Abstract
A TV receiver having a metal front cabinet is provided with a discharge path between the front cabinet and a ground portion of the TV receiver. The discharge path includes a series circuit in which a discharge tube is connected in series to a parallel circuit of a first resistor and a high-voltage capacitor and a second resistor that is connected in parallel to the series circuit. The discharge path effectively discharges a voltage occurring at the front cabinet via the second resistor while preventing a sudden flow of current and reducing the influence of static electricity. The series circuit in which the discharge tube is connected in series to the parallel circuit of the first resistor and the high-voltage capacitor has a function of causing high-voltage pulses occurring at the ground portion GND to escape to the front cabinet while converting those into pulses having a low voltage level.
