Hello, can someone help me. I have a harmony 720 and a newer RCA LCD Tv. Here is the issue, when I use the remote to turn on the system, often times the Tv will not power up. With the Tv's original remote, I need to hold the power button down for about 3 seconds before the Tv will power up. How can I do this with the harmony? How do I get it to send the IR command for a longer period of time to the Tv only? I am sure it must be one of the delays, but which one?????
