tuning options in the menu are greyed out.
After initial installation, analogue & digital chans can be tuned together by pressing & holding auto-tune button on set's control panel (bottom right). After choosing not to adjust the picture rotation, press OK to commence auto-tuning. If only analogue or digital systems need to be tuned - select appropriate mode (analogue or digital). Analogue chans can be tuned in normal way through menu (not greyed out in analogue mode). Digital chans can be tuned by pressing i+ on the remote, then selecting blue SET-UP option, & finally selecting AUTO TUNING from menu.
