My laptop doesn't connect to tv any more

[Uff]

Hi. I am using Samsung NC10. In December, 2011 it's screen stopped working. Well actually it's working but the picture is so colorless that I almost don't see anything. My solution for that was to connect my notebook to TV. I bought VGA cable and it worked for 4 months but now it doesn't work. TV says it is connected but there is no picture in it. Can anyone help me?

Is there a key combo on the laptop to toggle your screen between the builtin display and the TV (on ASUS it is Fn F8)? Also reseat your VGA cable.
or go here (if you can still use the laptop display) Control Panel\All Control Panel Items\Display\Screen Resolution and make sure you are set to use Display 2.

Do you have another TV or external monitor you can test with ? (just to rule out a bad cable) ?

Did you already try pressing Fn F4 a few times?
