Based on this past experience I have recommended LG TVs to friends and family. A month ago I recommended the 42LV4400 to my sister-in-law. Imagine my surprise when I programmed her remote and it didn't respond to the discretes for power or input selection. After a lot of searching, I am convinced the this TV does not have them. In addition, it seems that LG went out of it's way to make sure there were none of the usual workarounds that allow you to get the TV to a known power state or known input state. What a pain.
It seems that it would have been more effort to make the programming different in this model than to just leave it as it like their other models. I can no longer make a blanket recommendation to people who ask. Bummer.
