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.
