It’s time for a teardown, this time we have a Kodak EasyShare CX4200 2MP Digital Camera which was manufactured in 2002 so it’s now 11 years old!
A few screws later and we’re in.
We’ve got the top side which has the AA battery, flash and camera and bottom side which has a Casio LCD. It’s a two board construction with a small interface board just below the CCD.
Main board – top side
Altek main chip
Couldn’t really find anything on this chip, the Altek site is fairly basic.

Power board – bottom side
Not much here, there’s a Max 1000E chip in the middle which I wasn’t able to find anything on but there is a 3V battery on the top right.
Power board – top side
We’ve got the date code of 2002/38th week and we have 3 transformers for the flash, each stepping up the voltage for the flash. The capacitor is rated for 330V 160uF and after leaving the camera off for about 12 hours, the capacitor was still charged, so there’s no bleeder resistor. When I shorted it out I didn’t expect much but there was enough of a spark which surprised me and left a small mark on the small screwdriver I used.
Connector board
This board has a connector used for docking, it also contains the power on switch. Even though there are two wires of each colour, they all connect to the same point.
Lens Assembly
The lens assembly contains what looks like two motors presumably for adjusting the focus. They were connected to the main board by enamel wire.
