No 19 volt voltage on regulators | The FM radio and the CD mechanics do not work because the voltage coming from a blue power resistor measuring 2.7Ω on the multimeter is missing. Tsound are 3 of these resistors on the transformer board and the third one on the side cover was burned out. | Replace the 2.7Ω fuse and you will have a voltage of 19 volts to power the regulators. | Fernando Garcia |
