Can anybody help?. bought a new console, set it up to work ok via tv, but no colour, its all in b&w
Have you got the cables connected correctly on the back of the tv? Also have you got it on the right AV channel on the TV?
Yes, as Suraj has said, make sure the cables are connected to the TV and Wii correctly. If they are, you may require support from Nintendo directly. Or it may just be your TV. Try it on another TV.
