I bought a Panasonic 37" LCD two months ago. Everything was fine until a few days ago when the pictures on all channels became snowy. In addition to that the TV picture is not filling up the screen so there's a 2-3 cm width black line going across the top and bottom of the screen and sometimes on the sides as well. This happens on all channels (TV1-4 Prime, Maori). I don't have Freeview nor Sky so it just goes through a normal aerial.
Everything is fine though when I watch a DVD. No snow and the picture fills up the entire screen.
Could this be a problem with my TV? Or is it a broadcast signal problem or something else?
Any advice would be much appreciated.
