Sursa cu STR-S6707

Recommended Posts

Sanatate permanenta!TV Goldstar sasiu MC 41B.Dupa un timp(ore sau chiar o zi) dispare imaginea,sonor OK,asa mi-a spus omul..Am gasit C-urile de pe +112V rele si le-am schimbat.Am pus altele noi pe spatele placii si l-am lasat sa functioneze  cam 18 ore totul OK apoi le-am montat cum trebuie si s-a intamplat asa:LED-ul de st-by se aprinde/stinge ritmic ,Am schimbat toti condensatorii din sursa(primar secundar),la fel.Pe bec porneste doar daca o alimentez si apoi cuplez sarcina,odata ce o ia face ON/OFF.In afara de optocuplor si  SE110N(nu le am momentan) tot verificat.Va rog un sfat,multam!Si lipiturile din zona STR refacute.

Mare ciudatenie!De-aseara de cand am scris n-am mai atins placa.Inainte s-o montez in TV zic sa-i mai fac o proba.Cu becul legat pe +112(acelasi bec 60W) a pornit frumos din prima,intai in st-by apoi din butoane sau TC ON-OFF toate bune.Am pus-o in TV totul OK,acum astept sa vad ce si cum.Am verificat si relipit traseul de alimentare al filamentului asa cum m-a sfatuit d-l Dan.
