Source needs to be dtv then select M and re-tune that way.

I found out how to do it myself. Instead of having "AUTO TUNE" in channels or similar like most T.V.'s in the section that says "INSTALL" for some reason, this has "APS" where it says "CHANNEL SORT". All you have to do is select "APS" and it automatically finds and tunes in the channels. Also I found somehow in the section where it says "SOURCE" it was on "TV". That was for the old analogue system, it has to be on "DTV" to show TV channels.
