I bought a Vizio SV420XVT and it does not have the full "Program Guide" when I press the guide button twice. It shows info then clears on second press. I called their tech and they say it was removed in a firmware update. It is a refurbed unit from an authorized dealer.

Also if this is true can I flash it with different firmware from somewhere on the internet?
