Sony KDL40W590B and KDL40W600B
I know these are older models, but I'm trying to figure out what the difference is between these two models. Even Sony Support doesn't seem to know. They sent me a link to the manual, and the KDL40W590B and 600B are listed together, with no difference in specs that I can see. I'm hoping someone here might be able to provide some additional info. Thank you.
