Hi,

First sorry this happened, it's always painful when a trusted, well-cared "thing" stops working.

Secondly, let me offer an expert opinion. I'm an Electrical Engineer and have designed / built lots of high-end consumer products over nearly two decades.

The only way to know for sure what is wrong is to disassemble the camera and post pictures of the circuit board -- you might find or easily see something that looks burned or damaged.

I suspect when you turned on the ultrasonic cleaning feature, the camera quickly pulled a burst of current which might have destroyed a component that was near failing after having been "stressed" by years of normal use.

If I were guessing, I'd say something like a "polyfuse" (https://en.wikipedia.org/wiki/Resettable_fuse) which are devices like a normal fuse that interrupt current flow if they become too hot, and when they cool down they let current flow again ( a self-resetting fuse ).

If you really want this camera repaired, another option might be to buy a similar model that has a damaged shutter / scratched sensor and swap the circuit board with yours.

Thank you very much for your knowgeable reply.

I am a complete ignorant as far as electronics are concerned but I was 99% convinced the damage was a result of the instruction I gave  to manually  clean the camera.

I did press the manual cleaning  button, camera did shut off.

I even tried to find online information about that manual cleaning feature in order to understand how it could have broken, damaged something inside, but I was unable to find any easy to understand info.

Thank you for your reply

You did confirm my suspicions.

Swap circuit board is not within my capabilities but at least I know where damage did happen.

The information you did provide was very valuable.

Now I will try to find trustworthy place where camera can be repaired.

Thank You.
