Help Pentax k200d has stopped autofocusing

[worthsclio]

As above really, I have had this camera for a couple of years, however the auto focus has now stopped working, I have tried a variety of lenses all to no avail.
I have also tried cleaning the contacts on both the lenses and camera body.

Has anyone come across this before?

Thanks for any help in advance

have you tried a full reset.

It could be dust on the AF sensors, they are located at the bottom of the mirror box on my Nikons, just lift the mirror as you would for cleaning the sensor and you should see an opening on the base of the mirror box, give it a couple of blasts with a rocket blower.
