Samsung bn94-17423a Tv Main Pcb Assembly

Product Description

The SAMSUNG bn94-17423a is a main PCB subcon assembly designed for Samsung television sets. It manages signal processing, image rendering, and communication between internal system components. The board receives input signals from external sources, processes graphics, and coordinates functions among the tuner, HDMI, and audio circuits to maintain display accuracy. Licensed electronics technicians and TV service professionals install this board as a direct replacement when the original unit fails due to component-level damage, power surge, or system fault.

This assembly is used in Samsung flat-panel televisions where the main control board governs core display and audio functions. It integrates with the existing harness interfaces inside the main chassis to maintain stable data transfer and accurate power allocation. It is suited for residential and commercial television service applications where restoring consistent picture and sound quality is the repair objective.

Key Features

• Manages signal processing and image rendering for display output
• Coordinates communication between tuner, HDMI, and audio circuits
• Connects to chassis harness interfaces for power and data routing
• OEM-style board designed for direct drop-in replacement service
• Supports stable data transfer to maintain consistent picture and sound quality

Compatibility

Designed as an OEM-style replacement main PCB assembly for compatible Samsung television models. Verify the full model and board revision against the unit being serviced before installation.

Installation Notes

Installation should be performed by a qualified electronics technician familiar with television chassis service. Disconnect the television from AC power and allow capacitors to discharge fully before handling any internal PCB components. Handle the board by its edges to avoid electrostatic discharge damage, and use proper ESD precautions throughout the procedure. Reconnect all harness connectors fully and verify seating before restoring power.
