Hello! I poured tea on the poppy beech air, it makes noise from the right speaker, clicks, makes a click, as if with an electric current, took it to the service, it didn’t help (they repaired the mainboard, it says they made a comprehensive repair of the mainboard) in the evening, after the repair, the problem returned! With what it can be connected? And what to do? There is a guarantee from the service, I gave 32000 there (and is it fixable at all?
