Minolta Dynax 800si_AF dead

Hi guys, a week ago I have bought Dynax 800SI over the internet as tested and fully operational by the words of the seller.
I was very excited to purchase this one reading the comments regarding features for the price about 40 eur.

I receive camera well packed with xi lens 28-80.

three days before film loading I was study manual for basic operations, and boom finally loaded a film and start shooting. It was a nice beggining to meet this camera.

Until yesterday, I was on 27th frame and just want to check how DOF button work, so I pressed several times.

After this, I have noticed darker viewfinder and camera is unable to AF. Green light blinks non-stop. What a dissapointment...

Now looking on the internet to try to find possible solution.

What I have find so far and what I am suspicious to is the in camera body aperture ring I guess that sits now on position on 4 o'clock and looking by the comments and pictures on camera body on the internet it should be upper on about 3 o'clock. Am I right?


Also, I have visited one near by vintage camera seller and check with another lens. Same situation with my camera body, while my lens is ok with his dynax 500 body.

Could you please help me with this one if possible?

I have removed metal ring plate with hope to see something, but witout luck. All I can see there is red wheel on the left that seems to me return this ring in lower postion and do not know how to try to check this or eventually fix this issue?

Thank you all in advance.

If you use the DOF button, it may prevent AF from working since with these any F stop slower than F8 will usually make AF unusable.

I would re-mount the lens and re press the DOF button until the aperture re-opens and then verify if AF is back working

Another thing to verify: On xi lenses, there is a way to pull on the zooming/focusing ring that disables AF. maybe you de-activated AF by accident by pressing/pulling on this ring. When you release this ring, the lens should be in AF mode again.

From this description it look that the aperture mechanism is stuck. When mounted the lens aperture must be wide open.
If it was after pressing the dof button, I would investigate if the button is locked.

Sounds similar to this problem

I also looked around the internet and found a report of someone suffering a similar problem with the older minolta 7000 camera.

He describes how he fixed the problem in the opening post but some of the following comments were revealing and it could be that the aperture control ring on the camera just needs cleaning.
