Re: "get up out of their seat"
And do what, once they are out of the seat?
Have you actually tried to do anything using just the minimal set of buttons on the telly itself?
You're normally limited to buttons for power, channel up and down and volume up and down. If you're lucky you may have an input selector and sometimes a menu button. And if you're really lucky, there may be a physical power switch somewhere you can find it.
Whilst checking a Sharp telly I was given (without a remote), I tried to get it to re-scan the DTV channels after I had done a reset. Turns out you can't do it at all without the remote. Fortunately, I came across a code for one of my universal remotes that provided the "DTV menu" button needed. I also think that my main living room telly can't select HDMI as an input from the buttons on the telly.
