I just fixed this on my TV. With the small front input board removed from the tv, solderside up and the rca jacks pointing away from you begin.Looking at the board in this position locate RCA video jack. Directly in a row are 2 comparitively large solder pads. The pad furthest from the RCA jack and closest to you has a thin trace that runs from the noted pad to a solder pad on a small surface mount component marked 750. That small trace is not making contact on the solderpad that is soldered to the RCA jack. To fix it take a small metal pic or tiny flat screwdriver and scrape away some of the PC board coating right on the trace where it meets the solder pad, and place a small solder bridge on it. Thats it put it back together and watch TV. Thanks to all the members here who post solutions. Frank
