Daewoo DMQ-2075TXT

Recommended Posts

Guest Sk8eru_bv

Salutare tuturor. Am un Daewoo DMQ-2075TXT defect. Defectul a aparut dupa ce s-a ingustat imaginea si apoi nu a mai pornit (ledul rosu ramanea aprins). Am schimbat condensatorii mari, am scos tranzistorul final (ars) si cu bec de 60W am masurat U103 care era ok! Am inlocuit finalul si la pornire s-a ars rezistenta ceramica de pe sursa 10W/3,3. Desi am inlocuit-o, nu mai da niciun semn de viata. :sparge: Ma puteti ajuta sa-i dau de cap?

pai cum sa ars rezistorul de 10 w din sursa cind ai pus finalul de linii ?

ce componente are in sursa ?

eu zic sa repari susa de alimentare ,condensatori electrolitici noi,si apoi sa pui becul ca consumator ..si sa ne spui si noua ce tensiune de iesire ai masurat ..

ia vezi corespunde cu schema de aici ?
