Roland Switchers: Troubleshooting Power Issues

1:

You can try disconnecting all cables, and try powering it on in another room's outlet (different circuit) with nothing connected

 

This will tell whether the issue is with either: some connected equipment, the Roland power supply, or the V-1HD+ itself

 

2:

You can also try a different power supply to see if the issue is the Roland power supply.

 

Here are the specs for the Roland power supply. You need to use a supply that is 12-17 volts that outputs 25.2 or more watts, with a connector that fits and matches the below specs

 

PSB-7U

DC Output: 12V 4A

(48 W max output, Volts x Amps = Watts)

DC Jack Diameter: 5.5mm OD 2.5mm ID

Polarity: Center Positive
