I wonder what happened to my Imac screen?

Hi.
I have an Imac Mid 2007- 20" 2.4 GHZ 4 GB RAM - Snow Leopard 10.6.2 .
Lets come my problem;
The previous week, seemed white stripes on my Imac's screen by me. It occurs suddenly. I closed Imac immediately. After re-opening; the six-bay had become the opening screen, such as the former showed the top. Lines also disappeared.
Rate what could be the problem? I think it is related to graphics cards. After removing the computer to sleep and get over the hump for a few seconds then the screen is black. This shows us that the problem display LEDs is not it?


Below I've included the pictures.



Thank you for your interest.

I'm sorry. I guess I don't understand your problem. Your thumbnails look like a normal boot up sequence to me.

Then its not just me....I dont see the problem.

To summarize, if necessary, is not fully understood from the pictures but the screen darker than the top six. Line after the incident was mentioned above.

i dont mean to be glib, but..... I truly have no idea what you just said.

I guess I could not tell the problem exactly . The previous week when I was surfing the internet, some white stripes occured on my screen. I closed the Imac immediately. After I re-opened the Imac, it's screen had broken. Mayby, you don't see the problem from my pictures otherwise underside of the screen shows the dark,

top of the screen is bright.
