Introduction

The camera turned to be not weather-proof. After a day in heavy rain, enough water seeped, apparently, through the battery compartment, and it refused to turn on. Fuji service centre refused to make repairs to a camera with water damage. No other workshop was ready to do the job. So I had to do it myself.

    • Peel off leatherette on the back left side, near the LCD and the viewfinder. It reveals two screws.

    • Unscrew five screws. No need to touch the pair near the mounting hole.

  3. pVbrNPEhYEHVUoQE

    • Unscrew two screws.

    • Carefully pry off the port cover panel together with the flap cover. Try not to damage the spring.

  4. VPV1YwHCeGUvOtST

    • Unscrew these

  5. uCkc2H6FK2DIBWRw

    • Open the LCD panel

    • Unscrew two screws near the top

    • Note that they are of different length, the one near the viewfinder is longer.

    • Carefully pull the cover out. It may be held by the two blocks of thermal paste (yellow markers).

    • Pull off the white ribbon cable. Before pulling out the orange one, unlock the bar on the connector. See red markers.

    • Use a thin tip spludger to unstick rubber foam near the viewfinder that may be holding the back cover.

    • Peel off black (and one white) sticky patches that cover connectors.

    • Remember which patch goes to which spot.

    • Pull off the white ribbon cable (yellow marker)

    • Unlock and disconnect orange cables.

    • Unsolder the speaker.

  8. 4RxTNVc2CPXNSaMM

    • Unscrew four screws

    • Disconnect two ribbon cables.

    • Unsolder four wires going to the battery.

  10. pFI23dpZFknIcgFw

    • Peel off the round foam pad and all patches and reattach them to the replacement motherboard.

    • Be careful with the patch with copper foil (not on the picture), it is fragile.

  11. YNje2C4OXoMvbMSE

    • I am rather ashamed, but hey, it works!

    • My Hakko FX888D could not sufficiently heat the pads, I had to use a bigger soldering iron.

    • Connect and lock the wider cable

    • Insert the narrow cable. It is rather fiddly, you need to push it from the side with a pinzette.

  13. c6MfsmWoKqsshfOR

    • Push the board in place and under the hook.

    • Connect and lock all the numerous upper side ribbon cables.

    • Solder the speaker
