Did you NOTICE you have TWO antenna connectors on the back of the TV set?
One is for Cable and it lets you get channels 2 to 13, but nothing above 13 when you’re dealing with Over The Air Channels….
One is for AIR/UHF and it lets you get channels 2 to 69…..
That’s the one you want to connect to for all your LOCAL HD TV stations….
When you go to the autoprogram mode, select the AIR ONLY selection.
If you connect to cable and you use an outdoor/indoor antenna, the channel numbers will never be the TRUE channel numbers that you expect. That was the KEY that indicated what was occurring. Your using an antenna on the TV’s CABLE mode and not the AIR mode…
the digital tv channels will have a main, say channel 11, but there can also be a channel 11.1, 11.2 and 11.3 each can be unique. Say channel 11 is the std defintion of that channel, 11.1 might be the hd version, while 11.2 will be an all weather channel and 11.3 could news, music or whatever they might be broadcasting. 11.1, 11.2, 11.3 are all digital channels. There are also different tuners in your tv, one for analog, two for digital; atsc and qam. That’s what your tv is searching for. The reason some come in and some don’t is that depending on where your antenna is pointed will determine what signals you’ll receive. I live between two metropolitan cities and depending on which way my antenna is pointed I will get channels for one city or the other, hence why you don’t necessarily get the channels your’e supposed to. Try your antenna (use an external amplified if you want as much as you can get from your digital channels) in different locations and angles for the best reception of stations you like.
Hope that helps
