I have recently set up my Tosh 36ZP18P screen with Sky+ and a Panny HS2 recorder. All was fine when suddenly today I was doing some recording from Sky+ to HS2 when the screen went red and misty in places , then green, blue etc etc. If I flipped it to AV1 to watch it properly it was fine , however if I flip it back to AV2 then its the same. Does this just sound like a dodgy scart cable thats messing the RGB ??
