No. You can have a plasma screen the size of a house (if you can afford to get a manufacturer to build one – I think the biggest one you can buy today is
102”) as long as the electricity to power it is generated from a clean source like solar, with effective zero ecological impact. Semiconductor manufacturing is roughly as ecologically damaging as glass manufacturing, so a big TV has roughly the same impact as an equal mass of glass bottles, electrical wires, and plastic.
Unless you want to confine your viewing to daylight hours, though, you’d best have a big energy storage system along with your solar panels – a 400 W TV would need nearly a 200 kg lead-acid battery to run all night.
