I have a Proscan 42LED55SA LED LCD tv, it's my first HDTV. I am pleased with it overall but lacks some features to be desired. Such as channel labels...I want to be able to label my channels but this one doesn't have the option to do so. I am pretty sure RCA makes Proscan but not sure. I figure with today's tech it would be able to update firmware but can't even find a contact source for Proscan to ask. Anyone know how to contact Proscan?
