EOS100 repair / grease on shutter

Hi there
I have bought a used EOS 100 recently (I'm not sure, but I think it was
called EOS Elan in some parts of the world). Yes, I know, it's a really
old model, but I always had one of them and after they stole my second
one at a burglary recently (again!) I have seen it at this online
auction site and just had to buy it...
Unfortunately I found that there is some greasy, sticky stuff on the
shutter (seen from the back) that sometimes prevents it from opening!
Does anybody have a hint about how to get rid of that? Like I said,
it's quite sticky. No idea how it got there in the first place. I
reckon they don't use grease around there, do they?
Or is there a repair manual somewhere, maybe a "how to dismount"? Or is
there no chance of getting to the shutter anyway?
Thanks in advance
Cheers
Joa

Thanks for all the tips guys.
I think I'll try it with cleaning first. The camera was so cheap, it's
not really worth having it serviced, I'm afraid. :-(

My EOS 10 did that too. The rubber or plastic buffers in the shutter
mechanism deteriorate and go sticky, oozing onto the blades.
Cleaning the blades is a short-term solution, more will get on the
blades from the buffers. The only solution is to replace the buffers, a
job for a camera technician, preferably a Canon tech.

Normally the greasy sticky stuff is the lube found in the lens's
focusing helical, but very modern AF cameras like the EOS100 don't
use helicals for focusing because it makes the AF too slow.
If it is heavy grease I don't know what it is doing around an
electronic shutter mechanism. Possible some got there from the
film winding gears.
I would hazard a guess that something got onto the shutter blades
when the camera was open ... hamburger grease, strawberry jam,
popsicle ...
See if applying a drop of water, waiting a minute and picking up
the water with a corner of a kleenex [or very gently with a q-tip]
removes anything. Grease won't get picked up and the water will
ball on the surface, if the goo is sugar based the water will flow
out from the drop.
I am not sure how that helps you though - it would take an awful lot
of patient work to clean the shutter in this manner.
Electronic shutters are often standard drop-in items and it you may
find the camera is repairable, but it may be the repair will cost more
than another ebay Elan.
For really old cameras -see above- that are mechanical and made from
brass and glass it is possible to effect do-it-yourself repairs. Cameras
made from plastic and electronics are not very repairable and a slip
in working on the camera can be fatal. Parts are often 'snap together -
break apart' and circuit boards and wires are soldered in place and
need to be unsoldered to take the camera apart for service.
OTOH, as there is not much to lose [other than passing on the
camera on ebay] you may want to try and fix it. Repair
manuals may not be available -- Google for them. If you can
get the shutter out it may be possible to wash the goo off the
shutter blades with distilled water if the goo is water based
or lighter fluid if it is grease. You should not have to take
the shutter apart to bits and pieces.

@m79g2000cwm.googlegroups.com:
I had a similar problem with a Rebel (EOS 200? No idea what the
European designation is). It was fixed with exceedingly little trouble
with a cotton swab and a small amount of alcohol.
Remove the battery first so that there is no chance of a short, and
use the alcohol sparingly - I would suggest dipping the swab in a small
puddle of the alcohol and pressing the excess out on a dry surface,then
gently brushing against the visible areas of the substance. It should be
obvious if it is breaking the stuff down or not. Should it appear to be
working, you can use perhaps a little more alcohol and swab along the
lines of the shutter leaves, allowing a little seepage. You can also pull
out some of the cotton to make a thin wisp on the end and insert this
gently between the shutter leaves, swabbing between them to clean any
residue from the contact surfaces. They're very delicate, so be careful.
Let dry thoroughly before re-inserting the battery to test.
If alcohol doesn't seem to be doing the trick, I would try a film
cleaner first (PEC-12), then perhaps acetone, but use this very sparingly
and carefully - it's a solvent for a million different things, including
some forms of plastic. The reason I suggest these two chemicals is that
they evaporate very quickly and will not leave a moist contact inside the
camera, should they sneak in there through capillary action.
As a last resort, if it really appears to be a grease, I'd use a
degreaser, but be careful. A common one here is WD-40, which is also a
penetrating oil and *will not dry out* within the camera, so extreme care
must be taken to avoid it slipping inside. The swab you use should be
almost entirely dry, even if it takes numerous applications to clean the
whole area. I would also follow it with alcohol.
By the way, commonly, things get fouled with everyday household
fluids, which means soda, coffee, beer, and such ;-). All of these will
come off with alcohol.
Good luck!
- Al.

Re: EOS100 repair / grease on shutter

It's around 13 years old. At that age, the rubber foam that acted as a light
seal has started to fall apart. The earlier cameras made the late 1980's
such as the EOS 650 and 620 are notorius for that.
It's possible that is the problem, it's possible it is something else.
You have in IMHO several choices:
1. Get a professional to repair the camera. This will cost $75-$100 depending
upon where you live and what is wrong. If the shutter is really broken,
or someone got glue or grease on it, it could be two to three times that
price.
2. Live with it. It depends upon how bad it is and if you can tell
when you take a picture if it failed or not.
3. Try to fix it yourself. Not very likely, cleaning the blades with some
sort of cleaner such as acetone might work or it might destroy it.
4, try to get your money back. Obviously you were sold a defective
camera.
5. Give up and use it as a paperweight.
6. Sell it to a repair shop as parts.
There might be some sort of lubricant on it, but it would not be grease.
Grease would bind the blades. More likely they were coated with some
sort of slippery substance in the first place.
I don't think it would be of any help. You need specialized tools and
a lot of practice.
Next time buy from KEH.
