I have an LG Google TV, how do I remove/disable the smart features?

So Google has long abandoned my LG Google TV, with no continuing support. However, I CONTINUE to have to wait for the OS to load and then exit out of the now worthless smart hub home screen in order to resume viewing in full screen rather than the small window afforded to the television picture when the home screen is active. Its not the end of the world, but having the extra steps and the TV being paralyzed while it boots a worthless operating system (can't switch inputs until it finishes) is a pain. All I want it to turn on the TV with normal, "dumb" tv functions. Can anyone help?
