Nikon D50 Teardown & Review *Part 1/4* Disassembly - How it works / older Nikon DSLR quality...

http://www.fixyourcamera.org/nikon-d50 Nikon D50 Teardown & Review * Part 1/4 * Disassembly. D50 is an older Nikon DSLR, but still a good choice if you need something super cheap for a specific project. Here I'll show you how it looks inside, reasonably good quality parts, capacitor discharging etc. In this part I disassemble the camera and talk about basic repair subjects and some of the most common problems. You'll see how a mirrorbox and mainframe looks like, etc... Good thing about this model is that the outer covers are reasonably thick and good quality. It’s almost like a small tank, not that easy to destroy, within reason of course. Unlike all of the entry-level models that came out after this one. Like D40, D60, D3000 series. So as usual. I start with removing all the accessories. They are not necessary here. Then all of the covers. Discharge the flash capacitor. There is about 300 V on this capacitor it can hurt or possibly kill you. So please be careful with any camera that you’re going to disassemble. And continue with the top cover desoldering wires, and whatever is necessary. Next is the DG board, I usually call it digital board. Because there is a processor on it, memory, SD card, all the digital stuff is happening on this board. The sensor, this one is super easy, there are no washers, no springy adjustment thing here, just screws. Now the top part. Every DSLR, when you remove the covers, has 2 major parts. There is rear body or the mainframe and the front body or mirror box. All of the mechanical stuff is going on within the mirror box or front body. And most mechanical failures are within this part. So in order to remove it, I have to remove all of this other stuff first. Now the main board. This is the part that controls all the functions within your camera. For example, all or most of the buttons, it’s driving the motors, no heavy digital image processing is happening here. It’s not the same in every camera, so for example sometimes motor drivers are located somewhere else on the bottom, on a separate board or, as in case of many cheap DSLR’s, the main board is integrated together with the digital board. Okay so I got rid of this stuff so that now I can remove the mirror box. And it’s out. Now, at this point when everything is disassembled. It’s very important to be careful and not to touch some of the things here. So for example on the top there is a light meter, adjusted at the factory. If you squeeze it with your hands. You might cause some problems here and it might require adjustments. On the bottom, there is a focusing sensor, if you touch this one. The camera will have focusing problems, very likely. And again require adjustments, pretty much impossible to do at home, without tools. And again require adjustments, pretty much impossible to do at home, without tools. So this is the mirror box, and this is the mainframe that holds all of this stuff together. Let’s see what’s left here. A flash circuit with flash capacitor attached to it. The main motor, there is only one which is common for entry level DSLR’s. More expensive cameras usually have at least one more motor to drive the shutter separately. This one is not of a particularly great quality. It does fail from time to time, and has to be replaced. It’s not a difficult job and can be done without removing the mirror box. This one used to cost about US$15. I guess back in the day when Nikon used to sell parts. Now you cannot buy it from Nikon anymore, nut I just checked they are still available on eBay, so no problem.
