An investigation was made into the temporary loss of command module color television picture by the ground station converter at Mission Control Center. Results show the picture loss was caused by a false synchronization pulse that resulted from the inability of the black level clipping circuit to respond adequately to the video signal when bright sunlight suddenly entered the camera's field of view.
