salutare !

este marcat273j05

are cineva idee cu ce ar fi analog?

cu SG6859ATZ nu functioneaza...12 volti in secundar este oscilanta intre 4 si 8 volti

am sa schimb si otocuplor si TL431 , cu toate ca dau bine..

Va salut

Cred ca este vorba de OB2273

 Eu am avut o placa cu controlerul defect marcat 273j10, pe care l-am inlocuit cuLD5530(30R)

Cred ca este acelas controler ca la Dv.

Dupa inlocuire sursa a mers OK

Stima.

OB2273 , SG6848 , PF6005AG toate merg si sunt pin la pin

eu am pus si nu au fost probleme, numai unul din ele in loc de 12v scoate 11,5v, dar tv merge bine si asa
