from sleep or down from full brightness to somewhere slightly above 50% brightness setting (max-5 or 6)

Since I am interested in a light laptop, so I only search problems from dell m1330.
And some of them having screen troubles use 8400m GS, like this one:

From the previous thread, it seems to me the problem may not just come from one place.

This one looks like a LCD back lit problem.

This one looks like a video card error.

I just want to know the result on an external monitor.
And I am not asking screenshots. In fact, none of the pic in previous thread is a screenshot. I think we are good on this issue.

The subject of this (and previous thread) is #2 (mg2729smallnx2.jpg) which is the LCD backlight problem. Some people who did not read or look at the issue posted about unrelated problems as well.

I have my MBP connected to either an HDTV or Samsung external LCD monitor many times, and never ever had a problem, even while the laptop screen itself was showing the (LCD backlight) stripes.

Thanks for the reply.
People do post unrelated problems. This thread is for backlight problem.
Sorry for ask questions in a wrong thread.
I'll try to ask in another thread about the video chipset, if there's one.

it so terrible, I wonder what time will Apple solve this problem, 2000 $ for the laptop have problem with display.

I just got this issue today. I was looking at another computer display when I noticed the bars appear (literally all of a sudden) on my display. A reboot brought the display back to normal.

This is the first time that it's happened to my display--I do hope it is the last. However, from the accounts of everyone else...this is something that may happen a lot more than I'd like.

Come on Apple, please fix this problem.

Now I have the same issue also.
I read the long thread and found the hint saying that update to os x 10.5.3 should solve that issue. I am now running on 10.5.4 an today first time got the problem, after 2 weeks of never seeing it:

Last 2 weeks I mainly used the MBP just power plugged in, not running on battery. Never had the problem. Yesterday I unplugged the MBP and put the battery in.
Today afternoon I was in a meeting and switched the MBP on (not from standby) directly from startup and I saw the lines. Back home I had the problem again using battery power. Restart solved the problem also for me. But I don't want to live with that bug or is it a feature?!?

Now I plugged the MBP back again to power and unplugged the battery - problem could not be reproduced.

Any news or suggestions besides of waiting/hoping and returtning the MBP?

Quick question. Has anyone else changed their Calibration profiles for their LCD and selected 2.2 television gamma as their target gamma? I was just wondering because I did this two days ago and (knock on wood) the stripes have not reappeared as of yet.

I originally posted April 28.

Three months later the stripes have come back worse than ever.

I thought (hoped) the upgrade to 10.5.4 had fixed this non-problem that Apple's screwing it's customers with, but no such luck.

The few times I went to the Apple Retard Bar (That's what THEY call US, btw), they replaced the logic board, then the screen, but all without acknowledging the problem really existed.

I sell ART. Having a non-functioning screen is like saying I need a REAL computer.

And let me remind everyone that when you buy and pay for a NEW computer and three weeks later it's a refurbished computer, that's $500 bucks in Apple's pocket. Be certain to recommend to EVERYONE that they should NOT buy a new Apple, because in a few weeks they'll be working on a refurbished one anyway (if they don't return it).

Apple made more than 1 billion dollars just in the last quarter!!!!

And they can't or refuses to spend a little fixing this problem. I don't get it?

Is apple getting too arrogant?

My MBP is running fine after I sent it back for replacement or repairs. I bet there are a lot of people who sent their MBP back for replacement and/or repairs and now it is fixed. They no longer have need to read this thread. So you might not hear from them.

It's been over 2 months now with my replacement and still no stripes. However, I know that others have gotten replacements that had the same old stripe problem.

We need to flood apple with requests for replacement or repairs for these stripes!

Any lawyers out there? There may be a nice class action suit coming apple's way.

I last posted 24 June, at which time the dreaded striped had returned after a 7-week hiatus. Since that last post (4 weeks ago), I have not seen again... and I cannot even reproduce with photo-booth, where previously 3 photos and stripes appeared. Don't know if cured by latest OSX update, but I hope so... Could Apple have silently fixed this problem (or is my luck in)?

What did they repair/replace? Apple care is telling me they'll replace the logic board on mine, but I want to be sure that will fix the problem before sending it out.
