My default cable from wii is red white yellow.my samsung t200 lcd ports are red green blue,when i connect the two the screen is black and white.do i need a new cable or is their another way?

Some newer TVs do not have the traditional "yellow" video input, known as an "AV" connection. Even without that input, you should be able to use the standard three-color Wii AV Cable that came with the system.

What to Do:

1. Look for "component" inputs on your TV. These connections have a row of five differently-colored inputs (green, blue, and red for video, white and red for audio). If you have more than one set of component inputs, it's the first set that generally works with standard AV cables. Look for a set that has a green input with yellow around it, or the word "video" just above or below it.
2. Plug the yellow end of the Wii A/V cable into this green "Y" input. Plug the white end into the audio "L" and the red into the audio "R." Leave the blue and second red holes open.


3. Turn on your Wii console and set your television to the input select being used.
4. If you are seeing the image from the Wii in black and white, try the following to get the image in color:
   • Cycle through your television's input channels (usually with the "Input Select" or "Source" button on your TV's remote control) to find the input select that has the image in color.
   • If you're only finding the image in black and white, you may need to switch the setting of the input select from a component signal to a standard AV signal. This can be done by:
     • An on screen menu option. This is often accessed by using the "Menu" button on the remote.
     • A button on the remote that switches between the standard and component signals. These can be labeled such things as "AV" or "Video."

1) The set of input (Yellow= Composite video, Red= Right channel audio, White= Left channel audio). This set of input is for composite video.

2) The set of input (Red= Red video signal, Green= Green video signal + sync, Blue= Blue signal, Red= Right channel audio, White = Left channel audio (the Red and White will be grouped close together). This set of input is used for Component video for HD signal.

You should try using composite video source (Yellow RCA jack) from DVD player and feed to the monitor and see if it works OK with all color showing that way we acn find out if it is the video source problem or the monitor video signal processing problem. Try the PS2 on the TV if it works OK also.

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

it sounds like you may be trying to plug a standard composit video cable (yellow) into a component video input (red, green, and blue)
these are actually two different connections. Most LCD tv's will have both options (sometimes there in weird different spots on the tv tho) if you don't have a standard RGB (red, white, and yellow composite video input) then you may need to purchase a component cable either at a local store or you can get one for $5 on Ebay
hope it helps!
~good luck!

I had this problem with a 'universal' console component video cable. Had a B&W Wii screen, and couldn't set the Wii to HDTV.

Spent most of an afternoon switching the Wii between LCD televisions, annoying Samsung tech support (who are a very, very good tech support system, by the way) and so on.

Took back the cable and the guy said, "Did you remember to turn the little TV/HDTV switch here?"

There IS a tiny little switch on these combo cables, right on the common point of the various console connector plugs. I switched it. It worked. All is good again. Hope so for you too.

What to do will depend on how you're connecting your Wii console to your TV.



• With the yellow, white, and red AV cables that came with your system:
  
  
  • Did you have to use the red/green/blue inputs on your TV because it doesn't have the standard (yellow) AV inputs.
  
  
  • If this is your first time hooking up the Wii console or have you moved it to another TV, Our experience shows that many times this issue can be solved by double-checking your connection and finding the correct Input Select for your TV or VCR.
  
  
  
  
• With the blue, green, white, and red component cables (sold separately):
  
  
  • Review our step-by-step Wii Component Cable to make sure the cables are properly inserted and that your TV is set to the proper input.
  
  
If you have verified the connection is correct, and are still receiving a blank or black and white screen when powering on your Wii console, then the problem is likely with the system and it will need to be repaired. Please call 1-800-255-3700

If you are using the original component cable that has the Red, White and Yellow you need to purchase a Wii Component Video Cable.This cable is compatible and will solve your problem it will have a Red,White - Red, Green, Blue that will match the component Cable input on the back of your T240 HD Monitor.

You have to option in LCD Source In-Put.All LCD Have this In-Put
Com posit-Yellow/Red/White (AV)
In LCD Select AV Mode After That Connect Yellow /Red/White as per color pin given in your LCD.
Component-Green/Blue/Red
If you have Component in put in your LCD than select from source component mode for Red/Blue/Green.

You are connecting it into the wrong input. The Wii comes with a RCA cables that should go into the Video (composite) input that has yellow, red, and white. The component input will not work with the RCA cable input. Plug your Wii into Video1 and you should get the right colors. There should be another HDMI on the side of your TV, there are inputs located both on the back and side of the TV for your convience.

If your using the component conections (red, blue, green/red, white) to connect you wii console to your lcd then check your connection making sure the red and blue is connected properly within the right inputs, red in red and blue in blue. The red connection next to the white is considered to be the right audio connection rather than the pr connection. If your using you AV or composite (red, white and yellow) cables that comes in the box make sure you connect horizontally and not vertically in its correct input.

Your LCD TV should have one of the following types of inputs:

1. Composite. This is usually a yellow jack, along with red and white jacks for audio.
   If your TV has these, which it should, then the cable that comes with the Wii will plug directly into these jacks. Plug the yellow to the yellow jack, the red to the red jack, and the white to the white jack.
2. S-Video. This is a flat black jack. There are four little holes, and one "flat" rectagular hole. There should also be a red and white jack that go along with this for audio.
   In order to connect to this input, you will need to purchase an S-Video output cable for the Wii. Most stores that sell Wiis will sell a third-party cable for this.
   This connection will give you a significantly better picture than Composite.
   S-Video does not carry audio, so you still need to plug the red plug into the red jack and the white plug into the white jack or you'll get only video and no audio!
   
3. Component video. This is a triplet of Red, Green and Blue jacks. There is usually a set of red and white jacks along with them for audio again.
   This connection will give you the best picture, and you can set your Wii to EDTV (Progressive) mode.
   To connect to this input, you will need to get the Wii Component Video cable. Most stores that sell Wiis will either sell the official Nintendo one, or a third-party cable.
   Connect the red plug to the red jack, the green plug to the green jack, and the blue plug to the blue jack. Also connect the red audio plug to the red audio jack and the white audio plug to the white audio jack.
   Be careful not to get the red audio plug confused with the red video plug!
   If you see a picture, but the colors are wrong, then you either swapped the red and blue, or you connected the red audio plug instead of the red video plug.
