I have a new TCL smart tv. It had an option to install ROKU tv. Since I already had an Xfinity DVR, a complete set of programs with comcast, a subscription to Amazon Prime and an Amazon Firestick I did not install the ROKU program. However, curiosity got tha best of me so I did install it to check it out and now it is interfering with the other programs. How can I set my TV back to the original settings?
I had a similar problem, but not with the ROKU. All smart TVs should have a Factory Reset option buried in their menu somewhere. In fact, my oldest TV (65" VIZIO) has a built-in PDF manual permanently installed. I only discovered it the other day.
