I have a Vizio TV and just recently purchased a Super Nintendo with a coaxial cord. It plugs in and turns on just fine but I can't find a channel that works with it. HELPPPPP!!!!
I have a slightly similar issue, only mine is a brand new Vizio smart tv, which has Composite and HDMI ports. I can connect just fine, but it gives me an 'Unsupported Mode' error. anyone know wtf to do on this?
