I mistakenly hit the up arrow (channel button) on my remote. That changed the channel to where it won’t connect. I don’t have cable, I use a Roku. I’m not sure of the term there, auxiliary? I scrolled up and down through 120+ channels - no luck. What’s the next step? Thanks so much, Dave Lockwood

No, I must have an old remote. Somehow I found my way to the video input section - with the controls on the tv. I’m not even sure how I activated it, because I was unable to do it before. Anyway, problem solved - thanks everyone! Dave

if it says av on your control press it to see if you can get what your looking for
