Comment(by Quozl):

 The four-wire cable acts as an antenna, injecting electrical noise into
 the video signals.  The amount and nature of the noise will depend on the
 ambient radiofrequency environment, and the relationship to the wavelength
 of the antenna.  Disconnect the ''cable'' from the laptop PCB before
 testing the camera.
