#1 Soundbar HW-K360 - szumi, trzeszczy subwoofer

Witam,
posiadam problem z subwooferem od zestawu Soundbar K360 + Subwoofer HW-K360.
Sprawdzane na kilku zasilaczach.
Subwoofer trzeszczy, skrzeczy po podaniu źródła sygnału na soundbar (sam soundbar działa dobrze prócz tego,żę zawsze po włączeniu jest ściszony).
Aktualizacja oprogramowania nic nie dała.


Oznaczenie kodowe płyty subwoofera:
HW_K360_SUB
CODE: AH41-01839A
MODEL: AH41-01839
SIZE: 85x85mm/1.6T
DATE: 2016.01.13

Co może być przyczyną ? Co zmierzyć lub sprawdzić na płycie głównej subwoofera ?
Załączam zdjęcia płyty subwoofera.
Kondensator C312 wygląda podejrzanie, może być winny zamieszania ? Nie znam jego wartości.

Faktycznie wygląda podejrzanie. Można zmierzyć czy nie robi zwarcia i jak ma pojemność a najlepiej podmienić. Należałoby tez pomierzyć napięcia na elkach.
