Abstract
A switching circuit for a television set is coupled to the television microprocessor and associated power supply on one end, and to the standby power supply portion of a T-chip on the other end. The T-chip is not powered during the "off" times of the television thus reducing the power consumption of the circuit. The switching circuit operates to enable the standby power supply of the T-chip upon receipt by the microprocessor of an "on" command after which the T-chip will enable the horizontal drive circuits upon the receipt of a further "on" command.
