I'm having the same issue but only on one of my three Roku TVs. My Philips is the one causing problems.
They always gotta do something to break what didn’t need fixing, now you gotta go through unnecessary confusing steps to access these things, my older relatives don’t understand all that and it was easy for them to access everything straight from the home screen now they can’t watch their cable cause they can’t remember how to access the inputs, I don’t understand how Roku can f things up this bad and make me not wanna ever purchase a device from them again when they were my favorite cause of the simplicity of how to use everything right from the Home Screen, why did they do this, why, it’s pissed me off so bad I’m seeing red they need to fix it and take it back to how it was, they always gotta screw up as good thing and it makes no sense, their was no real for them to do this at all as those inputs on the Home Screen didn’t impact any other features being there
@rosept10, I agree, but if your relatives mostly use the cable box, set the TV to always power on to its input under Settings->System->About. Then if they have trouble getting back to cable tell them to turn the TV off and on again.
