Abstract
An automatic beam current limiting circuit for a color television receiver comprises means for individually monitoring the three cathode currents developed in response to the green, blue and red video drive signals. The video processing unit of the receiver is automatically adjusted in response to any one of the cathode currents exceeding a predetermined level for reducing the video drive signals to limit the excessive cathode current to the predetermined level. As a result, the individual cathode currents are limited to the predetermined level while the combined cathode currents are allowed to substantially exceed this level.
