Model # AV-32770 this JVC TV has no picture, just a bright white horizontal line across center of picture tube. Sound is fine. Suspect transformer part # cj28212-00aj1. Previous symptons for last week (before picture went out completely) was it would work for about 1 to 5 minutes then picture would scamble and finally go to the horizontal line. With the back off, the picture completely went to the white line when this Xformer part was gently vibrated. Is there a schematic of this transformer available so I can test the continuity of the transformer taps?
