Monitor lcd defect


Recommended Posts

In primul rand verifici condensatoarele electrolitice din alimentare si inverter. De obicei se observa cu ochiul liber daca sunt umflate, altfel masori cu esr-metru, sau inlocuiesti direct. Daca are susrsa externa, o desfaci si o verifici...Daca nu-si revine, sapa in partea de inverter. Refaci lipiturile si roaga-te sa nu fie probleme la vreun transformator de iesire spre backlight.Verifici componentele active in partea de inverter. Desi, daca sta aprins 5 secunde, cred ca-s bune.Pe ebay se gasesc invertoare la preturi convenabile...Bafta.
