一台甘光JG304C型“傻瓜”相机,三年前最后一次使用时一切正常。如今拿出来再用发现闪光灯充不上电。经查闪光灯电路中的充电电容失效且漏电,更换电容后故障才排除。电子照相机的快门控制和闪光灯均采用电子电路。长期不用时应每隔几个月给电路通电保养一次。否则电路中的电容,尤其是电解电容器会容量减小甚至失效。造成不应有的损失。 A Kagyu JG304C “fool” camera, the last time three years ago when everything was normal. Now come up again and found that the flash is not charged. Check the flash circuit charging capacitor failure and leakage, replace the capacitor after troubleshooting. Electronic camera shutter control and flash are using electronic circuits. When not in use for a long time every few months to power the circuit once. Otherwise, the capacitance of the circuit, especially the electrolytic capacitor will decrease or even fail. Cause undue loss.
