I bought official Nintendo component cables and ran them into my Sony STR-DH810 receiver. I have an HDMI cable from the receiver to my LG 42 inch LCD. I know the cables are good because I hooked them directly to the TV and it was fine.
I know the HDMI cable is good because my satellite and Bluray run through it. I plugged the cables into the component 1 IN spot and the audio to the audio. I can hear it fine, but the screen looks like this. I have checked 4 or 5 times to make sure the cables are hooked up correctly. They are. Any ideas? Thank you.
That's what it looks like when you run a 480p image in to a 480i display. Is the receiver expecting 480i in and receiving 480p? First thing I would do it toggle the Wii's 480i/480p setting to see if one behaves properly. Then dig through your receiver's video input menu options and see if there is some sort of "Force 480i" setting, or something.
