A/V input issues w/ 61" DLP

[gd11s]

Help! Bought my son a Wii for Christmas. Went to hook it up and....nothing. I've tried to hook up several other components to the same A/V inputs and no dice. This means it's not the Wii that's the problem it's the inputs. These inputs were working fine before I replaced the color wheel a few months ago. Could I have done something when replacing the color wheel to affect the A/V inputs? The component inputs are working fine but the A/V inputs aren't working at all. Any insight or ideas would be greatly appreciated before I pull the back of my TV apart again. Thanks in advance.

Are you hooking up the Wii to the back of the TV or on the side pannel?
you could have accidentally unplugged the board when you replaced the Color wheel!
