voltage and sweep chassis. voltage upward when the video signal is increased and downward when video signal is decreased. If the automatic brightness circuit is not used, and a high fixed voltage is applied at AG at greatest video signal input, the highlight brightness of the image is high; but upon decreasing the video signal, the brightness of the raster remains the same and the high voltage at HV decreases gradually until the signal is removed. Then the raster "blooms" and becomes "milky," and the high voltage at HV shoots up to its maximum, possibly causing arc-over in the system. Trad and Muniz: Theater Television System 133
