I can't boot into my Leopard disc

[kidwithdimples]

I have a uMBP 2.26GHz with 4GB and 500GB HDD.

I usually do the Disk Utility every once in a while and it recommended me to use the MAC OS X disk and repair the disk. I inserted the disk, restarted and held "C" and the disc was running and everything. Like 1 minute later my display went black but I can still hear the disc running.

But that's all it happens. Everything runs but my display went black.

This is a 3month old uMBP.

This is the log from the Disk Utility

Did your Mac ship with Snow Leopard? If so you won't be able to use a Leopard disc.

this happened to me when i tried reinstalling snow leopard from scratch. your computer booted the disk properly, but the backlight isn't on. get a flashlight, and shine it on the screen.

Sorry I meant Snow Leopard and shining a flashlight on the screen worked.

Thanks
