K200D: What is missing from the shutter box?

I got this camera real cheap. It overexposes but I can use it in manual and shorten the exposure time to compensate. The original owner said a "film" at the back of the shutter box was damaged and removed. This is the first DSLR I've had my hands on so have nothing to compare it to. Anyone know what is missing and if it is cost effective to repair? Thanks.

Perhaps the coating on the sensor? That might result in strange issues, but I wouldn't think overexposure as one of them.

Not really. That's the only "Film" like stuff in there that I can think of, though.

Could be the adhesive used for dust removal. I don't see why that would need to be taken out, though.

The only picture I have found of the sensor is a video here:
K200D shutter video | Flickr - Photo Sharing!
It shows it as a more uniform color, not the blotchy appearance seen on my camera sensor. Kind of a neat slow motion video.

Eulogy seems to think it could have been a film covering the sensor and by the previous owners description, I tend to agree. I wonder if it is worth replacing the sensor?

The mirror?
Is there something loose, in the bottom-left corner?
The sensor is covered by a piece of glass (optical filter), not by some film.

Possible theory: The IR filter was removed, and it overexposes because your pictures now include IR light.

Thank you and everyone before you that answered. With the help of the slow motion video link I posted in message #6 and firing the camera at a 10 second exposure time while looking inside, I was able to determine that the "film" that was removed that the previous owner spoke of was the bottom half of the shutter. The top shutter stuck half the time and when it did it looked in good condition, but then I noticed the bottom shutter was gone. The photo I posted shows the remnant of the shutter piece in the bottom left corner. Too bad: The camera has less than 3000 exposures. Hopefully I can sell it for parts.

Does it overexpose consistently, and by an amount you can compensate for with the +/-EV control on the meter?

If so, do some calibration and you have a $0 'repair'.

I was going to say with that little piece of black sticking up in the bottom left corner that they might have torn out part of the shutter. My guess would be the shutter got touched which made it stick. Rather than have it repaired they pulled it out (the shutter leafs are quite delicate - I was able to salvage the shutter in an older samsung gx10 with some tweezer work - one of them was partially torn and overlapped the next leaf - but I could see completely wrecking it quite easily).

When my K10 shutter failed in 2009? It cost $325 CDN to replace, it would be a really tough call to replace the shutter on a K200 now(likely same as K10) given age etc.

Agreed with Lowell - if it can be compensated for and used in some scenarios using M mode that will probably have to do...hopefully the initial investment was under 3 digits.

Sold it

Bought it for $60, sold it for $55. This time it was accurately described. The camera was clean and the LCD screen was scratch free. The buyer will probably be very happy if he/she bought it for the LCD or any other of the non-damaged components.
