CONSTITUTION:A power source switch SW of a relay circuit RY is inserted into a first power source loop circuit A for rectifying an AC power source and supplying a comparatively high DC power source, a second power source loop circuit B for rectifying the AC power source, obtaining a comparatively low DC power source and supplying a power source for a microcomputer is provided, and by an output from the microcomputer 4, the relay circuit RY is controlled. In such a state, a protecting circuit 5 for inhibiting an operation of the relay circuit RY at the time when a voltage obtained in a second power source loop circuit B becomes abnormally high is provided. As for this protecting circuit 5, it will suffice that it is constituted so that for instance, when the voltage is abnormal, an output from the microcomputer 4 is dropped to '0' volt. In such a way, the circuit can be manufactured by quick responsiveness and at a low cost.

Abstract: PURPOSE:To visually reduce the deterioration of picture quality caused by a white dot noise generated at the time of a weak signal. CONSTITUTION:An intermediate frequency signal from a tuner 2 is provided for an amplifier circuit 3 to be amplified and detection-processed. A video signal from the amplifier circuit 3 is provided for a processing circuit 4 and a primary color signal from the processing circuit 4 is provided for an image receiving tube 5 to display an image. AGC voltage VAGC from the amplifier circuit 3 is provided for the tuner 3 to AGC-control it. The output terminal of the AGC voltage VAGC of the amplifier 3 is connected to the slider of a volume control 6 for brightness adjustment through the series circuit of a diode 10 and a resistor 11. At the time of the weak signal strength. The AGC voltage VAGC becomes not more than threshold voltage, the diode 10 is conducted, the level of a brightness adjustment signal provided for the processing circuit 4 is deteriorated and the average luminance (the level of brightness) of an image is deteriorated. Thus, the brightness of the white peak of a while noise is reduced to make the visual influence by the noise small to reduce the deterioration of the picture quality.

Abstract: PURPOSE:To output a inputted at present automatically without operating a switching device by providing a signal presence discrimination circuit to each of two external input terminals or over and selecting automatically an external input terminal whose presence of signal is discriminated. CONSTITUTION:A changeover device A has a terminal t1 receiving a main video signal and plural (3) external input terminals t2-t4 and an output of a television tuner 1 is led to the terminal t1 as a main video signal and video outputs (1)B1-(3)B3 are led respectively to three external input terminals t2-t4 as external video signals respectively. Moreover, signal presence discrimination circuits D1-D3 are provided respectively to the external input terminals t2-t4. When a video (1), e.g. is led to one of the three external input terminals t2-t4, the signal presence discrimination circuit D1 leading to the external input terminal t2 discriminates the signal presence and the external input terminal t2 is selected automatically. Thus, the video signal inputted at present is automatically outputted without selecting the video signal inputted at present from the plural external input terminals t2-t4 by the user.

Abstract: PURPOSE:To improve S/N in a variable line output terminal by controlling the output level obtained in the variable line output terminal after an insulating photocoupler by a sound volume control means. CONSTITUTION:With respect to a television receiver having a hot chassis provided with variable line output terminals 11 and 12 of an audio signal, output levels obtained in variable line output terminals 11 and 12 after insulating photocouplers 9 and 10 are controlled by sound volume control means 5-8. In this case, output levels of photocouplers 9 and 10 are made sufficiently higher than levels of noise generated by photocouplers 9 and 10. Thus, S/N is not degraded even if output levels obtained in variable line output terminals 11 and 12 are varied, and the residual noise for an output level minimum value is reduced.
