Macbook Pro to TV

Greetings,

I'm a relatively new convert to Mac's, so please forgive my ignorance.

Last night (slightly inebriated), I hooked up my Macbook to my plasma tv using a converter from the port to a vga cable into the tv. I can't remember what I pressed (beers didn't help), but I think I went along the old PC line of fn F4 and it switched over. Now, the next day, when I plug it in again, it says no cable in (on the tv) and no matter what I press, I can't get it to come up again.

if anyone has any ideas, they would be greatly appreciated.

Cheers

Mike

Hi Bob,

I looked at the link your provided, and I didn't find the answer.

Would letting my Macbook update its software have any effect? (I did this last night before sleeping.) Because when I plugged it in yesterday, it recognised the laptop immediately, and changing the tv screen to a mirror was done by the Apple button and one of the screen brightness buttons (I think).

Any further help would be great.

Cheers

Mike
