Colour Duo no power

1. Check the blue LED on the external power supply. If this LED is on, the problem is further down the line. If this LED is off, contact us for a replacement power supply.
2. Check the connection between the I/O board and drawer. Make sure the drawer is completely inserted and that the thumb screws are screwed in. Power is passed to the audio circuitry through the two sets of large connectors CON1 and CON2.
3. Make sure the ACTIVE switch is in. No power will pass to the drawer when this switch is out.
