Philips/Magnavox TV #25TS56CI with an imaging issue. If I connect an antenna or Cox cable to the TV's ANT/CTV input the image is scrambled - with either vertical or horizontal rolls. Sound is intermittent as well (stereo, mono or none). Also, when using Cox cable and an image does appear it is in a negative format. When I connect the Cox cable to an old VCR and use RCA connections between VCR/TV the image and sound are perfect. The downside is VCR doesn't receive all of the cable channels. Any ideas/suggestions for TV repairs? Thanks.
