Canon EOS10D over exposure problems

[canondriver]

I have a Canon EOS10D and after a little bump it has started to overexpose when set in any setting except manual !

I have reset all the custom functions and the camera by doing a hard reset, i.e. taking both batteries out !  Nothing has fixed it ?

The camera is still usable but only in manual which is fine and something I am proficient at doing !

Has anyone else had this problem and managed to solve it ?

Did you try another lens?

Could you have inadvertently set the exposure compensation to increase exposure? If the problem is with the lens aperture, it would surely also affect manual mode.

The 10D was a great camera in its time, perhaps it's time to look elsewhere? I've got a 40D which I like a lot. Still an old body of course, (and therefore should be inexpensive) but it's streets ahead of the 10D in every way.

I did not change anything ! after a small bump it was like that ?

Unless you have already checked, it would make sense to see if somehow you inadvertently dialed up exposure compensation (rear control wheel), which would only impact auto exposure settings.  If not, then there may be a mechanical/electrical issue. 

Given the age of the camera, it is unlikely that a repair would be cost effective.  As mentioned above, there are used cameras available that do not cost very much and would be a significant upgrade

To get closer to solving the problem, or at the least identifying the cause, a methodical approach is necessary. It's good you have already began this by resetting the CF and an hard reset.

Hard Reset should, I believe remove Exposure Compensation, however as advised it is sensible to physically check that no EC is dialed in.

Additionally clear feedback here of test results will harness focused comments.  

If not already done this would be a good start to whittling down the issue:

1. How exactly are you measuring the over exposure?

2. Have you performed an A/B comparison capture of the same scene and same lighting, one in M Mode and one in Av Mode, Tv Mode and P Mode?

3. What is the extent of the overexposure - is it the same (in stops) for P Av and Tv relative to M Mode?

4. Is the overexposure the same across all Metering Modes?

I am going to have a tinker with all sorts of setting this weekend and see what happens.
