Help needed: Laptop screen goes black when HDMI cable is connected

Hello,

My laptop's screen goes black when I connect it to the TV via a HDMI cable, however this is completely new as it used to work fine. I can still watch things on my TV but I have to look at the TV screen where text comes up quite small and it makes it hard to do stuff, so I was wondering if anyone would know why my laptop's decided to start doing this, and how I can get it back to both screens working at once? The volume and everything else works ok, it's just a bit annoying is all!

I have Windows Vista Home Edition, not sure of the details, but I got it just when Vista first came out.

Thanks!

do you have your drivers set to "clone mode" in your CP? (the bit where you set up multiple displays
