Buna ziua , acest televizor sasiu M61 - ETC009 cu procesor TDA12072H/N1F00 la pornirea din buton se aprinde ledul de st-by , la pornirea din tc sau P+ al sasiului ledul rosu clipeste de 24 dupa care se stinge , in rest nici un semn de viata . Releul care porneste sursa principala nu se aclanseaza , sursa secundara in comutatie de st-by scoate 9 volti care sint stabilizati pt. alimentarea procesorului . Va rog sa-mi dati niste sfaturi in legatura cu acest simptom , eventual un dump , dupa parerea mea e posibil ca defectul sa provina din zona procesor - memorie .
