Hi guys - just got my new SP50L7HX and there seems to be something wrong with it. The picture displays fine, however there is huge amounts of blocking around the dark areas & they look green. The on-screen menu seems ok, but no matter what connections I use, or if its SKY or my DVD player, it shows up. The picture is terrible!!!! agggggghhhhhh ( I would like to try reseting the TV but i cant seem to find anything in the manual on how to do this - and when i press the menu button on the remote the plug-play option does not appear, as the manual suggests. Really need help here!!!! Is it possible its set on secam or ntsc or something silly & if so how do i change it!
