greetings to the friends of the forum, I have this philips equipment fwd872 / 55, which does not have audio by radio if by cd and usb, when the radio lowers the intensity of the lighting on the display although the voltages are correct according to the diagram, the audio delivered by cd and usb is a bit distorted and spending 15 minutes more or less is normalized but without sound by radio, if any member of the forum had an experience with this team would be of great help, from now many thanks
