Rgb input is dissabled
If the TV has the lodgenet card installed, Which is what handles the pay per view stuff, there is no way to enable the inputs, if what they stream down from the hotel explicitly disabled the inputs. Only way around this would be to remove the 2 screws holding in the lodgenet card, and pulling it out of the back of the set (Don't have to pull it out all the way, just enough to disengage the data socket. Once the card is removed, you would need an actual LG remote (not the pay per view remote) and hit menu a bunch of times until it stops flashing menu on and off. Once it stops, you type in on the keypad, "98765" "ENTER". This will take you to an installer menu. Scrolling down to the highest numer there is (Should be one backwards from the "000" you start on" there is "Factory Reset" and you use the right arrow key and set it to "1" and then press enter. The TV will flicker a couple times, and then, all inputs are active. Once you are done with it all, pushing the lodgenet card back into it's socket, and installing the 2 screws will put the set back to the hotel settings. Now realize once that card is pulled, you won't be able to watch the hotel's PPV or inhouse channels, only a few Free to guest channels will show up.
