Many devices support discrete power (PowerOn, PowerOff) and input commands (like InputHDMI1) even if they are not on the OEM remote. Don't use the OEM remote to configure the device power and input settings. Instead use the commands from the device dataset. The first thing to do is see what is available under the dataset by doing a device Customize Buttons. Look at the "Additional Buttons". The left name is the LCD label name, and the name on the right is the command name (the ones your are after) associated with that label. The next thing to do is to try each found discrete power and input commands IN DEVICE Mode, making sure the action is indeed discrete and not toggling/cycling. Remember that the dataset is by brand rather than by model. So your particular model may not support all the commands in its dataset.

Armed with this info, it's now time to configure the device power and input settings. If the device support the discrete method (as tested above), then choose it, else select the toggle/cycling method. The Harmony supports both methods, but some devices support only the toggle/cycling method.

In the power settings, the discrete method is chosen when you select the option "different button for each" instead of "same button for both". Do not mix them. Don't use power toggling commands with the discrete method and vice versa.

In the input settings, method 2 is the discrete method. The list of inputs are label names (not command names). The command associated with each input label is on the next page (label on the left, command on the right). The input label names are used in the activity wizard. If you have to use a cycling method (like method 1), then make sure all the label names are in the correct order, and you answered all the questions properly. When you answer the questions, tell it what the device does (not what you wish it did).
