filtrare tensiuni in sursa la tv lcd sharp LC-26SB25E

Recommended Posts

va salut!

de aprox.4 luni am primit acest lcd de la cineva spre reparat.defect: dungi la pornire pe panel 10 minute dupa care revenea. panel=V260B1-L11 T-CON V260B1-XC11 ...am mai discutat la viewtopic.php?f=17&t=138879.

individul a renuntat la el si-a luat un Sony...m-i la dat mie la un pret mic... am inlocuit condensatorii din sursa(715T3188-1):cei de pe bara de 24 v si 12 v care erau umflati.problema ce ma framanta pe mine este nu sta cam prost la capitolul filtrare?am vazut la alte surse cumulat la nr de condensatori ex:4000uf pe bara de 12v,4000 de uf pe 24v.nici pe placa de baza nu sunt cond. de filtrare mari ca si capacitate.intreb deoarece sunt novice in ale electronicii,mai mult un hoby. multumesc!

PE INVERTER NU SUNT FILTRAJE ?Pune osciloscopul pe cele 2 bare si te lamuresti daca's bine filtrate .

Daca fabrica l-a facut asa este ok.Cred ca conteaza si ce fel de sursa este acolo.
