Samsung Television QN65Q80AAFXZC Parts

This is the main PCB assembly for the TV — the primary circuit board that runs the set's control, video and audio processing so the TV can power up, display picture, and respond to inputs and the remote. What it does

• Hosts the TV's main processor and firmware that control menus, input switching, and overall system operation
• Processes video and audio signals to generate the on-screen picture and sound
• Manages HDMI/AV inputs and communication with other boards (power, T-con, tuner)
• Causes common symptoms when faulty: no picture, no sound, no menu/OS response, or unresponsive inputs/remote

• One (1) main PCB assembly as shown

• Unplug the TV and disconnect all power before attempting any repair
• Observe ESD precautions and handle the board by its edges to avoid damage
• Some disassembly of the TV back panel is required; keep track of screws and connectors

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.
