We've had the Samsung 50" for 6 days. For the first two or three days the picture on both DVDs and through Sky Digital were virtually flawless. Over the past few days though, the picture seems to have deteriorated. The main problem is usually things in the background: walls of one solid colur for example.....they have an annoying sheen on them, as if they're wet. The same exapt problem appears on DVDs too, so it's nothing to do with the Sky signal. Can anyone suggest what this problem is, or what might be causing it? It was so amazing for the first few days that this is really hard to live with. I feel like I might have adjusted some setting and not realised ther impact it had.
