well, after going through a 100 hour warm up period with low settings, only using cinema mode, contrast below 50%, I let the family use the set. My daughter had cbeebies on for 4 hours, one day, about 2 the next, and 2 the next 2 days. I turn on the grand prix today, and guess what, I have a cbeebies logo in the sky. I read the nice little cop out clause on page 56 of the manual. But this hardly constitutes misuse of the set. Will phone them tomorrow for advice. Most tv channels these days use logos. (the grand prix was 3 hours solid with a white F1 logo bottom left) They seem to be saying yes it is a tv, but dont use it as one. Trading standards will be my next port of call after that..
