If it was me i would go into the stick menu settings under System then Power and re tick Turn Power Off after 4 Hours.
Then go into System settings again and under Control Other Devices re tick again the 1 - touch play.
Then go into your television menu settings and re enable the HDMI CEC control feature.
If the stick doesn't awake from a touch of a button on the smart remote (excluding the on/off standby & volume buttons which are designed to be used with your television only).
Then maybe try steps 6 first on this linked trouble shooting guide and if it still persists maybe try a full factory reset by following step 2 on the link but instead of holding in the reset button for just 6 seconds try holding in the reset button on the stick for about 15 to 20 secs.
