Next, press and enter the code for Auria TVs, which can be found in the Comcast remote code list (usually a 3 or 4-digit number). Finally, press the "TV" button to save the code, and test the remote to ensure it controls the TV functions.

If you still have the original remote, you can use it to program a Logitech Harmony Remote with the 'learning' function. Logitech maintains the largest IR code library in the business, but does not have the codes for a TX-910 or its larger brother, the TX-930. It is possible that codes on file for other Onkyo receivers of that era may work with these remotes as well.

To program a Comcast remote to a Curtis Mathes LED1930A TV, you can try using the code 11756. If that doesn't work, you may also try other codes such as 10054 or 10178. For best results, consult the Comcast remote's user manual or use the code search function on the remote itself to find the correct code.
