It
was FIVE Rivers Electronic Innovations and they're gone. They operated out of a former Magnavox plant.
More recently there was a company in Tempe Arizona named Syntax-Brillian that made the Olevia brand. They too are now gone, absorbed by Emerson. No indication if Emerson builds sets in the Tempe plant. I don't have high confidence in modern Emerson (chinese) quality.

But wait, there's more...if memory swerves, Sony was one of the first to have a plant in the US. Ontario Calif as I recall. They then bought the former Volkswagen factory in PA which they sold in 2008 to Hon Hai.
