puteti incerca cu un ups001...dar e mai complicat in cazul dumneavoastraca aveti nevoie de optocuplor :jytuiyu

Si eu m-am gandit la varianta asta,dar vedeti ca e mai cu...''draci" genul asta de sursa,din cauza ...DPM-ului
in tinerete aveam rabdare sa dau jos smaculde pe DPMde obicei erau defecte cele doua tranzistoare din primar q1 si q2

Am la reparat un tv Daewoo cu sasiul cp005,seara oprit in stby,dimineata pornit din tc ledul sa stins iar tv nu a mai pornit. Tensiunile furnizate de sursa sunt exact cele de stby(133v am 132v,45v am 34v, 16v am 14v,12v am 8v) LED-ul nu se aprinde iar tv nu iese din stby Am schimbat cuartul am verificat condensatori, tranzistori,am scos mem,nu se aprinde LED-ul,iar cit timp am facut masuratori am observat ca proces este f putin cald. Va rog daca a-ti mai intilnit sa -mi dati o idee .am si revista depanatorul nr26 si miine o sa incerc o pornire fortata sa vad scapa traful ce se intimpla va multumesc!!!
