Wii is in black and white rather than color on Samsung?

I think you need to check the color settings on your new LG TV and ensure all cables are securely connected. If the issue persists, you don't have further options except to contact LG support for assistance.

Make sure that you have switched the Wii to component video in the system setting menus. Once you have done that, you should have a color picture in 480p! Hope this helps!

Have you changed the format of the TV to games or whatever input you have connected the Wii to?

a 3D tv is another form of an HD TV, you need the Wii HD cable to play it right, and make sure you plug it into the HD ports on the TV to get the color and sound back.

Your problem may be that you need to select the "AV" input on the HDTV. Samsung HDTVs of late combine the composite video with the green input component video. To use the yellow composite video in the green input port you have to select the proper AV input on the TV which tells the TV to go composite video (yellow) instead of component video (green). Try this, it may work.

mabye dumb answear did you choose right channel?
atleast at my tv in one channel my wii is black and white and a other one in color.

i have this same problem...have you found a solution?

The only way I was able to get around this was to plug into use component 1 then plug the yellow into the green on the far right. The problem I now have is that I can only use component 1. When I plug a dvd or wii into component 2, it shows still shows up in black & white, even when I plug the yellow into the green. I am not a happy Samsung owner.
