Xbox 360 no picture and soun

I have the following problem with my xbox360 console slim, after shut it down and call again he displayed no sound or picture, league normally lights up green and shows no RL. already changed the HDMI cable with a new one and it also does not work with Component Video cable. Have tried resetting the settings of Image as suggested on the Microsoft site, and tried the console's 4 TV sets.
I wonder what the procedure to be performed on my device so I can take it up assistance for repair.
About how much would the repair?
