笔者接修多台JEC LCD-288相机,故障部位都一样,成为了该款相机的一个通病。 故障现象 卷片、显示正常。但快门叶片要么不开,不能曝光,闪光灯也不闪,要么就要快门打开后关不上、关不严,造成大开门现象。 拆开相机前盖（有5颗螺丝,两颗在电池盒内,两颗在相机暗仓内,还有一颗在三脚支架螺帽内）,拨动带动叶片的电磁铁芯,感觉比较涩腻,不灵活,造成虽有曝光信号,但叶片不能开启。有时情况是拨开了叶片后反弹回不到位,形成快门大开门。问题就出在快门电磁铁上。 I then repair more than one JEC LCD-288 camera, the same fault parts, as a common problem of the camera. Fault phenomenon volume film, showed normal. But the shutter blade is either not open, can not be exposed, the flash is not flash, or shut the shutter open, the closed lax, resulting in open the door phenomenon. Open the camera front cover (there are five screws, two in the battery compartment, two in the camera darkroom, there is a three-legged stent nut), toggle the solenoid valve driven leaves, feel more astringent tired , Inflexible, resulting in exposure signal, but leaves can not be opened. Sometimes the situation is opened after the leaves bounce back is not in place to form a large open the shutter door. The problem lies in the shutter solenoid.
