Buna ziua!Acest tv are placa de baza T2P03(00) si ledul rosu clipeste.Am gasit un condensator umflat in secundar pe care l-am inlocuit pe bata de 110V.47uf/160V.Dar tensiunea pe el acum este de 10V,nu are BU dus am taiat placa spre colectorul lui BU.Am mai gasit rezistenta de 150K in primar care alimenteaza ci oscilator marit valoarea la 170K.Si l-am schimbat.In secundar mai apare tensiune de 3.V si 5V pe eeprom nimic.Ira cel de 3v alimenteza un stabilizator de 5V.normal ca nu merge.Am schimbat conzii din primar 47uf /50v amandoua dar tensiunile nu urca si nu stiu de ce.Optocuplor nu are.Schema nu am si eventual astept idei ce poate fi?Va multumesc.
