If you are powering your Roku by plugging into the USB port on the TV, try powering from house power via the USB power adapter that came with the Roku.
The USB ports on some televisions only supply 0.5 amp or less, which is not enough to power a Roku reliably. A Roku connected this way often appears to start up normally, but if it runs into an activity that requires more power than the USB port can deliver, something will fail, commonly taking you back to the home screen.
If you don't have the Roku adapter handy, any other you have from another device should work as long as the fine print on it says it outputs at least 1 amp.
