Sony has a tendency to do that. I have a Panasonic DVD recorder that is a little more polite. It flashes between "please" and "wait" during power down. Some remote units have an extra switch in the back of it to turn off the remote receiver, when going on vacation or other. The only true standby I can think off of hand, is on tube gear. It shuts off the high voltage to the tubes, but leave the filaments on to keep the tubes warm. Some TV's had that option until roughly the mid '70s. The government griped they were wasting energy. It was convenient to have an instant on TV back then, in the CRT days.
