Abstract: PROBLEM TO BE SOLVED: To instantly and surely find out whether a light source is abnormal or a power source is abnormal by allowing a control section to receive a power source abnormal signal from the power source, when the power source is abnormal, to receive a light source abnormal signal from the light source when the light source does not light, and to instruct them to an abnormality display part to display. SOLUTION: A lamp power source 53 detects if a high voltage output is outputted when an output of high voltage should be given and transmits a lamp power source output abnormality detection signal ES to a control section 50 when the high voltage output is not outputted. A lamp 35 knows whether is lighting or not by detecting if a current flows through the lamp 35 and transmits a lamp non-lit detection signal EL, when the lamp is not lit. An abnormality display part 16 informs a user of abnormality information which is causing a lamp non-lighting or processing information on those through the control of the control section 50 when the lamp does not light.

Abstract: PURPOSE:To obtain the high voltage generating circuit in which a high voltage applied to an anode of a cathode ray tube is raises slowly even when only one system of a DC/DC converter is in use. CONSTITUTION:An output voltage V2 higher than an output voltage V3 of a DC/DC converter 3 is applied to a series regulator 4 and a power supply voltage V5 is applied to a horizontal pulse generating circuit 12 only at the rising of power. The horizontal pulse generated from the horizontal pulse generating circuit 12 is fed to a horizontal deflection output circuit 13 and a resonance pulse generated in a flyback transformer 14 is boosted to generate a high voltage. Since the voltage V5 is applied to the horizontal pulse generating circuit 12 from the series regulator 4 only at the rising of power, the high voltage rises slowly.
