I bought a set-top box (UK Freeview) and thought to myself
"hang on a bit the box is as warm with green LED on as on red standby"
I measured consumed watts in both states and standby is 80 percent of the on
state. I put in a hard on/off switch , data held in EEProm or whatever and
no difference in function except programme info pages takes a couple of
minutes to gather

I checked my VCR/DVD player one day and found that it drew exactly the
same amount of power when "off" as it did when "on". The power button
was essentially just a placebo.
