Let me start this by saying I’m not very knowledgeable about this stuff, so user error could be a factor. I have a Wii connected to my Samsung LCD TV through a Pioneer receiver. It worked fine for a while, but now I get the audio but no visual. The Wii is connected to the receiver through a 3-pronged Monster component game cable and the receiver connects to the TV through a 3-pronged component cable. Has anyone had this issue? Thoughts on what I can do to fix it?
