Hi Guys and girls,  new to this site and just registered.
Have a question - just bought a 50 inch plasma 2nd hand, screen  looks good etc but all i have is the "no signal screen".
When i press the menu button i get offered the usual selections, i then scroll to tv but nothing happens and always ends in the no signal box.
aerial etc in the right place - any assistance would be awesome
cheers - cabbydave
