Unless you are skilled in electrical engineering and understand the nuances of RF tuner design, you can't. A easier solution is to get an old VCR and use that as a tuner/RF modulator.
Go into the SET-UP menu then into the TUNER settings.
if your using a remote try changing the batteries
Use the remote
Use the TV remote and hit 03. Do not use the satellite remote only the TV remote.

It saves you having to walk to the television by clicking a button on the remote to change the channel or volume.
a tv remote used to change channels
I have a TV converter box, I use the remote to scan for available signals and then they are automatically programmed into my remote/system as an available viewing channel.
What kind of " Remote Control " are you talking about. If you're talking about the TV remote, it can benefit you in a wide variety of ways. Eg: You can change the channel with a touch of a button, you can go to selected channels using the number pad, you can use special settings which should be labled on your remote ect..
There is no way to change the input without a remote :(.
i need to know to no remote
Check your remote for a 'source' button. You can also keep hitting the channel down arrow until you get to the channel.
