Hi, I have a Samsung LN41R71B. It's a HDTV LCD TV. The remote included with the TV has direct IR codes for TV (Antenna) and PC, but lacks direct codes for the other inputs (I'm interested in Component2 and HDMI), so I have to switch via "input next". I'm trying to discover if my TV is able to go directly to the other sources. I've tried the codes you supplied here (the first set, device code:7). The codes for On, Off, Antenna, PC and S-Video worked with my TV, but the commands for component sources and HDMI didn't. Any suggestions?
