Einleitung
The inside story of a compact digital camera from sony. This one belong to a friend of mine, and is actually broken, the shutter button broke.
Werkzeuge
-
-
This is the Sony DSC-H2 we are going to tear down.
-
It's a 6.0mpix, 12x optical zoom compact digital camera.
-
It served well to the point at which the shutter button fell off.
-
To tear it apart, we need a #0 Philips screwdriver only, thats very nice of you, Sony!
-
-
-
Before you disassemble any camera, remove the batteries and wait a full day to make sure the capacitor is discharged
-
Never use bare fingers or tools with metal handles near a high voltage capacitor which you are not certain its discharged!
-
-
-
For safety reasons, find a screwdriver that has a plastic, wooden or other non-conducting handle
-
The second photo shows a spark and a plasma cloud created by rapidly discharging a capacitor similar to the one in this camera. (the picture was taken at the technical university of Łódź, Poland, do not try this at home!)
-
-
-
Now, let's start the ceremony!
-
Remove the two screws at the bottom.
-
The two on the right side.
-
And the one on the left side
-
-
-
There is one more screw at the right side of the flash lamp
-
These 5 screws are identical, and unique to the outer shell of the camera.
-
We may now remove the back shell, revealing the LCD and rear control panel
-
The body is thick and looks durable
-
-
-
Remove the two philips screws, and the two ribbons.
-
The button panel and the LCD is now free.
-
The camera has a 2.0", 85,000 dot LCD
-
-
-
Under the LCD, we find a metal screen protecting the logic board.
-
Carefully unlock it at the top and left side
-
We're in
-
Remove all the ribbon cables. There sure is a lot of them.
-
Some of the ribbon cables have "Halogen free" singed on them. That's nice, but we are still not throwing the camera away, not just yet.
-
-
-
These two screws hold the logic board.
-
When removing the board, be careful about some remaining ribbon cables.
-
The board is out!
-
On one side we see the AD80080A chip from Analog devices responsible for capturing the analog signal from the CCD
-
On the other side, we see the Sony "Real Imaging Processor" that converts raw photo data into nice and human-viewable .jpg files.
-
The analog cable connecting the CCD to the logic board is screened with some pieces of metal to reduce noise.
-
-
-
Under the logic board there is this piece of plastic, separating the lens and sensor from the rest of the camera.
-
It comes right out, no screws or whatsoever.
-
Detach the electronic viewfinder atop.
-
The plastic locks hold the lens and screen of the electronic viewfinder together.
-
-
-
The viewfinder screen is sooooo smallll!
-
It has 200.000 dots, and about 30mm2 of area
-
That is some insane pixel density, look what happens when the optics used to view this display are pressed against a typical laptop display - you can see the sub-pixels!
-
-
-
The next two screws hold the lens and sensor module
-
It's out, and it's huge.
-
You can even make it bigger, apply 3 volts to the marked terminals to extend the lens.
-
-
-
Remove these two screws to detach the sensor from the lens
-
The sensor has a typical 1/2.5" size. That's not a big sensor.
-
Here you have a 5 polish zloty coin for comparison.
-
5 polish zloty's is about $1.80, in case you don't grasp the size yet :)
-
The CCD is very shinny.
-
6 megapixels from a 1 / 2.5" sensor is like expecting 70 megapixels from a 35mm film camera. It's still better then pumping 12 megapixels out of a pinhead sized sensor in mobile phones.
-
-
-
The Carl Zeiss lens from the sony camera alongside the lens from a Zorki-6 soviet compact rangefinder from 1960.
-
The back of the Zeiss has significantly more electronics, ribbon cables and servomechanisms than the Zorka lens
-
-
-
Lets get back to the body of the camera
-
Lift this plastic lock to remove the hight voltage chip powering the speed light.
-
3 cables connect this board with the lamp and they are soldered.
-
The capacitor has 320 micro farads of capacity and operates at 330 volts. That's 17.4 joules of potential electric energy, quite much for a speed light.
-
-
-
To get to the microphone and top button panel, unscrew these three.
-
Finally the button panel, with the broken shutter button.

Excellent teardown! Great job!
Do you have a Sony Cybershot DSC-H2 camera? Did your shutter button just POP OFF? Are you mad that your $400 Cybershot is now useless due to their design flaw?
Well jump on in! We're gonna do something about it. http://www.thepetitionsite.com/1/SonyCla...
Awesome tear-down, saved me $150 bucks and my camera is back!. We love this camera and are so happy to have it working again.
