The TV is a LG 55LW450U
I am currently using the Generic LG RS232 ucase proto template which is controlling the on/off of the tv fine.
I dont know about other functions as not used them.
The following is from the LG manual.

The main function needed is to turn on 3d mode with option of top/bottom or side/side. And obviously also to turn 3d mode off.
