How to use "on" and "off"

 Sunday, May 22, 2016
 Someone said this to my hearing: "Off the TV and on it again". Do you "on" and "off" an appliance? Hell no! Let me emphasise that you add "put" or "switch" to "on" or "off".
 Hence, the extension should be: "Switch/put off the TV and switch/put it on again".
 Kindly note!
