The commands in the database tend to be brand generic rather than model specific. Although the database has discrete input commands for your TV brand, your particular model may not support them. Try all the discrete input commands in device mode paying attention to their behaviour. If the ones you need work, then change the Adjust inputs to Method 2 and configure it according to your findings. Else, there is no easy way to find if a particular model support discrete commands.

Note: You may also want to try a similar model ending in LD500. It's possible the dataset for your particular model has the wrong discrete commands.
