You can get the schematics for your mixer at http://elektrotanya.com/behringer_ub1832fx.pdf/download.html

Can you describe the problem in more detail? By "most volume potentiometers", you mean the main faders? And what do you mean that they "don't work"? You mean there's no signal on those channels, or what?

I mean there are some main faders that interrupt signal coming from the synthesizer. yes there`s no signal on those channels . if sliding more times , the signal returns

So let's get this clear.

When the problem occurs, the signal stops completely, and none of the channel faders does anything, then if you slide some of the channel faders up and down a few times, the channels all come back. Is that right?

Have you tried anything else apart from sliding the faders? For example, have you tried tapping or shaking the mixer?

You need to try more experiments to get a clearer idea of the nature of the problem.
