Sony have already replaced one Grand Wega back projection TV which turned itself off many times during the course of one year, with the front lights flashing between red and green. The brand-new replacement set they gave me also does this. Although they replaced it, Sony have always implied that it wasn't the fault of the set, which is connected to an aerial, and a sky digi box, a video recorder and a cd player with scarts. I've changed over the mains, thinking it might just be a bad connection, but it still does the same. Does anyone out there have any idea what might be wrong?
