Can anyone provide me with a good source of info for setting this up, troubleshooting it, and just seeing if it's even available in Franklin, TN?
Step 1 would be to RTFM to see how to hook it up and how to scan for digital clear QAM channels. This varies widely from set to set from brand to brand.
It looks like for this set there is just a single coax input, so you can't go wrong there. Then on the menus you choose cable TV and "all" (digital and analog) then do the scan - it will take a LONG time, maybe 15 minutes.
User Jon J is correct for OTA channels - you have to let the TV scan and find them and map then to the local channel numbers. HD channel 4 is on VHF 10, for example. So when it finds a digital signal OTA on 10 it sees in the ID that it is "4.1" to that is what it displays and that is what you tune. So your TV has learned that 4.1 = HD digital VHF 10. This is not the case in a QAM tuner. If you know that channel 4 in HD is on 93.4 or than channel 8 HD is on 115.1 you should be able to tuner those up w/o scanning first. Just hit 93 prog 4 or 115 prog 1 on your remote to directly access these.
As has been covered here a 'zillion times now, the HD digital channels can be hard to get and any older/bad splitters, amps, and coax will prevent you from getting all the QAM channels locked in. If you have trouble, then wire your TV up as direct as possible to where the cable enters the house bypassing all other drops, splitters, etc. You can get a double F female and roll of RG-6 with the ends in place (in several lengths) from RadioShaft. String the coax in through the window, across the floor, whatever. Once you have all the channels coming in good, then start adding the other stuff back. You may find (as others have) that you are going to need new coax, new splitters, and maybe an amp or two.
The list of QAM channels is posted many times in this thread and I think Franklin's channels = Nashville, but I could be wrong.
