I have the radio volume all the way up...the TV tuned to channel 4...and the radio tuned so the speaker is quiet. We might be as low as 91MHz. No wonder this thing didn't work. I haven't done anything to the TV yet as far as messing with the channel coils. Waiting until I hear from you guys regarding the next step.

This is good.
If it is as low as 91MHz that would explain why you are getting picture and no sound. Confirm the quiet spot on the radio dial is indeed the tv oscillator by turing back and forth the fine tuning control. You should hear a change.
The screw is made of brass so that means turning the screw clockwise should bring the frequency up. However, because the inductances for all of the channels are in series, the higher channels, likely 5 or 6 may be out. I would start with turning clockwise the 4 screw. If the screw becomes tight before reaching 93MHz, let us know.
