You can contact Harman Customer Support or check authorized parts distributors like JBL/Harman Parts for current stock or substitute part numbers (e.g., TPS220200-0407).
Often indicates a failure in the +/-7V standby circuit , preventing the main controller from booting the system. Troubleshooting and Repair Tips
The is a specialized switching power supply (PSU) unit primarily known for its role in high-end audio equipment, specifically within Harman Kardon active subwoofers like the HKTS 200 model . As a critical component of the internal amplifier system, it manages the conversion of mains voltage into the stable DC rails required to drive heavy bass loads. Technical Specifications and Capabilities hys3c210-cs power supply
The HYS3C210-CS is designed for high-efficiency power delivery in a compact form factor. While exact public datasheets are often proprietary to Harman, technical teardowns and repair forums reveal the following typical output configurations:
If you are comfortable with electronics, some common failure points can be addressed: You can contact Harman Customer Support or check
Like many switching power supplies, the HYS3C210-CS can degrade over time due to heat and component stress. Common issues reported by users on forums like Reddit and Elektroda include:
The subwoofer fails to turn on, often caused by a blown fuse or a failure in the primary switching MOSFET. As a critical component of the internal amplifier
Check for bulging or leaking electrolytic capacitors. Specifically, the high-voltage capacitor (e.g., 3.3µF 400V) is a known failure point that can cause the unit to stop functioning.
Finding a direct retail replacement for the HYS3C210-CS can be difficult, as it is often sold as a "service-only" part.
Always discharge large capacitors before handling the board. These components can hold a lethal charge (up to 400V) even after the unit is unplugged. Replacement and Support
