I experimented with my TV and the only input that toggles the tuner is HDMI 1. I seem to have a second HDMI 1 code also and that doesn't change from HDMI 1 to tuner. None of the other source codes go to tuner no matter how many times you press.
I have codes in my IR Data file for the descrete codes for the TV but I have no idea how to share them and I have no idea how to use the codes posted on this site. This is all new to me. The file number 464 on the URC Data base is what I used and it must be new because it's the last file of the data base and I just downloaded the newest database to get it. I also read that our TV has had a firmware upgrade and the codes were changed or codes were added, not sure.
BTW, I have buttons for all three HDMI input buttons, PC and every other source but I didn't download them to the remote and try them since I only use one of the three HDMI inputs on the TV. Maybe I'll give it a try and see what happens.
