I don't know if it's still available, but the part number for the power supply unit (complete) should be VP182900 (for the US & Canada). Check with Yamaha to see if they still stock it.

I suspect you have a power supply fault, or a problem with the regulators,etc, in the DKC (latter is less likely if you don't get anything). Check with Yamaha about a replacement power supply unit (getting hard to get hold of these days) or get an engineer to have a look at the power supply. Most of the components which usually fail in the power supply should still be available).
