Abstract

티브이의 파워 오프시 남게되는 음극선관의 잔류 고압에 따른 스트레이 메이션을 방지하기 위하여, 파워 온시자체의 릴레이 접점은 오픈시키고 파워 오프시 클로우즈 시키기 위한 제1릴레이부와, 파워 온 시 전하를 충전하고 파워 오프시 방전하기위한 충방전부, 음극선관의 고압측과 접지라인 사이에 접속된 릴레이 접점을 갖고 파워 오프시 충방전부의 방전 전압에 의해 이 릴레이 접점을 접점을 클로우즈시키는 제2릴레이부를 포함하여 음극선관의 스트레이 메이션 방지회로를 구성한다.In order to prevent the deformation caused by the residual high voltage of the cathode ray tube remaining during the power-off of the TV, a first relay unit for opening the relay contact of the power-on itself and closing the power-off and charging the electric power at the time of power-on Cathode ray tube including a charging and discharging portion for discharging when off, a second relay portion having a relay contact connected between the high voltage side of the cathode ray tube and a ground line and closing the relay contact with the discharge voltage of the charging and discharging portion at power off. Constitutes a strain prevention circuit.
