I've still got one of the last (NeoPDP) plasma displays. While it uses a bit more energy than OLED it's not 'a few hundred watts', but tens of watts. Also, since TV's have become cheaper a new TV will probably be a bigger one which uses more energy so there's less energy saving. Manufacturing a new TV will be a bigger energy sink than just using the old one a bit longer.
