Defect: brum puternic in difuzorul de joase.

Cauza: alimentare incorecta a circuitului integrat TDA2030.

Remediere: in acest caz, inlocuirea diodei redresoare intrerupte (tensiunea de alimentare redresata monoalternanta).

Placa electronica

Observatii: aceiasi manifestare apare si daca este defect CI sau condensatoarele de filtraj sunt uscate.
