I have an Omega urc-06 universal remote and a Toshiba TV. I inputted the code ages ago and can use the remote for basic functions with the TV; channel up/down, volume, text etc). I now want to access the AV channel (to use with my new Xbox) and cannot seem to be able to find the right button (or there isn't one using the code I currently have the remote/tv set to). I have lost the manual and cannot enter a different code to see if that creates a button that works. Therefore, I need a) the instructions on how to input a new code and b) the right code that creates a button that allows me to access the AV channel.
