HDMI Option on remote control

The 'source' button on my remote control no longer features the HDMI option. Formerly it gave Ext 1., followed by Ext. 2, and then HDMI - through which HD channels could be viewed. This option no longer shows and so, as such, the HD channels that I am receiving are not being viewed in HD.
Any thoughts gratefully received
