It is possible the sound is normal. Many SMPS transformers make noise. If the sound disappears when the case is installed, it could be considered a non-issue.

After i plug the cable in to the power, i get that noise, and after power up HT 5sec i hier that sound, I see HELLO on display and just in that moment noise stop, after 2-3sec noise is get back. But if i turn the volume to the 0 (min) than noise is completly out i can't hear it. If i volume up on 1, i hear it.

so in power off or power on i hear that noise, just once time today i didn't hear anaything, but why i don't know.

What can impect on that SMPS transformers to reproduce something like that sound, bad caps, resistors ??

Is it coming from the speakers, or perhaps from the coils near the class D output coils, instead of the transformer?
