How do I connect my PC VGA connection to my KLV-27HR3 TV? I have a VBA cable with blue, red & green, but I do not seem to be able to get a video input, but the sound work through another cable
Your TV have no VGA in. You could use some adapters S-video-VGA adapter but I do not garranty that it will work. Depend of Your grafic card. Red and white chinch are audio chinch and carry a sound. S video is for picture.
