How do I get my tv to the input 3 channel

I can't finger out how to get my mitsubishi hd tv 1080 to the input 3 channel

What do you mean 3 channel? Are you looking for a sub out or something?

Please list the exact model or specs of all devices you are working with.

You can send audio by analog(3.5mm or RCA) or digital(in many ways like HDMI/Optical/SPDIF coaxial[RCA])

If you mean channel 3 on the tuner press numeral 3 (if you do a channel scan and there is a signal on channel 3 then it will show up in the up and down channels as well).
If you mean input 3 then you would use the TV/Video button to cycle through the inputs. If you don't have the remote then try using the channel down button to go below channel 2. This sometimes will access the inputs.
