I'm following up my earlier post on not being able to get sound out of my speakers without having the receiver turn on a few seconds after the TV. I was looking around at another forum (sorry, AVSForum) and read something that looked like it might work, so I tried it on my TV and it works. If you click on Apps on your remote, and then select VIERA Link (which should be the third selection from the left on the row above the larger group of apps), you will get the VIERA Link menu where you can select your speaker output. The choices are TV and Home theater, and apparently TV is the default. I selected Home theater, and the sound now comes out of my stereo speakers instead of the TV, even when I turn on my TV, HD DVR, and receiver all at once using my Harmony remote. I had Harmony Logitech tech support take out the 5-second delay in turning on my receiver that I previously had them input, and everything works right now, and the sound comes out of my stereo speakers instead of the TV.
If you click on Menu on the remote, then click on Setup, and then on VIERA Link settings, you will not find the menu option to output the sound to your stereo speakers. Why Panasonic made this choice so obscure, I have no idea. I also have no idea why none of the many Panasonic tech support people I talked to weren't aware of this option. The Panasonic eHelp Manual talks about this on p. 144 of the manual for the VT60 series under VIERA Link HDAVI Control, Speaker Control. It isn't very helpful that Panasonic buried a function in its manual that many people would want to know about, but that's what they did. Hope this saves other users time and frustration.
