美能达70W照相机是一款焦距为28～70mm的中档袖珍变焦照相机。它小巧玲珑,便于携带,并且功能齐全,非常适合于大多数旅游者使用。但是这种照相机也会出现各种各样的故障,其中有一个故障是比较容易发生的,即当使用了一定时间以后,照相机就怎么也不动了。除了在液晶显示屏上显示日期以外,其他任何显示和动作都没有了,这就是所谓的“死机”现象。这种情况不仅仅发生在中档袖珍照相机中,同时也发生在高档单镜头反光照相机上。凡是照相机电路中采用了单片数字计算机电路,都难免会出现这种故障。一旦出现“死机”该如何是好呢?下面我们就来详细地分析一下。
Minolta 70W camera is a focal length of 28 ~ 70mm mid-range compact zoom camera. It is small and exquisite, easy to carry, and full-featured, ideal for most travelers. However, such cameras also suffer from a variety of malfunctions. One of these malfunctions is relatively easy to happen: the camera does not move when it has been used for some time. In addition to display the date on the LCD screen, any other display and action are gone, this is the so-called “crash” phenomenon. This happens not only in mid-range pocket-sized cameras, but also in high-end single-lens reflex cameras. Any camera circuit using a single digital computer circuit, will inevitably occur this failure. Once there “crash” how to do? Here we will analyze in detail.
