That the Toshiba's Picture Frame TV's have a tube fault. I have heard (from a service engineer) and read a few members of the forum who have had to have their tubes replaced. If so does this just apply to the picture frame 2 TV's? Is the same tube used in the picture frame 3's? Have Toshibe acknowledged that they have a tube fault. I have recently returned a Panny 32PPD30 and am now looking at a Toshiba 32ZP48, but have concerns regarding the reliability of the picture tube, especially if outside the warranty period the tube packs up, which can be up to 1/2 the cost of the set.
