Sursa am refacut-o.Nu sunt sigur dar ar putea fi traf linii defect?Pe traful driver nu am nici o tensiune,dar in momentul cind dau pornirea din telecomanda sau butonul de pe panou imi apare pina la 25V,dar in impulsuri.Pe bara care alimenteaza BO am 100V.Am inlocut si tranzistorul BF422 din driver dar tot asa.Am scos integratul de cadre afara si tot asa este.Un sfat ,o parere mi-ar prinde bine.Inca nu am avut proble in genul acesta.Va multumesc anticipat.

Salut. Boala veche la TV-urile Philips. Vezi ca in colectorul finalului linii ai un condensator nepolarizat ( unul mic si rotund ) in scurtcircuit. Schimba-l.

:da

 

Schema o gasesti aici:

Ai primit deja un sfat...lai pus in aplicatie?....colegul tia dat un sfat...dar ai revenit cu totul alte raspunsuri.......ai schimbat sau nu condensatorul cu pricina?
