Samsung Television QN65Q72AAFXZC Parts

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.

This main PCB assembly controls the TV's core functions, handling video processing, audio, input switching, and on-screen menus to restore normal operation when the original main board fails. What it does:

• Processes incoming video and audio signals and sends them to the display and speakers
• Manages input selection, HDMI/AV ports and on-screen menu functions
• Handles power-on logic and communication with other control boards
• Can resolve symptoms like no picture, no sound, frozen menus, or unresponsive inputs

• Disconnect power and any external cables before starting work
• Use ESD precautions and handle the board by its edges
• Some disassembly (back cover, board mounting screws, connector removal) is required
