Zeitaufwand

15 - 30 Minuten

Einleitung

If the camera powers on but does not function properly (refuses to take pictures, fails to navigate the memory card, prevents access to settings, etc.), you may need to replace the motherboard.

Werkzeuge

Schritt 1

Use your finger to push the notch of the compartment door to the center of the camera body.
Release the compartment door, and it will swing open.
Remove the existing battery with your fingers.

Schritt 2

Use a Phillips #000 Precision Screwdriver for all of the following steps.
Remove both 4.5 mm screws holding the bottom into place.
Remove both 4.5 mm screws holding the side into place.
Remove the 4.5 mm screw underneath the A/V flap.
Remove the 4.0 mm screw on the left-side wrist strap loop.

Schritt 3

Carefully lift the back cover from the camera.
Do NOT completely remove the back cover from the camera yet. There is a data transfer ribbon connecting the LCD screen to the motherboard.

Schritt 4

Press your finger on the top of the latch and pull it down and towards you to open the safety latch and free the ribbon.
Be careful when releasing the safety latch because it is fragile and may break easily.
Slide the ribbon out from its socket.
It is now safe to completely remove the back cover from the camera.

Schritt 10

Desolder the wires to fully disconnect the motherboard from the camera.

By the way on step 10, you show the soldering iron right beside the "RD" red wire near top middle which should be discharged before you get the shitfuckpiss scared out of you and drop your soldering iron in your lap. There's gotta be several thousand volts on that connection, I discharged it with alligator clips to ground after going through my fingers a couple times (before finding which one it was) about 6 times and it was extremely bright and loud. PS. My arm is numb at least to my elbows on this one! ...and I might need a new pair of pants, from either the $@$*, !#^&, or soldering iron. :(
