Sony MVC-CD300 washed out pictures

We have a Sony Mavica MVC-CD300. Bought when first came out several
years ago. It has always been a great camera.

But, recently it has developed problem that seems to be getting worse.

When taking pictures outdoors in daylight, the live picture looks great
in the display, but when you snap the picture, while recording the
picture in the display is washed out, overexposed. It is recorded on
the cd that way.

Indoors with and without flash the pictures are usually ok.

Have tried changing various settings but nothing clears this up.
Occasionally it take picture ok in daylight.

Any ideas?
