In spite of me telling my mate who's visiting me to not keep the same image on the screen for a long time I came down this morning to see the TV on with a DVD menu on He had left it on this screen for about 5 hours and there is now shades of retention all over the screen on certain colours! GRRRRRRRR!!! I was very angry. Now, i know that it's best to leave the snow screen on, but it keeps turning itself off automatically after a time. Anyone know how I stop it from doing this? Thanks for your help. I have calmed down now and forgiven him- a few choice words were used, including "one thousand seven hundred pounds", "my pride an joy", "are you stupid or something?" etc.
