patulong mga master samsung k1 hizzing sound lang
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?
