My DSW 4000 MicroPro Subwoofer quit working in July 2025. I searched and spoke with a Polk Audio Customer Service rep regarding who was an authorized repair center and then called them. Electronic Laboratory in Pompano Beach FL agreed to diagnose and felt confident they could make the repair. I sent the Control & Power board to them. Fast forward 8 months and having had numerous conversations with laboratory the problem appears to be in the Indigo power supply and the repair center doesn't have a copy of the Indigo schematic showing the power supply to properly troubleshoot, diagnose and complete the repair. They have a copy of the Indigo Control Board schematic. Does anyone have a copy of the Indigo Power Supply schematic for a 2008 DSW 400 MicroPro Subwoofer?
