This board handles signal routing for HDMI inputs, broadcast tuners, and user interface controls, then transmits video, audio, and command signals through integrated circuitry to drive the display and audio subsystems. It mounts in the main chassis of the TV and connects directly to the power supply board, input ports, and other internal boards. Installation and replacement are typically performed by qualified electronics or appliance repair technicians.\u003c\/p\u003e\u003cp\u003eThis main PCB assembly is suited for use in Samsung Q-series and Q80-series television models, including sets within the Q900B and Q80 product lines. It governs core system functions including image processing, on-screen menu control, and overall signal coordination across the television platform. Repair technicians working on affected units will find this board a direct replacement for the original failed or damaged component.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCentral signal processing board managing video, audio, and command routing\u003c\/li\u003e\n\u003cli\u003eCompatible with HDMI inputs, broadcast tuner signals, and user interface controls\u003c\/li\u003e\n\u003cli\u003eInterfaces with power supply board, input ports, and secondary internal boards\u003c\/li\u003e\n\u003cli\u003eSupports on-screen menu control and display command functions\u003c\/li\u003e\n\u003cli\u003eOEM-style replacement for the original factory-installed main PCB\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement main PCB assembly for Samsung Q900B and Q80 series television models as identified in the product line designation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified electronics repair technician. Disconnect the television from mains power and allow capacitors to discharge before handling any internal boards. Use proper ESD precautions when handling this PCB to prevent static damage to integrated circuitry. Reconnect all ribbon cables, harness connectors, and board-to-board connections securely before restoring power.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type\u003c\/strong\u003e: Main PCB Subcon Assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Television signal processing and system control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SAMSUNG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: bn94-17421b\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SAMSUNG","offers":[{"title":"Default Title","offer_id":51672453972274,"sku":"BN94-17421B","price":238.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3747e37e265729ab47ae993e0e383592.jpg?v=1787967660","url":"https:\/\/voomisupply.com\/products\/samsung-bn94-17421b-tv-main-pcb-assembly-q900b-q80","provider":"Voomi Supply","version":"1.0","type":"link"}
