TV Daewoo DTH-29U3K


Recommended Posts

La acest model de TV Daewoo DTH-29U3K sasiu CP830 F am problema de EW (imaginea este ca o perna). Am verificat cam tot ce este legat de EV. Traseu de la pocesor pana la integratul de BV I301, condesatorii nepolarizati din EW, rezistentele am inlocuit chiar si integratul I301, dar fara rezultate.. Nu stiu ce sa-i mai fac. Aveti vreo sugestie?

Va Multumesc anticipat!

C418  original avea 27u l-am inlocuit cu altul, dar nu nou luat de pe alta placa are 7u. R399 este buna, bobina de EW era putin incalzita, am inlocuit-o nu chiar cu una originala de pe un sasiu CP521. Tda8358 inlocuit. Defectul se schimba in functie de continutul imaginii,  in sensul ca se amplifica sau nu. Diodele din demodulator sunt D410 si D415 sau dioda dubla D404? oricum masurate par OK.
