I don’t know if Sony manufactures LCD’s at its television plant in Pennsylvania or not, but given your record at locating television plants in the U.S. (after claiming there are none), I suspect you don’t really know about LCD manufacturing either.
My friend, there aren’t any LCD manufacturing plants in the US. There aren’t any television manufacturing plants in the US. There are some vestiges of assembly, ‘tis true.
Vacuum tube production of the type you are referring to left the US in the 90s sometime, probably to Mexico.
Given that you are arguing over minutae and splitting hairs is pretty sad, considering the US was at one time the worlds leading exporter of electronics. I’m not the enemy here, just trying to bring facts to the table. Have a good day?
