Removing The Amplifier PCB (DP1000)
Before beginning any service work, remove all power to the unit and disconnect any signal cables where
necessary. Adopt static electricity working procedures when carrying out service work. Ensure
adequate lighting and use the correct tools. Access to the Amplifier circuit board can only be achieved
once the console has been opened (see ‘Opening up the DP1000 console’).
1)
Turn the base onto its side (supporting if necessary) to reveal underside. Referring to fig.7
remove the 5 screws from the base.
2)
Place the unit so that it is upright again. Referring to fig.7 remove the 4 heat-sink screws from
the side of the console.
3)
Using Long-nose pliers, squeeze the joining pillar in the Amplifier PCB (see fig.8) to release it
from the PCB.
