Can anyone offer me advice on the following fault please? I have a Denon UD-M30 CD/ Radio receiver. When the mains is applied the On-Standby switch seems to work OK in that it changes from red to green when pressed and vice-versa. However, the display panel doesn't light up and no controls work. A possible power supply fault maybe but any advice would be appreciated. As a last resort does anyone have access to circuit diagram etc.?
Many thanks.
Gary
