Simply scan through all of the codes to find your TV set, and in a matter of minutes—and this demonstrates the modern miracle that is electronics—you will still not have the functionality you had with your original remote. I did lose all use of the closed-captioning system, but the power, channel, and volume buttons seemed to work.
