When I try to boot from live cd I get a blank screen HELP!

Question

I've created a bootable USB and tried a Live CD. Both times when I boot from them I can hear the Ubuntu drums but have only a blank screen. I have an Asus with quad core A6 processor and Radeon HD 6720G2 graphics card.

What should I do to solve this?

P.S. works fine with wubi.

I had similar problem. But I didn't hear the login sound, just saw the black screen. The --nomodeset boot option helped to solve the problem. Read there for more info
