should be white plug and a red plug and a yellow plug . It could be plugged into component in rather than AV in . Looks almost the same the two different inputs . Component and AV. on the TV

Step 1:

Connect the audio/video input of the component cable into the "A/V" port located on the back of the xbox 360

Step 2:

Match the red, blue and green cables on the other end of the component cable to the corresponding component ports on your HDTV. If your HDTV has more than one set of component inputs, make note of which one you use.

Step 3:

Slide the switch on the component cable to "HDTV."

Step 4:

Turn on your HDTV. Set the video mode to the component port that will be used. HDTVs with multiple component ports will usually be labeled "Component 1," "Component 2" and so on

Step 5:

Turn on the Xbox 360. Go to "My Xbox." Select "System Settings" then "Console Settings" then "Display" and then "HDTV Settings." Choose the display setting (720p, 1080i and 1080p) that is best compatible with your HDTV. If you're not sure, try them all until you find the one that looks best.

Step 6:

Disconnect any previously connected A/V or component cables.

Step 7:

Connect the HDMI AV cable connector to the "HDMI AV" port on the Xbox 360.

Step 8:

Connect the other end to an available HDMI port on your HDTV. If your HDTV has more than one HDMI input, make note of which one you use.

Step 9:

Turn on your HDTV. Set the video mode to the HDMI port that will be used. HDTVs with multiple component ports will usually label them "HDMI 1," "HDMI 2" and so on.

Step 10:

Turn on the Xbox 360. Go to "My Xbox." Select "System Settings" then "Console Settings" then "Display" and then "HDTV Settings." Pick the display setting (720p, 1080i and 1080p) that looks best on your HDTV.

Are you using AV or component cables?

*Solution for AV Cable*
Check to make sure the cable is fully plugged into the port. Having it even just slightly out of the socket will render no video. If this doesn't work, try plugging it into a different port on your television to make sure the port isn't bad. If you still have no video - the video part of the cable could be bad and you might need a new cable.

Also make sure that if your cable has BOTH component and AV connections available that the switch at the end of the cable near the Xbox is set to "TV" as opposed to "HDTV"

*Solution for Component Cable*
Also check to make sure that all the video connections are fully plugged in. If even one of them isn't plugged in fully, it could render no video. Also make sure that you have them properly plugged in to the right color. If you're just quickly connecting it to the back of the TV without proper lighting, it can be easy to confuse the blue and green connections.

When using component, make sure that the switch at the end of the cable near the Xbox is set to "HDTV" as opposed to "TV".

Take it back to the store its obviously defective

some TV's have a componant button which usally means AV

hmmm

i think you must save that in service mode.if not you must find a service

If this has happened to your console it means theres ether something wrong with your AV lead
Or CONSOLE

before even considering to ring Microsoft borrow a friends wire.
if it still changes colour Call microsoft .
Probably to do with the av connectors inside the xbox
theyll fix it for free if your console is still within the warranty

pls rate.

I had a similar problem when I first connected my son's xbox using the Audio/Video cable (red, white, & yellow connectors). I connected the cable to the TV correctly, but incorrectly selected "component" as the input on the TV setup. Result was black and white display. Switch your TV input mode to "AV" or "Audio/Video" and you will get color.

FYI, "component" TV mode is only used with devices that use the red, green, & blue connectors.

x box 1 on a hdtv r u sure , or do u mean the 360?
