Salutare.Am acest tv care este pe sasiu PT92.Am verificat sursa care era cu probleme si pe bec este ok.Am verificat tensiunile de 45v,16v,8v ,200v care sunt dupa pornirea televizorului.Porneste pentru circa  4 secunde de doua ori  si intra in stad-by.Daca dau din buton frontal sau telecomanda la fel.Dupa  cele circa 4 secunde pe mijlocul ecranului apare un patrat colorat.Am incercat cu placa TK si fit scoase dar la fel se manifesta.In timp  scurt am masurat tensiunile pe cadre sunt ok.
