Presonus Eureka Problems

Please, anyone who understand how mic preamps works, please help me, I’m so tired of this bug, I don’t know what to do :(

Half an year ago I bought used Presonus Eureka used it couple times, but find that somethings it just won’t work well. Signal literally disappears with crack noises and if I say something loud — it start to work again. The same with guitar input. Sometimes it work good all day long, sometimes every 2 minutes. I don’t know what to do.

I catch this moment when it happens.
I checked everything inside, I understand a bit in electronics — everything looks good, every capacitor has normal value, board looks good.
Sorry for my English, it’s not my language
