Reset the tv not the roku. Vizio...Ok. Lets reset the TV. Please go to Menu>System>Reset & Admin>Reset TV to Factory Settings>Reset. Once the setup comes up, power the TV off and unplug it from power. With it unplugged, press and hold the power button on the back of the TV for 30 seconds. Plug the TV back in and turn it back on. Then go through the setup. If you don't have anything connected via a coax cable to the TV, you can skip the channel scan. If you do, you may complete the scan. Also please skip the registration. -GM
