Denon 943639106050s Smps Pcb Assembly AVR-X3800H

Product Description

The DENON 943639106050s is a switched-mode power supply (SMPS) printed circuit board assembly, designed as a direct OEM replacement component for compatible Denon audio-video receivers and home theater units. The SMPS PCB is the internal power conversion board responsible for regulating and distributing DC voltage to the receiver's operating circuits. When the original board fails due to component-level faults, surge damage, or age-related degradation, this assembly provides a like-for-like replacement. Installation is typically performed by a qualified electronics technician or authorized Denon service center using appropriate ESD-safe tools and procedures.

This SMPS PCB assembly is intended for use in Denon AVR-X3800H E3 and Cinema 50 series audio-video receivers. These are multi-channel home theater receivers commonly installed in residential and light-commercial AV systems. The board is an internal sub-assembly and is not a user-serviceable part. Replacement is appropriate when a unit exhibits symptoms such as failure to power on, unexpected shutdowns, or power-rail faults confirmed through service-level diagnostics.

Key Features

• OEM Denon replacement SMPS PCB assembly for accurate power regulation and circuit compatibility
• Direct fit for AVR-X3800H E3 and Cinema 50 series receivers
• PCB sub-assembly format for complete board-level swap without component soldering
• Sourced as a genuine Denon parts and accessories item

Compatibility

Designed as an OEM replacement SMPS PCB assembly for the Denon AVR-X3800H E3 and Cinema 50 series audio-video receivers, as indicated by the part description AVRX3800HE3 CINEMA50 U.

Installation Notes

This component should be installed by a qualified electronics technician or an authorized Denon service center. Always disconnect the unit from mains power and allow capacitors to fully discharge before opening the chassis or handling internal PCB assemblies. Use ESD-safe handling practices throughout the replacement procedure to prevent damage to sensitive board components. Refer to the Denon service documentation for the applicable model before beginning disassembly.
