Cable 3 is channel 3. Cable just indicates which tuner it is on, air (for antenna) or cable.
Samsung - 52" 1080p 120Hz Flat-Panel LCD HDTV
My cable will not work because I can't get my TV to go to channel 3 or any other channel. No matter what i do it just seems to not work. It lets me change to cable 3, cable 4 and change to different sources, but i cant figure out how to change it so its on channel 3 - does anyone have any advice?
