He arrived, ran a few tests, determined it was the cable from the box at the rear of my property to my house. Replaced said cable. Problem solved. He gave me a $20.00 credit because hi was late.

The experience and problem you've described is nearly identical to the problem I alluded to in my post's last paragraph... a defective cable and two defective splitters inside and at the back yard box!
