ELFORUM - Forumul electronistilor

Recommended Posts

Am un monitor TV nemarcat la care sursa face figuri. Adica tiuie 2s la inceput, apoi functioneaza 10s dupa care incepe iar sa tiuie. Uneori daca o las sa tiuie 15-20s porneste iar. Am urmat sfaturile de pe aici si am schimbat toti electroliticii. Nu are CI, doar unul care ma gandesc ca e o arie de optocuplori (CNX62). Ca tranzistor de putere are un BUW11 care se vede ca a fost inlocuit, nu e original. Si mai are un tiristor BT151. Ce e de facut?

De obicei si in monitoarele in care am intervenit, sura primara scotea o tensiune de cca. 80-90v.Din ea apoi cu surse secundare se scoteau si tensiunile functie de in ce mod de lucru era comutat monitorul. Daca ai spune mai multe despre monitor(diagonala,modurile de lucru) si despre sursa(ci.,tranzistoare) si eventual ce scrie pe eticheta capacului ,poate am gasi o schema asemanatoare si am vorbi mai la obiect.
