Beko CIM302000 TX Electric Oven: Issues with Non-Functioning Thermostat and Abnormal Clock Behavior

I warmly welcome.

Recently, there was a strange burning smell coming out of cooking, so the oven was turned off and the food was finished in the pan.

The problem is that since then, the oven won't start.
The clock goes crazy flashing from 0:00 to the car and so on all the time, fan does not work, and so does the heater.
I turned on ... I did not find anything unequivocally when looking at the elements, except that the programmer's speaker is damaged.

Any ideas about the fault?
I suspect it is a thermostat, but my meter for a few zlotys shows nothing, not even the voltage on the thermostat ... it may be thrown away or I will have to replace the fuse in it.

Thanks for any suggestions

#update

I forgot to add that the LED diode next to the thermostat knob is not on, although it is not clearly connected to it (via a multiswitch).
The oven lamp (E14 thread was checked in the lamp) works, but it does not light up.

First, set the clock, I have an oven, which after each power failure, the clock resets and the oven does not work automatically, you do not need to set the actual hour, just set it by 1 minute so that "auto" does not blink

It's actually a clock, and I took the entire stove apart. For posterity, he adds the instruction manuals to the Beko CIM 302000 TX in the attachment.
Thank you very much.
