Channel Selection Greyed-Out

[Acemon]

Hi,

I have an HL-R4266W. I'm trying to connect an external antenna but in the main menu the channel option is greyed-out. I know the set works with the component input, as well as HDMA and an older composite connection. I know the antenna works because I hooked it up to a smaller TV prior to installing it on my roof.

Any suggestions?

Thanks.

You are going to need the owners manual for this one, since you are going to have to go into the settings menu and "activate" the tuner input, this is veryyy common in Philips LCD TVs too.
