Question about Sony FD Trinitron WEGA KV-34HS420 34" TV
Sounds like it could be a problem in the vertical sweep curcuit as if the vert sweep fails it blanks out the video and screen drive so the tubs dont get a line burnt into the face of the picture tube. Have this checked out by a pro as I doubt if you can do this repair unless your an electronic tech.. Good Luck
