More importantly, do you have the Pin Out to this TV which has a 3.5mm RS232 jack.  Is it two pin, three pin, or four pin?

I cannot think of a single reason you would use rs232 with this TV.  It is not going to give you Two way feedback. Unless it is just out of curiosity, it is a huge waste of time currently.  Just run it IR and be done.


The IR codes are well known and documented.  (I have posted most of the general known codes).
