Go to your TV and manually pull up the device list and write down all of the inputs listed and the order. Then go into the TV device Adjust Inputs option and make sure that matches the TV EXACTLY. You can't skip an input or add an extra one because all the harmony does is keep track of where it is in the list and figures out how to get to where it needs to go by counting. If the TV is missing some of the commands to cycle through the inputs then increase the inter-device delay.
