Plug in the wii system and everything comes in black and white

i think your problem is with cabling your surround sound is audio only and you wii is video and audio. i would hook up wii first and get it working first. dont plug the surround into the yellow jack on your audio video switch
good luck

To play the game you need to hook up three main things.

• First plug in the RCA cables (red, yellow, white) to its corresponding jack on the wii and colors on the TV
• Then plug in the sensor bar into the wii and place it either above or below the TV
• Lastly hook up the power into the wii and the power outlet.

Power it up and play!

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!

This sounds like bad cables on the wii, If it only happens when you plug in the wii, and your tv is ok when you unplug it , it's the wii

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.

I found a better way and it works fine. I have a new 32 inch Emerson, with only one composit hood up ( which won't work with the wii) 2 HDMI's ( again does not hook up to the wii, the monitor hook up for PC, red and white ( yellow plus is not there it's for a stereo they told me), and the usb hook up ( which is more for pictures I was told by the company).The answer was to hook my RCA plus to the red and white under the composite, then hook the yellow into the green plug of the composite, and behold- my will now works fine.

either your Wii or your TV dont match, one will be PAL and one will be NTSC or vice versa.
if you have a HD TV buy an HD composite cable off ebay for about £4 and it should sort it.

I bought a wii a few days ago and like everybody else mine too was in black and white with a grainy picture. I have a Panasonic lcd flat screen and thought I had connected it corrected, I got somebody out to have a look at it and found out there are some connections on the side of the TV which I hadn't even noticed before, once I put the red white and yellow leads in these and set the TV to AV3 everything is in perfect colour. Hope this works for some of you.

i put the wii on, powers up but i get a total black screen. wiimote does not connect either. what can i do to resolve this?
i have already disconnected all wires and connections, left it off for hours and tried putting it on again. no change. Black screen still remains. HELPPPP

 Dear friend try to change your cables if you are using regular A/V cables, you know the white/red/yellow, use a S-video cable and or maybe try to change the Video Input settings in your TV by going in the setup menu and look for the settings that will suit your console the best, most TVs comes with adjustable Video settings that ranges from Normal, Theater or Cinema, Video Game etc. pick the one that works with your systems. If none of this works try to contact the place you bought the TV and ask them for warranty repair or exchange. good luck!
