Page 37 of the owner's manual shows how you can edit the names of the channels. Pressing the channel list button on the remote will toggle these on and off, but to change the names requires going into the menu.
I own a LN46A650 the menu seems to be missing at least one feature. I've read in the manual that I can give channels a name. It is simply not there. I have the latest firmware that is on the website. I've not noticed any other things missing but will update if I find any.
Did I miss something or did it get removed? I would LOVE to be able to label a channel as ABC, CBS, Fox, etc. but even a normal TV channel number would help.
Thanks for the help in advance.
