Tv plasma Hitachi model 37PD500

Recommended Posts

In acest aparat am gasit pe alimentarea de 220v alternativ 2 rezistente puse in serie dar paralele cu un releu comandat intrerupte.Pe rezistente scrie 10ohm J 5w.Am masurat dupa ele punte redresoare(foemata din 2 diode spre +-ul unui condensator de 400v) si nu este scurt.Tv-ul s-a oprit fiind oprit in stby.As vrea cel putin schema sursei macar si ceva indicatii(pareri)despre defect.multumesc
