I have just finished programming a Harmony 688 for a JVC HD-52Z585. The remote works very well with the TV. However, there are two problems I ran into and my solutions.
First, the Harmony codes for up, down, right, left and select do not work. I just added them by using the TV remote and they were downloaded to all of my picture settings for the components I am using.
The other problem was that the remote would not tune into the cable TV input. The problem is that to get to the cable TV input Harmony appears to input a 0 or 00 code. If that is not a channel on your cable, then the TV will revert back to the last input. I was able to overcome this by going into custom settings when setting up the Watch TV activity and adding "channel up" to the activities on start up.
