Okay, so I've figured out that they restructured the service menu with 2011 tvs. Now, you can access the advanced menu by slowly pressing 0000 one inside the normal service menu. Then, the options for UART are MDC, On1, On2, Auto Wall, and Debug.
I still can't get any response over the service port, though. Any thoughts on what these options mean?
