    We finally upgraded to a flat screen from an old tube TV. It's a Vizio LED LCD that like all new electronics doesn't truly shut off. On top of that the light that stays on is quite bright.

    Also got FiOS, and I noted that it is possible to have the box cut power to the outlet on it when shut off. So I was thinking of doing so, and plugging the TV in there. Is it safe for the TV's components and software to repeatly cut power to the outlet without turning it off? Another way to phrase it, do new TVs, and other electronics, need to shut down like a computer to prevent damage?

    Already running the experiment with a Panasonic plasma TV:
    There are two schools of thought and personally, I believe as long as it is under warranty, use the most demanding protocol that optimizes the set for your use. Before the warranty expires, use a Kill-a-Watt and measure the idle, electrical load.

    One problem with turning off at the outlet is something called "in-rush." Many power supplies have a full-wave bridge that feeds a large capacitor. Initial charging of the cap leads to a short, 20-200 ms., very huge current spike that can 'trip' other systems. What you want is a 'soft-start' power supply but this can be done 'after the fact' using an inrush thermistor.

    I have FIOS and a router and a flat screen TV.

    Use the TV off button to turn it off the TV off. They have "warm down" routines to reduce potential damage to the screen due to thermal cycling. If yours is like mine, you can more-or-less listen to the end of the "ticking" to know that the screen has cooled down enough for complete turn off, via some power strip or similar.

    So here's literally what I do. I have FIOS. I turn off the FIOS router when not in use, using a timer. So that just plain is off (e.g.) 12PM to 8AM. Completely separately, when I'm done with the TV, I turn off the TV at the TV. When it has finished "ticking", I turn off the power strip that feeds the TV.
