xbox problem

can anyone help when i turned on my xbox start screen was black&white not green.

are games b&w or just the screen? sounds like your settings got messed or you could have tried to change skins? you didn't provide enough information on the problem

 

do you have a modded xbox? a lil more info would be nice i agree.

 

sorry for the lack of information regarding my xbox.
and thank u for the response regarding this matter.
but i have found what the problem was. it was the lead that connects to the av con.
