I just got a brand new Harmony 550 and am very excited about it. It has been working great for me, but I am having one strange problem with it: It is failing to set the input on my TV correctly when I choose "Watch a DVD", but the Help feature fixes it every time. Here are the important components:
Samsung LNT4065F TV
Sony DVP-NS75H DVD Player (Hooked to input HDMI2 on TV)
When I click "Watch a DVD", the TV turns on, the DVD Player turns on, but the TV does NOT go to HDMI2. If I press Help, the TV DOES go to HDMI2 and everything is fine. The TV input is normally changed using commands such as InputHDMI2 rather than cycling through the various inputs.
Even if the TV is already on when I click "Watch a DVD", the TV still fails to change to HDMI2. So I don't think it's a problem with the Power On Delay of the TV (though I've tried adjusting that).
All other functions of the remote work great for me (watching TV through my cable box, switching to my Wii input on the TV, etc). All other Activities can correctly choose their TV input.
I've tried messing with various things in the setup. I've switched the DVD to a different input (AV1), adjusted various delays when it made sense to, etc. None of these help.
The ONLY thing I've found that helps is this (and this is the strange part): If I change the DVD player to be always on, everything works fine. But this is not the configuration I want to have my system in. If I change it back to powering off when not in use, it fails to change the TV input again.
It's almost as if sending the PowerOn command to the DVD player messes up the changing of the TV input command. And yes, I've tried increasing Inter-Device Delay on the TV with no luck.
I believe I have a pretty good understanding of how the remote works and how to adjust various settings in the software. This is what I believe at least...
I spent 40 minutes with tech support last night (trying all the stuff I already tried) with no luck. He ran out of ideas and said he would forward me to the Level 2 support, but I had to get going so he put a note on my account to let me go to Level 2 the next time I call.
Until then, I thought I'd put this message up here to see what you all think.
