Buna ziua!Ca sa nu mai deschid topic nou, intreb aici:-tv WINDSOR 21F-06(Kenstar Line);-componente principale: UOC TDA 12020H/N1F00+ mem. 24C32BV=STV 9302Audio=TDA 7266(sau 7866, nu am vazut prea bine)Traf linii=BSC24-01 4004UProblema lui este urmatoarea:- la pornire se aude un ''ticait'' pe placa TK, chiar si luata jos de pe gatul tubului; am suspectat soclul, cu un altul luat de pe un tv functional se comporta la fel.Manifestarea dispare dupa decuplarea firului de G2(cond. de decuplare G2 de pe placa a fost schimbat)Sursa functioneaza, BO e ''functional'', rastru desigur ca nu are, fara U G2.Care credeti ca poate fi cauza defectului?

Tensiunile generate de sursa sunt corecte, tensiuni recuperate la fel; U G2 e reglabila atata timp cat firul e scos de pe placa tkE posibil sa fie de vina placa (modulul final video), am observat ''afumaturi'' in zona, si poate strapunge in tensiune(sau care e expresia corecta?)
