How to Switch TV Input on Roku TV

Yes, on the TV remote, there should be a button with a label like Input or Source.  Possibly some TVs have it on a menu. The Roku doesn't change this - it's the same button you use to get to the cable box, the blu-ray/DVD player, etc.

If you can't find it, try looking up a manual for it, or give us the manufacturer and model number of the TV and someone here may be able to find one.

Is this a Roku TV, or do you have a Roku player connected to a different brand of TV? If it's a Roku TV, the remote does not have an input button. You have to select a different input on the home screen.

Problem solved. Disconnected the Comcast cable from cable box to tv and using the HDMI output on the cable box. (never knew it was there) Now I can select from home menu. Thanks for all the help.
