Monitor LCD Philips- defect

Recommended Posts

Buna seara tuturor. Am un monitor LCD PHILIPS Model : HWS8200Q (200WS8) , defect in sursa . Sursa echipata cu CI DMO565R defect, in scurt. Am inlocuit circuitul integrat cu unul nou, conectez monitorul la retea, se aude un tiuit "subtire" in chooper sursei semn ca functioneaza , dar ledul de st-by nu se aprinde daca apas pe el...Atingand usor bara de minus din secundar, se aprinde ledul de st-by se aprind lampile si totul functineaza normal, fara a se intrerupe..Daca scot cablul de retea si incarc din nou sa pornesc, aceeasi problema ..Tin sa precizez ca am inlocuit toti condensatorii din primar si din secundarul sursei...
