Can you all please help me to find the schematic of NAD VISO 1 music system?
or dose any body knows the output voltage of the power supply.where i cand buy this. no one knows? we buy them then we look at them like they were picture?

Not likely you can buy it from anywhere except if an authorised NAD service partner or distributor wants to sell you one.
I googled the service manual.
If you cannot repair (or have repaired) the power supply you could perhaps power from an external supply. Be sure it has not failed due to a fault elsewhere.
If you have access to a bench supply or even batteries you could test operation before buying a new supply (or repairing the old one).
Note the power detect connection to the mcu board. This would appear to be 2.1V.
As Nisbeth says, the power supply board would be a NAD part - if they even stock them.
I'm lucky, we have a great electronics repair shop in our village. Cost me £30 to have my mum's TV recorder psu fixed. I had looked myself first & counted 5 blown diodes, blown fuses & knowing nothing of fixing smps I thought that a bargain repair.

I'm not qualified to make psu for anybody else: If I blow myself up that's my look out.
Option 1 - use a qualified repairer to fix the faulty unit - this keeps it as original.
Option 2 - first ensure the power supply is faulty and that there are no other faults (eg blown amp causing power supply failure). Then replace the power supply. If necessary, by using an external supply.
I'd use an external 24V 120W laptop supply & hack the Viso power board as shown on attachment. This keeps the power detect functionality; without this it will not work.
Before spending the cash on a new PSU though I'd test it using any 24V supply to hand (a drill battery even).
