The television had the power supply voltages all normal, but it simply left a noise like (hissing) apparently coming from the fly-back, while the post-flayback voltages were all low or insistent, (filament did not light up and 200v voltage that feeds the rbg with 130v) Important detail, the TV even in this state did not arm the protection and remained like that... | Fly-back with possible internal leakage or partial short. | Substituir o fly-back (edredom ;) | Edfesom |
