I have a Roku streaming stick. When I plug it into side of my TV (LC-65LE643U) it turns on and I can use it normally. I have recently bought and set-up Onkyo HT-S3500 Receiver which has 4 HDMI inputs, but I cannot seem to get the Roku to function at either one of them. I plug it in, select a source and nothing happens. No logo or loading screen. Thoughts?
