invertor QPWBGL987IDLF3

Recommended Posts

E primul ccfl invertor pe care il diagnostichez asa ca aveti rabdare cu mine daca spun prostii.

 

Poza Posted Image

 

Condensatorul galben in poza de 150nF/100V e impuscat. E condensatorul paralel cu infasurarea primara.

Siguranta e arsa.

Tranzistorii par ok. Adica nu sunt in scurt.

Infasurarea de feed-back e in scurt <0,1R.

 

Se mai poate face ceva sau e transformatorul dus ?

Pe transformator scrie "YST - 1914i".Poate cineva sa-mi zica ce fel de transformator e? Eu am banuit ca e "normal" dar s-ar putea sa fie piezo.
