This new receiver shuts off after 4 hours of no use.
Understood. Bloody nuisance compulsary power savings "feature".
My Samsung TV also does that e.g. when I'm watching a long movie.
"Press a button within 1 minute, otherwise I will enter standby" Grrrr.
Or when I turn my PC/media player off: "You have unplugged the HDMI cable".
I wonder if the people why design those things ever watch TV.
Can't you use e.g. a Nano and a 5volt phone charger with micro-USB lead.
A phone charger runs on fumes. Batteries are expensive
Sleep the Nano if you want to, or use it also for something else e.g. temp display or fancy TV background lighting.
