I have a Roku streaming stick and when I turn my tv off at night, the green light on the stick still glows for a while lighting up the room. I'm not sure how long it stays on but it stays on for a while. Is there a way for it to turn completely off to get pitch dark. It's driving me insane.
No - you can unplug it or cover it.
There are also remotely controllable power supplies/strips that you might consider as well.
@ashrae9504, the light goes off when the screensaver starts. You can change your screensaver wait time under Settings->Theme->Screensaver wait time.
Black electricians tape over the LED works wonders ...
