Not sure exactly what you mean?
There are often IR commands that aren't on the remote that comes with the TV.
Usually these are discrete power on and power off rather than just power and discrete input selection rather than having to scroll up or down a list of inputs. They exist so that macro commands can be created reliably when a universal remote is programmed.
Those can usually be found in the database for universal remotes like the Logitech Harmony, pro remotes from URC and RTI, and home automation like Crestron or Control 4. They are not available on low end universal remotes since they have neither the ability to make macros or enough extra memory to store the codes.
