Mine suddenly did the same thing! On and off button works and volume button works, but home button…zilch. I tried unplugging and rebooting the Roku device. Didn’t help. So, pressed the power button on the remote (which also shuts off my tv). I then pressed THE HOME BUTTON, (not the power button) and the tv came back on, and ALL the buttons work again! WTH?
If your Roku has a "Settings > System > Power > Auto power savings > After 20 minutes of no interaction" setting, try disabling it.
Hello it recently happened again! I have an older Samsung TV (~15 yrs old), I had to reset the Samsung software and it started working again. I bet Roku doesn't perform regression testing with so many older versions of TV's. So it's now working again!
I'm in the same situation. How did you reset your Samsung?
Jennifer15, try unplugging the power to the TV for several seconds. Simply turning a TV off and on doesn't really do anything.
