Power switch for multiple operating sections of television set |
摘要 |
A television power switch for preventing a picture transient phenomenon that is normally produced when the power to the television set is turned OFF. A microcomputer is used to generate a predetermined control signal when a user operates the power switch button. A power input/output section supplies and cuts off an AC power source in response to the control signal from the microcomputer. A mode selecting section converts the mode of a chroma IC between an OSD signal mode and a TV signal mode in response to the operating state of the power input/output section. The chroma IC enters the OSD signal mode when power is turned off, thereby preventing the picture transient phenomenon to be produced.
