Buna ziua. Am acest televizor la reparat cu urmatorul defect: Releul cupleaza si dup 1-2secunde decupleaza. Am masurat tensiunile de iesire si sunt 0V toate in afara de cea de stand by care este 5V. Am schimbat toti condensatori din sursa fara rezultat. Am incalzit in zona PFC+Zona de forta a sursei si sursa porneste si tvul functioneaza perfect. Ma poate ajuta cineva cu o schema sau cu niste idei?
