Got mine today as well, sorry to hear a few are having issues.
I'm thrilled with mine(knock on wood).
My only HD source atm, is OTA.
So vast majority of viewing for a short while will SD.
But even then, the 'black barred' SD viewing area is bigger than the viewing area of my old 27" tube tv.
Just in case someone else needs it, the Vizio remote code for Dish Network's remote models 6.3(UHF Pro) and the 5.0(IR) that worked for me was '627'.
As for the lighted Vizio logo, I can't see it bothering me.
