i am using the calrad 40-7110 balun kit to extend component video from a dvd player to an new LG 42" lcd display. The run is about 75 feet. after the initial connections were made i was able to receive a signal and had video on the display. The next day the display was showing an "invalid format" icon and i have not been able to get the image back. i tried using different baluns that work on another display and i get same result. i then brought the dvd player to the room, used the baluns with a pre-made cable and it worked, i received the video. i was thinking it was a cable issue and re-terminated the ends several times with no change. what boggles me is that it worked one day and then not the next. Any Ideas?
