DX3700 Fault

I have an elderly Kodak DX3700 that has developed a fault.

Kodak want oodles of money before they'll even look at it. As I only
use it for photographing ebay stuff I'll probably take it apart and
see if anything obvious is amiss.

Photos taken indoors are generally OK-ish. However, if you take a
photo outdoors then the picture apears over exposed.

Does anyone have any ideas as to what could be at fault? There are no
manual settings for exposure..it's all automatic.

The camera has a light sensor on it and I'll obviously check that out.
However, I'm not sure how the exposure is actually controlled. Do
Kodak cameras generally have an electro-mechanical aperture control
(Which could be stuck?) or is it purely electronic?

Is there anything else that could be amiss?

The fault occured suddenly. I have questioned the wife and she swears
that no-one has dropped it...
