Default Olympus UZ2100 SDS repair

Olympus UZ 2100 camera with SDS (Sudden death syndrome)

Recently I took part in repair of a Olympus UZ 2100 camera with SDS (Sudden death syndrome).
SDS is known as a failure where the camera has problems with starting up the LCD display and controlling the zoom function (among other)

The reason for this failure was a fuse resistor in the power circuitry which was blown - the normal value is probably 0.1 Ohm.

In order to repair the camera it was necessary to take it apart almost completely - no easy way.

About 75 screws were removed - different sizes and threads - they were organized and numbered in a way so they could be mounted again correctly. Numbers were written on the camera with a thin permanent marker at all places where a screw was removed.

Before a mechanical part is removed it is a good idea to make a marking on the part itself and on the part it was removed from.

I guess the whole job took about 10 hours - but the gift was getting the wonderful UZ2100 to work again.

If you don't have some experience in electronics and delicate mechanics, it cannot be adviced to do the job.

Take care with static electricity.

The procedure was as follows:

 Start removing all outer shell parts - you need to remove all screws, also those underneath the flash when opened up and in the battery/flash card compartment.
 Protect the lens hereafter
 Remove the LCD pcb - (leave it hanging in the two thick wires). The ribbon cable connector has a release function - use it.
 Remove the top LCD pcb
 Remove the plastic parts for the battery compartment and flash card slot
 Remove the pcb behind the formerly removed LCD pcb
 Remove the total lens unit.
 The power supply pcb should now be visible (recogniced with a big capacitor and a metal shield plate on it)
 In one corner of the power supply pcb two fuse resistors can be seen with a "N" marking on the top
 One of those is probably blown - check it with an Ohm meter - the reading should be close to zero
 Either replace the fuse with a new one or short circuit the old one with a thin wire that is soldered on top of it.
 Assemble the camera again !!
 Put in batteries and pray.... we had luck with it - I guess you will also succeed with it

Payne, thank you for your informative and detailed post! I know of at least two others out there who have purchased non-working UZI's with hopes of reviving them. Perhaps you will hear from them. Even if not, this is very useful info in case we ever need to attempt the repairs ourselves. If you have the wattage rating of the resistor, that would be helpful.

Hi lg,

sorry, I don't have the wattage - but it was a SMD component (surface mounted) - I think size 0805 an probably 0.1 Ohm

Default C-2100 repair


thank you for the repair description. I tried the same, but made a terrible mistake:

When I tried to remove the flex cable connector for the top LCD and the jog dial, I did not just pull it out, but I thought the flex plug needed to be unlocked in some way. So I lifted the plug-in connector with a small srewdriver and thus broke the PCB solder connections. After that I did not have the nerve to proceed, but sent the camera to Olympus, Portugal, (via Olympus Hamburg) for repair. They charged me 338,- Euro! The first repair was useless, they fixed the SDS problem but didn't notice at all that the top LCD and the jog dial were defunct. I wonder how they do their final test.

Let me say this:

I am a professional designer of Integrated Circuits and familiar with delicate electronics. Disassembling an UZI is no box of chocolate. Sharing your repair steps is a great and noble idea, especially since Olympus charges that much for the repair of a design error they committed. But in order to prevent people from stupid judgements like mine, more detail is nescessary, I am afraid. Otherwise some broken-UZI owners may end up with even bigger frustration. Why don't you make an illustrated description and ask for a small refund? Share-Repair!

Sincerely, Herbert

Dear Herbert,

I know the repair description is made very short compared with that it took about ten hours to do it.

When we started the repair we did not think of sharing the info with others at the NG's - this is why we for instance did not take any pictures.

The main purpose with the message is to tell people that the repair actually can be done - and what the problem is/was.

I am sure a lot of people can do the same if they are careful and taking their time doing the job - but of course there is always a risk.

The reason we did the job was that it was too expensive to repair - so next stop for the camera would have been the trash bin.

The camera is assembled now and it works so it will be difficult for me to make further descriptions - the disassemble/asssemble steps would be so detailed that I would need to make the job again
