I have a 40 inch vizio smartcast that is 3 years old. When I go into smartcast to watch paramount or prime I cannot get back into my local channels. I can go into the menu for the TV and it says I have the 9 analog channels but I cannot do anything past that. I did a factory reset and was able to watch them again . But as soon as I went to smartcast they disappeared again. Anyone else have this problem?
