摘要

The television set has a synchronised switched mode power supply and a remote controller switching on and off the line output stage. In standby mode the power supply provides only the energy for the remote control receiver, evaluation of remote control signals, and the drive voltage for the horizontal drive and output stages. For the production of the drive voltages (U5, U6, U7) for all remaining stages, a respective thyristor (22, 23, 24) is provided which is controlled at its gate electrode from the line output stage (14). The evaluation of the remote control signals may be using a microprocessor.
