A:AnswerThe answer above from Insignia didn't help. I don't think they understood the question. I don't need to know how to change or save last input. The problem is that, when using cable, and watching a show, during viewing, the screen will flash black (blank) for a second, and then the show reappears. This happens multiple times. This does not happen when watching the TV using wifi. So I am wondering if it's a problem with the TV itself or something that can be corrected through settings. It is not an issue with the HDMI cable, because I switched HDMI cables with one that I know works properly, and the temporary blank screen still pops up during tv viewing.
A:AnswerI spoke with the Mfr and this is a set that does not support ANY other remote. So basically if you watch TV via an antenna, to use the remote is ridiculously archaic... I guess the equivalent of "Vietnam TV 1965!". It's a deal breaker so the TV goes back.
A:AnswerIt is there but is labeled as "Audio Out" and has a headphone symbol.
Also, the RCA leads are input only, that is why you are not getting any sound out. They are labeled "AV In".
