I am currently trying to set up an Electrohome DLV1280 along with an NEC IDC-3000 scan converter connected to a DVD player. I cannot get the video to display due to unknown reasons. The projector gives me the message "unstable sync". I have checked all my connections and everything is fine. I have also tried an NEC IDC-2000 and it gives me the same thing. Anyone know what might cause this "unstable sync" problem or how to solve it??
