Anyone PLEASE HELP!

I have bought a Harmony One remote and I can't get the darn thing to work with my LG TV with regards to the input selections around activities. The remote that comes with the TV only has an input toggle and the Harmony One doesn't handle this very well. If anyone has the discrete codes for HDMI 1, HDMI 2, and HDMI 3 for this TV (52LB9DF) - I would really appreciate it!

Regards,

Tim
