DISCLAIMER

! Note: Anything you do to your camera is of your own volition. Don't come running to me if you ruin a lens / filter / camera etc.


This project in particular will invalidate any warranty you may have on your camera. If you need to do this and your camera is in warranty, get the FujiFilm Repair Department to fix it.

YOU HAVE BEEN WARNED !

Dust inside your LCD viewfinder can be a major annoyance depending upon how much has found its way there. It shows up as black specs when the camera is on and pointing at light subjects and moves around with the camera. Don't confuse this with dead pixels which are damaged pixels in the viewfinder LCD itself.

This project involves opening up your camera to clean this, which invalidates any warranty you may have. If you've a warranty left on the camera, then get the nice people in the Fuji Repair Department to give the camera viewfinder LCD a clean on your behalf (they may choose to charge you for this, but offer to extend your warranty as part of the deal - the choice is yours). Otherwise, you can open up the back of the camera and clean the dust off. It's a relatively simple task, but I've given it a 4 star rating as you'll need a steady hand and nerves of steel and have to keep an observant eye on which way around the parts are inside the viewfinder compartment). Remember - that's a few hundred pounds worth of kit you're about to get inside. If you've any doubt about opening the camera up, then back out now - it's not too late.

If you're still reading this, then I take it you're wishing to go ahead with the project - anything you break is of your own doing. Treat the camera with the gentleness and respect it deserves, it's a fine piece of delicate electronics, not a rubgy ball .

Read these instructions at least 3 times before even picking up the screwdriver. You should be fully conversant with the procedure before commencing.

Step Photos

1. First clear a good sized worksurface and gather together all your parts.

Make a loop with the sticky tape (sticky side outside) and stick it to your worksurface. This is your small screw "holder" that'll help to stop those pesky small screws slipping off the worksurface. Whenever you remove a screw, place it onto the sticky tape and it'll not be lost during your time inside the camera.

IMPORTANT: Remove the battery and any SmartMedia card inside the camera.

 

2. Next, remove the 6 screws holding the camera back on. These are located within the yellow circles on the next three diagrams (remember to put the screws onto your tape holder).




3. Now GENTLY remove the back of the camera. There is a small (approx 6cm long) white ribbon cable that connects the back buttons to the main electronics circuit board - do NOT break this, otherwise it's "camera in the bin" time. Do NOT try and unplug the ribbon cable from the circuit boards, you'll more than likely break the tabs and it's not necessary.

Once the back is opened up, you can see the LCD viewfinder unit above the main LCD monitor.

4. 4 black wires are hooked over a clip on the right hand side of the viewfinder unit. Gently unhook them (not disconnect them!) to free the unit a little more.

At this point, you will need to GENTLY wiggle the viewfinder unit out of it's compartment. A couple of wires connect the LCD at the back of the unit, DO NOT disconnect these either.

Four clips (2 on each side) hold the unit together. Use your flat blade screwdriver to unclip these and open up the unit SLOWLY. There are 4 parts inside the unit and you don't want to lose ANY of them.

5. Inside the viewfinder unit are four parts, from back to front:

1) Rear plastic protection square. Note the orientation of this as it's got a couple of angled strips that keep the LCD screen at an angle. Thickest parts at the top.

2) LCD monitor screen itself - about 1cm²

3) Concave lens |( shaped. Flat part facing the LCD monitor. Note that this has a notch out of one side. Remember which way this came out as the unit won't go back together properly it it's put back incorrectly.

4) Convex lens |) shaped. Flat part facing the LCD monitor. Again, this has a notch out of it and needs putting back in the correct way round.

 

Clean any / all parts gently and replace the parts back in the correct order / orientation.

Clip the unit top back on. If you need to force this to clip it shut, you've probably got something aligned incorrectly. Consult the diagram for help with this.

 

6. Once step 5 is complete, gently put the viewfinder unit back where it came from and re-hook the 4 black wires over the viewfinder clip on the right hand side.

Replace the back cover.

There are a couple of points worth mentioning here:

1) The left hand strap clip (looking at the back of the camera) can sometimes fall out, be sure to put it back in before closing up the camera

2) There are a couple of wires (pink and white on my camera) down by the tripod screw adapter. Make sure these don't get trapped between the back & front casing sections when closing up.

Replace all the screws, then SmartMedia and battery into your camera and switch on.

 

 

Your camera should now have a clean LCD monitor again. If the camera doesn't appear to switch on again, check the usual (flat battery / you did put the battery back in afterwards didn't you?) and open up the back again to check you've not dislodged something you shouldn't have. If the camera still doesn't switch on, you may have broken something inside the camera, in which case a professional repair is most likely necessary.

If you wish to do this project, yet don't trust yourself to not break the camera, phone a friend who you know is able to carry out the task, invite them over for a beer or two in return for them completing this project for you.
