enectromess:
Seems to be solved. Opened and washed main board with Isopropyl alcohol, recalibrated and a break-in of eight hours always on.  :-+
Seems to be ok. I appreciated the cleanliness and assembly of the components on pcb. Not expensive but really well contructed.  :-+

Piton:
Interestingly, maybe in my situation it is worth washing the board, especially since there is a suitable moment - I will change the encoder.

Erikkssen:
Greetings, note that in oscilloscope mainboard there are no electrolytic capacitors. Instead there are tantalum polymer capacitors. Someone says that those are not so reliable as electrolytics.  :-BROKE  (compare with keysigh teardown and others)

Who says that?

Electrolytics are almost guaranteed to dry up with age, those are probably more reliable.

DragonTHB:
Hello,

i am a little confused.

The input can messure up to 300v.
The probe can 1:1 and 1:10.

Can i messure 3kv with this RIGOL or just 300V ??
Because the instruction says the Probe can just 300 volts ?
