What type of remote are you using? Do you have a Nevo? Sometimes discretes are on the original remote, sometimes they're in a database in the software for a programmable remote, sometimes you get lucky and find them here on this website, sometimes they are on a manufacturer's website (hitachi plasmas are one that I can think of). Oh, btw, discretes are codes that perform one function only, not a toggle code or scroll through inputs type. No matter how many times in a row you hit a button with descretes, ie power on, the device only does one thing.
