yung may nakalagay na code yung number sa tapat nun ang input mo din sa remote mo, sometimes madaming codes for apartcular brand and device, example LG Tv may have 5 different codes, yuo must try to input everything until you get the code that will work,
in your illustration, you need to input 10556 as code but if it will not work, there is another code 10556(1/2), im sure there is an option to check the other code.
when programming the TV, press the button that says TV in your remote and follow the rest of the instructions
