No matter how strong the camera is, there are weaknesses, and a camera like the Nikon D850, the king of SLR, also has a very vulnerable place, and it is often laughable to cry and laugh when something goes wrong in this place. Let's take a look at what happened to this friend.
Some time ago, a user sent a Nikon D850 for repair. According to his description, he went to the desert once before, and when he came back, he saw that there was sand and dust on the fuselage, so he cleaned the fuselage by himself, just did the fuselage cleaning, and the result was that there was a problem, and the screen was not displayed.
I took the camera and did a test, and after turning it on, the screen really didn't show up. But it's normal to take pictures, and the images on the computer are normal, so what's the problem?
I carefully observed the appearance,I found that the connection cable from the screen to the fuselage has been broken,It is estimated that when the user did the cleaning by himself,The method is wrong,Forcefully break the cable。
Users are wronged when they see the problem, which is too fragile. Recalling my own operation, I basically didn't use much force. Is there something wrong with the human brain of this design?
Why do we have to design the cable like this? Let's break it down and see why it can go wrong?
Remove the back shell and see, this is the cable. The cable is very wide, and the place where it is linked to the screen is very tight, let's imagine it. If you flip at the wrong angle, or use it too long, the cable becomes fragile and may break when touched.
To change this cable, the screen must be removed. In many places, I don't want to disassemble the screen, and if you want to replace it, you can replace it with the screen, which not only saves trouble, but also makes a profit. It costs more than 300 to change a wire (counting the maintenance fee), and more than 1000 to change a screen. Just like many car 4S shops now, selling cars does not make money, but maintenance makes money, the same reason. So now many people are reluctant to go to the 4S shop to repair the car, the cost is too high.
This is the disassembled cable set, with a new cable set on the left and a broken and damaged cable set on the right. This cable link screen has been exposed to the outside for a long time, and even if you don't touch it, it will cause problems for a long time. This is not a special material, just ordinary plastic, how long can it last?
In terms of maintenance, this is the simplest maintenance, disassemble the shell, plug in the screen cable, and install the display assembly.
Not only this camera, as long as it is a camera with a flip screen, it has the same problem, but some of them are handled more reasonably in this place, and the life is a little longer.
Finally, after installing the screen, the screen display is normal. The user was happy to see the reply. Although it cost a little money, it can be regarded as a lesson, and you should be careful when cleaning the camera in the future, at least this place should be paid special attention and not mess around.
Aperture has something to say
Every camera has a weak point, and once you touch it, it's over
For delicate instruments such as cameras and lenses, some people will not have problems using them for a lifetime. Some people can inadvertently take its life when they get it in their hands. In addition to careful protection, the method of use is also important.
In fact, many cameras have some extremely fragile places, such as the case of Sony 16-35mm that we wrote last week: "The appearance of the lens is intact, why is the internal injury serious?", many users left a message, this is a flaw in the design, and many people encounter the same problem. It's not a big deal, but it's a hassle. If you get an official repair point, not to mention the long time, the cost is not generally high. For example, the problem of this cable, most of them say that the entire screen needs to be replaced, which costs a lot of money, but in fact, it only needs to be solved by changing a cable.
Sometimes I really suspect that this is a hidden danger deliberately left by the manufacturer, a camera like Nikon D850, normal use, if you don't toss it, you can pass it on for several generations, a camera is not bad, it is not a good thing for the manufacturer, there is nothing to do with the production of a generation of machines, how to make money?
Finally, I would like to remind everyone once again that if you don't understand something, don't be a handicap, and leave professional things to professional people to do.
