Video pass thorough issue with new TV

Hay everybody, I'm having an issue with the video pass through on a Marantz 8400. I'm using the component connection to pass through the Wii signals since the Wii's component cable does not let you separate the audio and the video. It has always worked great, but with a new TV it is showing slight blurriness that is completely not there when I connect the wii directly to the TV.

I have eliminated the possibility of cables being an issue by using 3 different sets.

Just so you know my TV is a brand new replacement TV. Mitsubishi agreed that their samsung LCD panel's were defective and gave me a whole new TV after a year and a half

There is not much configuration on the TV side. It automatically senses active signals coming from each input and let's you assign a component to the input (DVD, Bluray, cable, wii, ps3 etc.) and assigns a coloring scheme which you can configure.

Any ideas?
