Typical walk through guy.. Forgot something
Glad you figured it out.
I have helped a few folks ... Was in a campground some time ago where the neighbor complained about poor cable performance.. Pushed the button and "Sharp as a Tack" was the picture all of a sudden, ,Just like magic.
Was in a motor home purchased used, She could not get cable through at all, The button made no difference.. Found out the box was...... Disocnnected.
