When I turn on my phone, the screen looks like its burning.

The power button is broke, so I tried to connect it on my computer, and when it turns on, the phone boots, but 4 seconds later, the screen starts to burn until it's totally white.

I tried to find information in internet, but there's no information about this, I think i'm the first with this problem.

UPDATE: While turning on the phone, 1 second after turning on, white stripes and flashing stripes appears, also, a big white spot on the center of screen, also white. All of this slowly appears on screen. If the phone turns off, this starts again (the screen appears normally and then the white things appears)

I hope you could help me with this, this phone means a lot for me.
