Hi there and welcome to Just Answer. Thanks for asking your question.
What is your zipcode?
Ok. WLS (channel 7) is broadcast from the same set of towers as most of your other stations so it can't be a signal strength issue.
Can you tell me the make and model of your TV please?
Ok. Plug one of your converter boxes into the TV.
Select the correct input for the box (it will be different that when you have the cable plugged directly in, and tell me if you can see channel 7 since it will be stored in the converter box's channel memory.
Let me know.
You don't have to put it on channel 3. How is the converter box conected to the TV?
With a single 'cable' cable? Or with three RCA cables or some other method?
What I am trying to do is establish if, at the location where the new TV is located, one of the converter boxes can get Ch 7.
I know you don't have cable.
How is the converter box connected to the new TV? With a single 'cable type' cable? Or with three RCA cables or some other method?
Ok. I'm sorry this is taking a while but I'm getting there. :)
So now, does the cable box allow you to set a channel like 3 or 4 for the output?
I'm not sure that I can help you. I will opt out and other experts may be able to figure it out.
