Webcam only works if the screen is almost closed

My webcam only is detected when the screen is almost closed. As soon as i open the screen fully the webcam disconnects. When it is working it works great so no issued there its obviously a simple connection issue. My question is where the webcam connection is internally so that i can check the connection. Im sure that it will be a simple fix but i dont want to open my laptop unless i know where the webcam connection is located. Hope someone can help, Thanks
