I assume you both have the original remote for the TV. What kind of universal remote do you have? That apparently can use "codes" in some PC transferable form, but can't learn from the original remote?

I you have any learned codes in any form that can be uploaded to a PC, I probably can help you figure out missing signals and/or translate those signals to some other form.

Do you have any specs on that "switch controlled remote device" that might explain what form of codes it needs?
