dan cod Posted June 18, 2012 Share Posted June 18, 2012 Ceva pe traseul care face reglajul.Trebuie sa fie un tranzistor acolo. Link to comment
naebv Posted June 19, 2012 Share Posted June 19, 2012 Verificati tranzistorii TD41,TD42 si TD43, la TDA1771. Nu este exclus ca TDA1771 sa fie cu probleme. Link to comment
