Introduction

This guide will show users how to remove and replace the lens unit if the unit is malfunctioning or damaged.

Tools

Step 1

Remove 8 screws securing outside shell. Screw locations can be found in pictures
Place Screws on magnetic surface or location where they will not roll away

Step 2

Rotate camera such that battery door is facing upwards
Squeeze area where fingers are located with thumb and remove outside shell.

Step 3

After removing you see a few wires and a screen placed on top of the circuit board looking similar to the first picture. If you don't, you might have not taken apart the wrong camera, yikes!
The second picture outlines where you can locate all the surface screws. Note that these will not be the only screws needed to be taken off to remove the circuit board.
As shown in the third picture be careful when removing the screw hidden behind the circuit.

Step 4

After removing two screws holding screen down flip screen over gently.
Remove three screws underneath screen as shown in pictures

Step 5

Using tweezers, pinch white portion of circuit as shown in picture and twist upwards. This should loosen the circuit itself.
Using tweezers, gently remove circuit from white plastic attachment.
Flip screen over and remove top most circuit closest to power button using same method.

Step 6

Be very cautious when using a soldering iron for the next couple steps (they are on average 300 F)
Using a soldering iron, remove solder from each circled location in each image to remove corresponding wires

Step 7

Using soldering iron, melt away solder and warm up metal located at top of circuit board as shown in picture
Repeat step two to three times until board feels flexible to bend

I cannot find the metal bar to heat uo. The back case feels fairly loose but does not come off. Is there another approach? Maybe the back case comes off also to allow access to the board and lens unit. Any advise?

Remove third screw attached to orange circuit ribbon as shown in third picture.

Step 10

Using screwdriver, remove silver metal piece located in center of camera.

Gently remove top portion of lens as shown in the third picture.
