Samsung bn94-12855b Tv Main Pcb Assembly

Product Description

The SAMSUNG bn94-12855b is a main PCB assembly designed for use in Samsung flat-panel televisions within the SDC UNU7300K platform. This board serves as the central processing unit of the television, receiving incoming video and audio signals and routing them through integrated circuits to downstream components such as display drivers and sound amplifiers. It also governs the operating menu and overall system control. Replacement of this board is typically performed by qualified electronics technicians or experienced service technicians working on television circuit-level repairs.

This main PCB assembly is designed for installation within the main chassis of compatible Samsung television units. It connects to the power input ports and internal wiring harnesses of the set. The board handles core functions including image processing, audio signal management, and system-level control logic. It is intended for circuit-board-level service, not end-user replacement.

Key Features

• Central signal processing board handling both video and audio signal routing
• Interfaces with display drivers and sound amplifier stages via integrated circuits
• Mounts within the main chassis and connects to primary power input and internal wiring
• Controls on-screen menu operation and overall television system functions

Installation Notes

Installation should be performed by a qualified electronics or television service technician. Disconnect the television from AC power and allow internal capacitors to discharge before handling any internal boards. Handle the PCB by its edges to avoid electrostatic discharge damage to integrated circuits. Verify all ribbon cable and connector seating after installation before restoring power.
