patulong mga master samsung k1 hizzing sound lang

Post by Electro on Mon Feb 02, 2015 3:03 pm

mga master. hingi sana ako ng tulong. unang sira nito ay flyback. may arching siya sa katawan niya kaya palit ng bago. nung napalitan ko na master. ay nag ok na ang tv. kaya nirelease ko na sa customer. pero kinabukasan. bumali ang unit. ngayon ay ayaw na mag oscillate. lagi na lang may hizzing sound. ok naman ang h out at r2ks. posible kayang bumigay ang flyback master? o di kaya protect itong unit?

oo master. meron 145. pinagtataka ko master pag press mo ng power para mag oscillate. mag start na siya mag hizzing. tunog na parang shorted ang secondary out. pero na check ko na. ok naman ang h out at r2ks. ano pa kaya pwede sira nito.
