Samsung Television QN65Q80BAFXZA Parts

This Main PCB is the primary control board that runs the TV's main functions and interfaces with the display, audio, and input ports. Replacing a faulty board restores normal system control and smart-TV functions. What it does:

• Controls system boot, firmware, and menu/navigation functions
• Manages video and audio signal processing for the display and speakers
• Interfaces with HDMI/USB/IR/Wi-Fi modules and input ports
• Can resolve issues like no picture, no sound, frozen OS, or HDMI/input failures

• One main PCB board

• Disconnect power and allow capacitors to discharge before starting work
• Handle the board by its edges and avoid static discharge; use an ESD strap if available
• Reconnect all ribbon cables and connectors firmly and in the correct orientation

Fixes appliances that won't turn on or have intermittent power due to a frayed or damaged cord. Direct-fit replacement restores safe power delivery.
