I hooked up a new Zinwell ZAT-970A digital to analogue converter box and noticed that there are diagonal lines going arcross the screen from left to right: ////. (The picture is clear but the interference is about the same on all channels.) It might be called Cross-hatch interference. It is constant and the lines are about 1" apart on a 27" CRT Toshiba TV. Is this a symptom of bad coax or water infiltration, antenna age, or just a radio frequency, be it FM or another band that the outdoor combination VHF/UHF/FM antenna is receiving? It is a Radioshack RS VU-160XR. I just would like to know if anyone here has had this type of interference or knows what it might be and how to eliminate it as much as possible. Thanks.
