Samsung bn94-17004u Tv Main Pcb Assembly

Product Description

The SAMSUNG bn94-17004u is the primary main PCB assembly for the QAQ70F series television, functioning as the central electronic control board responsible for signal processing, content distribution, and system communication. It receives audio, video, and user input signals from connected sources and routes them to the display and audio output systems. The board interfaces with the LCD panel, power supply, input ports, wireless modules, and control circuitry to coordinate overall television operation. Licensed electronics technicians and TV service pros install this board during main board failure diagnostics and replacements.

This main PCB assembly is suited for television repair applications where the primary control board has failed or is exhibiting faults related to signal processing, source selection, smart platform performance, or system communication. It manages menu operations, input switching, smart TV features, and internal communication between electronic subsystems to restore normal performance and content streaming capability.

Installation Notes

Installation should be performed by a qualified electronics technician experienced with television board-level service. Disconnect the television from mains power and allow capacitors to discharge before handling any internal components. Handle the PCB by its edges to avoid electrostatic discharge damage to onboard components. Verify all ribbon cable and harness connections are fully seated before restoring power.
