Screen suddenly looks like a colorful barcode

Question

I was switching between apps and my screen suddenly went all-white with a lot of very thin vertical lines, so it looked like a big colorful barcode. I pressed command-option-eject to put the computer to sleep, and that worked. Then I woke it up and the screen looked fine.
This is a brand new machine, so if there's a real problem lurking, someone please tell me so I can get it serviced before the warranty ends. Thanks.

Hey.
I've been having exactly the same problem since two weeks.
Let me explain.
While going to school, i had to finis a work in the bus, so i power on my laptop, and immediatly turn into a nice colorful barcode. I was very because i thought i had broken my laptop, while hanging it in my laptop case.
So i close it immediatly, and re-opened it. The barcode disappeared.
Okay, so at school no problem at all.
I got back home, no problem at all either. But in the night, while watching a movie in my bed, my laptop, which were 1 meter far away from me, turned into the barcode, without touching it at all.
GREAT!
i closed it down, reopened it, but the barcode didn't get out as well the first time in the bus.
i am getting very scared.
after 15mins of trying to open it, close it, the barcode still belong on the screen.
i fall asleep.
And the problem is still there.
I went to the Apple reseller, where i bought my Macbook Pro unibody 15" late 2008. And showed him.
He told me that the screen is broken, or maybe the gaphic cards.
But my laptop works perfectly when plug into my Apple Cinema Display. I am using dual link dvi, and works perfectly.
But something strange, about my unibody, is that, the day i bought it (nearly 18months ago), i noticed that the headphone jack hole were very loose, so loose that if i just touch my headphone, it will unplugged and play sound on the built-in speakers.
So I brought in the two weeks after my purchase, as this became very very annoying to use. We also noticed on this day, that the whole screen part were shifted something like one millimeter all along my laptop. Really strange.
The guy tested the macbook. And at least, he told me something like "Well your macbook works perfectly, maybe they were a problem while mounting your laptop, but as it works perfectly (hardware and software), no need to send it to Apple
Warranty Service".
Great.
But now, it's seems that there is to much problem and issues ont my laptop.
I remember having many problems with it.
-in the firth month of use, my macbook pro didn't go well into sleep mode (like many people in this forum), so sometimes i found my laptop on my desk, getting warmer and warmer, while being in sleep mode.
-really nice video glitch while plugging my macbook on my apple cinéma display 30", video getting black/vertical
-many firmware problem (like backlight keyboard in my Xp Boot Camp partition, with the superdrive)
-the headphone jack issues, wich is REALLY annoying, i found a "cheap" solution, i bought a behringer audio card (19euros)
-and now the screen issue, which cannot let me use my laptop as a portable computer. Do I have to bring my own screen everywhere i go?
I can't imagine i bought this computer 2200 euros.
