Hi, I set up my new Panasonic Viera plasma last night. It was working OK for about 20 minutes, then I noticed a fine line about halfway up the screen going horizontally across - this was on all stations, both from Sky & the normal aerial. I went out of the room & when I returned the picture was completely scrambled, sound is fine - again on all channels. I cannot bring up the menu screen & the set now turns itself off after a few seconds. Obviously I will contact the dealer on Monday, but I don't want to repack it all if it is something simple (I am a complete muppet at this stuff!). Any suggestions gratefully received........... Many thanks!
