Macbook pro mid-2010- water damage - but still plays chime?

Hey guys it's been a week since my macbook pro had water leak into it, Im pretty sure something is fried :(

But now when I try to boot it up I hear the startup chime, what does this mean? Should I buy an Mini DisplayPort to HDMI cable or give up and just try to back up stuff from the hard drive??
