How is the av receiver attached to the roku tv, hdmi or rca cables? The rca input default looks like three circles with cable shown just short of being plugged in. Hdmi will have picture of hdmi jack. Either one can be edited ton say av receiver and may be show picture of a stereo. If you're not seeing any inputs on the home screen go into the settings> tv inputs> you see inputs that are installed and ones that aren't. You add the input from here and edit its name and icon.
I have a vcr/dvd combo unit attached to the three RCA inputs on the back of my Roku TV. There is not an AV tile on the home screen. I’ve looked at least 30 times in the last few days. There are only streaming channels, HDMI 1-3, live TV, and a computer tile. I have tried each of the HDMI, live TV, and computer tiles in case one was renamed. No luck. have been to TV inputs in settings at least 20 times and only have the option to rename or remove the AV tile. What else can I do? This is really frustrating!
No Roku tv has a computer input separate from the hdmi inputs. You have three hdmi tiles, so none of those are the computer tile you see, it has to be the av input renamed computer. Highlight the computer tile do you see just above it computer (AV)? That means its the rca input renamed computer, if you aren't getting a picture or sound from the rca cables attached to the tv via this computer input, then check the connections or try another cable. Then rename what you want and pick the picture icon of your chosing, it doesn't have to stay computer.
