I have a problem with my Samsung LCD HDTV. In the morning, when its first turned on I have a problem when changing channles. The TV doesnt seem to refresh fully and I get an impression of the previous channle bleeding into the new one. If I bring up my SKY menu to change channel, this also bleeds in to the new channel. Also motion appears blurred. This never seems to last for longer than 5 minutes at most when the problems sort themselves out. ANy idea what might be causing this?
