Nonny149 Posted June 2, 2007 Share Posted June 2, 2007 In urma unor verificari de rutina am gasit defect BU808 defect.L-am inlocuit impruna cu condensatorul din baza,dupa care am constatat ca televizorul nu executa comanda st-by.aceasta manifestare era provocata de un posibil defect de serie:colectorul tranzistorului q802 nu avea contact electric. practic nu a fost lipit.dupa ce am lipit colectorul televizorul functiona normal. find vorba de un tranzistor smd defectul poate trece usor neobservat.
