Dead tv. totally inoperative | Open fuse regulator ic and adjacent components burned. | Replaced the stq7011k regulator IC with a strw6053s plus a disk capacitor and a 0.32Ω resistor, the power supply turned on, but with oscillating voltages and without turning on the TV. Found a shorted 18v zener on the photo coupler line plus an SMD resistor connecting the zener to the regulator IC. I replaced the resistor with a bridge and the TV worked normally. | Paulão Tchwrma |
