Here are the discrete codes that I've discovered. These work with my new Insignia NS-39L240A13. I have them programmed into my URC-8910 using a device upgrade from the JP1 tools (keymap master, IR.exe).
I found 3 codes that work as a discrete Component input setting for this TV. The first corresponds to the VIDEO button on the NS-RC03A-13 remote that came with the TV. The other two I discovered while searching for the discrete HDMI codes. I suspect the Video button code is intended as a toggle between multiple component/composite inputs. This TV has only one component input and no composite input, so the Video button works as a discrete component input code.
The HDMI OBC 080 that others have posted corresponds to the HDMI button on the remote for this TV, which toggles between the 3 HDMI inputs.
The TV also has a USB input, and there may be a discrete input code for that, but I don't need it so I stopped looking after I found the 3 HDMI codes. I checked every OBC <= 170. If it exists it's > 170.
