In the process of starting to trouble shoot this issue, I inadvertantly discovered the problem.

I have a dvd player which feeds an RF modulator so I can feed a 75 ohm to 300 ohm adapter to feed the antenna on the set.

I had the set running and I was about to remove the back of the set. So I disconnected the output of the RF modulater and, miracle of miracles, the picture interference disappeared. All over the air signals look just fine, using only a rabit ears antenna. I have a 75 ohm antenna switch to switch from DVD to Rabbit ears, but when I have rabbit ears switched in (to watch over the air) I will get the interference bar only if the cable from the modulator is actually connected tot he switch. If I disconnect the cable connected from the antenna switch to the modulator, and leave only the rabbit ears connected, then no interference in the off air picture.

At least there is no problem with the tv set. Don't have any idea if the interference from the modulator can be eliminated. I wonder if the signal from Our local chanel 4 vhf station, and the modulator which is set to chanel 3 may be causing some sort of interference with each other.

I am very close to the Chanel 4 tower and the signal from that station is VERY strong. Possible signal overload from chanel 4 and the chanel 3 modulator???? I guess I may have to just live with because, other than disconnecting the modulator physically, I have no idea what to do. And then to watch a dvd (as shown in the photo of the Outer limits image) there is not much else because I have to connect the modulator to feed the set with a dvd signal.
