Hi, I am after some advice, i have had for around 4 months a SAMSUNG PS42S5HX, I am happy with the plasma, but since i have connceted my XBOX 360 up to it i am worried about screen burn ? What is the the liely hood of this getting screen burn on this screen ? I have got the feture that auto shifts the pixels to prevent it but didn't know if that was any good. Also is there any precautions besides switching it off etc that would prevent things like this happening to it ? Cheers appreciate your thoughts ?
