Hi, i moved my xbox from one side of a shelf to the other. same HDMI wire nothing else different. I turn on my PS3 (i know sorry) later and no picture. So i try my Bluray again no picture. as soon as i take the HDMI out of the xbox blam they both work. the xbox will not display any picture with any of the HDMI wires in any of the different ports on the TV. I then took the power brick out of the xbox and the same thing still happens, HDMI lead in xbox (no power source) no picture on the other devices. Lead pulled out of xbox and pictures are back for other devices. This is proper wierd and cant think what i might have done or how to fix this. any help would be greatly appreiciated.
