CIRCUIT CONCEPT FOR A TV WITH STAND-BY OPERATION

摘要

1. A circuit arrangement for a television set with low-power stand-by operation, which is equipped with a remote-controlled signal amplifier and with a remote-controlled signal amplifier and with a localcontrol unit, an evaluation circuit cooperating with the former or with both, characterized in that only the preamplifier of the of the remote-controlled signal amplifier (1) is continuously fed from a small power supply unit (4) with switch (16) closed and a voltage monitoring circuit (10) is provided which monitors the supply voltage and detects it with regard to amount in that it contains a threshold-value recognition circuit which is constructed that it only permits the switching on of the set when a certain value of the supply voltage is exceeded.
