My Toshiba TV works fine with the exception of the RCA plug for video. Sound comes in fine but the Video is non-existant. It looks like the UHF VHF and RCA plugs can all be replaced with a single part but I can not seem to find the part. Can yo help me find it? The number on the back of the part I am looking at is PCL-TLC-3-V-0. It has little plug adaptors on the main TV processor board.
