If the TV is not "cable ready" (it would have to be more than 20 years old and not have a coax input), you MUST set your TV2 output channel to AIR and as pointed out above, a lower channel. This has been recommended more than once; have you tried it yet?
The older tuners with only twin-lead antenna inputs required that any UHF signals (those above OTA 13 or CATV 22) come in through a dedicated UHF input. It is clear that you're going to have to better familiarize yourself with the TVs features and limitations.
Does the TV require a balun (adapter) to plug a RG6 cable in?
Have you tested the new HDTV in the kitchen?
