Monitor Quintron 17"

Recommended Posts

Salut, am un monitor marca Quintron 17", procesor-SANSING 775V1.16, memorie-24C08, sursa-DP704C, cadre-STV8172A, model-776T, sasiu-SX775V1.3, care nu mai functioneaza.LED-ul de standby nu se mai aprinde. Am verificat finalul de linii si este bun iar tensiunea care o am pe iesire (colector)=4V.Tensiunea dupa puntea de diode este de 290V.Am schimbat toti electroliticii din partea primara a sursei si simptomul persista.Am scos finalul de linii si am pus o sarcina artificiala (bec) si nu am decat 4V oscilant.Ce problema ar putea avea si unde sa verific?M-ar ajuta si o schema daca ar avea cineva.Multumesc anticipat.
