Finally got my first Plasma (Sony 42", non HDTV) up and running - love it. (Wife loves it too, so once HD arrives in New Zealand - about five years - we'll be going to at least 50", perhaps 60" if decent at that time, HDTV Plasma). But, and I know I've seen it on a thread here somewhere, my Sony's screen will be in the sun about an hour a day over the Winter - is this a problem? (If so, will covering with a blanket help? Cheers in advance.
