Polk DSW Pro 660WI blowing fuses

Hello, I am hoping someone out there has a schematic for this unit. It came in for repair because it was blowing fuses. The CQ1565RT in the power supply blew up spectacularly. I am pretty sure this is not just an issue with this part, but the result of problem on the amplifier board. Not sure if anyone has experienced this problem before, but if you did, would love to find out what the cause was. Again, if anyone has a schematic and could send it to me, I would greatly appreciate it.
