Welcome to our community.
Regrettably, what you hope to achieve is not generally possible with a basic remote control. Additionally, once you've found codes that control any functions of your TV, there is not a "better" code we can provide that will offer more functionality. The only remote guaranteed to work with your TV is the one that shipped with it in the box.
With that said, I wanted to achieve the same thing for my TV system at home and the only way I could find was to purchase a Logitech Harmony remote. It allowed me to control my devices the way I wanted, including having the TV remain on when I changed signal sources using the macros.
I hope this helps. Thank you for writing to us.
