is 4 and 5 used over the air there?
if so its a leak.
the air signal is out of phase with the cable and you get both together which causes a ghost/screendoor effect .
common on 2/7 here in dayton.
look for bad cable open grounds bad connections ect..
or just call the cable guy out.

A friend of mine's cable reception went in the crapper, cable guy came out and found that the ground connection at the junction box on the outside of the house had gone bad. Cleaned it up and reconnected it and the signal came back sharp as ever.

no, 4 and 5 come in on cable. comcast friggin' unbelievably expensive cable, w/two ghost-y channels, and the others clean and clear. and the other TV on the same external junction box clean all the way through. if it were at the junction, every TV would have the same problem, no?
more suggestions? i and i tinkin' i don't wanna kill 1/2 a day waiting for the cable guy

well..... I have one bad feed in my house. The cable is good on 2 of the sets, on the other I get all kinds of interferrence. Try it at another connection in your house. It could just be the wire from your outlet to the set. When my set was bad, the cable guy came out and it was just the connection end on the cable. Also, try a VCR or DVD player itself (no cable hooked up) and see what your set does. If it works on Channel 3 or 4, it's your cable.....

Take a close look at every cable and connection. The cables behind the cable jacks mounted to the walls as well. Wall jacks are usually just female-female barrels mounted in a plastic faceplate. What often happens is the outer shield pulls away from the body of the F connector. You can usually push the F connector into the cable a little. The connector body has a tapered part that is to slip under the cable braid shield and outer insulation jacket. And a crimp ring that should be squashed down to force contact between the connector and shield braid. A pair of slip joint pliars will serve reasonably well to squish that crimp ring more to reestablish contact. Also check the connections at all splitters and at the grounding thingie where the cable company feed enters the house. Be sure the ground connection stays good; it protects you and your TVs if a power wire should fall and touch the cable system. This is probably what the cable guy would do. A small crescent wrench may come in handy to loosen or tighten the connectors. Use only moderate force, not all your might, on the wrench.
