Hi, I got my Tosh about 2 weeks ago and love it. However, (I'm no TV techy so excuse the layman terminology here)... I've noticed some shadowing on the screen, it's not obvious when watching TV but it is very obvious when I turn onto an unused AV channel and have the blue screen turned on. 2 obvious darker patches at the bottom of the screen and another thinner darer strip running up the right hand side. I wondered if it was some sort of magnetic inteference from my (also recently acquired) Sky+ box, but I disconnected it and took it out of the room and there was no change in the shadowing... Does anyone have any obvious answers to this, is it a "don't worry about it" thing or should I be testing the JL 5 year warantee ? Thanks in Advance.
