Einleitung

The lens is the device that focuses the image seen by a camera. Because it is the only moving part, it can easily malfunction, causing blurry pictures or even a camera error.

Werkzeuge

Schritt 1

Remove the battery and SD card from the camera.

Schritt 2

Remove the three 3.8 mm screws from the underside of the camera.
Each of the screws is slightly different, so it is important that you note the original location of each screw.

Schritt 3

Remove the 3.2 mm screw from the right side of the camera.
Remove the 2.2 mm screw from the right side of the camera.
One of these screws is hidden under the USB port cover.
Lift the side panel off.
Remove the 1.8 mm screw from underneath the side panel.

Schritt 4

Remove the two 2.2 mm screws from the left side of the camera.
Lift the plate from the camera.

Schritt 5

Gently lift the rear of the case to remove it from the camera.

Schritt 6

Remove the front of the camera body.
Be sure to keep track of the rubber ring.

When removing the front, this little clear rubbery piece might fall out.

Schritt 7

Peel the navigation buttons from the button panel and set them aside.
To free the LCD display, remove the 2.9 mm screw in the top left corner.
Rotate the screen clockwise until it lifts away from the camera.
There are two ribbon cables attached to the rear of the screen. Do not try to pull the screen off at this point.

After removing the screw, there are two metal hooks overlapping. Once those are separated, it was easy to lift the display. Also, this metal bracket kept falling off.

Schritt 8

To unplug the ribbon cables, pull them straight out of their plugs. Do this gently to avoid damaging the connections.
After disconnecting both cables, pull the screen away from the camera to remove it.

During reassembly, I had to remove the button assembly to attach the large ribbon cable. I had to remove these two screws (there is a hidden ribbon cable under the button assembly, be careful)

Schritt 9

Now the photo sensor is exposed. In order to remove the ribbon cable from its port, first flip up the blue locking mechanism.
After the cable is unlocked, it easily pulls free.

Schritt 10

In order to remove the photo sensor, you will have to cut through glue and remove screws.
Use a knife to carefully slice through the glue at the tree points indicated. Try not to cut through anything but the glue to avoid damage.
WARNING: Knives are sharp. Treat them with respect.
Now remove the three .15 inch screws holding the photo sensor to the camera frame.

Schritt 11

Now you can carefully lift up the image sensor and remove it from the camera.
Be careful not to lose the three small springs or the rubber grommet that lie beneath the sensor.

Schritt 12

You have now successfully removed the image sensor.

Schritt 13

Once the image sensor is removed, turn the camera over and find the screw in the bottom right corner.
Remove this .01 inch screw to free the ribbon cables.

Schritt 14

One by one, detach the three ribbon cables from their ports.

Schritt 15

Pay special attention when removing this connector. It does not pull out like the rest of them. Instead, you must use a spudger to lift the connector vertically out of its slot.

Schritt 16

Flip the camera over again so that the rear is showing and remove the two .065 inch screws holding the flash unit in place. They should be on the left side.

Schritt 17

Now you should be able to remove the flash unit from the camera.
When removing the flash, be careful when handling the capacitor. It may contain a powerful charge. Discharge may result in damage and personal injury.
