TV Samsung 5013 porneste greu dupa citeva minute

Recommended Posts

Buna ziuaAm o problema cu TV samsung CK5013 , acesta nu porneste , (lipsa rastru , sunet ) decit dupa citeva minute in functie de temperatura din camera , ( cind e mai cald mai repede ) dar cind porneste functioneaza normal . Care sa fie cauza ? din schema cred ca ar fi termistorul P802 defect dar nu am parametrii pentru a procura unul nou .Va multumesc

daca are sursa cu tda 4601 ,schimba c ul de cuplaj cu bu-ul din sursa.

daca ar fi BU 508 defect nu cred ca nu ar porni dupa citeva minute , c de cuplaj este de 100 mf/16v ?
