Probleme sursa BN44-00214A

Recommended Posts

Buna seara!Am acest tv samsung LE26A450C2 cu sursa din titlu care nu are tensiunea de st-by 5V ci mai putin 2,6V cand este cuplat main si cu main scos are 4,6V.

Main -ul nu are nici o problema ,(am dat 5V din sursa externa si tv porneste normal.)

Am verificat conzii ,am schimbat cele din partea de st -by dar fara rezultat.Poate aveti idee ,sau poate a mai intalnit cineva acest defect.Va multumesc!

Am relipit si tranzistorul acela care creaza probleme de obicei.

Am citit si aici:
