I have a Philips PW8807 model (same screen but without the pixel plus and surround speakers). I get a 1-2 pixel tall red/white stripe along the right-hand top of my screen occasionally when the screen goes black.
However, it doesn't happen very often -> mostly only when watching from DVD source actually, so it might even be the DVD player come to think of it.
Any ideas on screen setup to remove this would be greatly appreciated by me too.
