Required Tools:
- Screwdriver set (Phillips, Torx)
- Plastic prying tools (spudgers)

Installation Steps:
- Prepare the Work Area: Ensure a clean, well-lit, and spacious work surface. Place a soft cloth or mat to protect the TV screen.
- Disconnect Power: Unplug the TV from the wall outlet and disconnect all external cables.
- Disassemble the TV: Carefully remove the TV's back cover, stand, and any internal components (e.g., main board, power supply board, speakers) that obstruct access to the display panel. Document screw locations and cable connections.
- Remove the Display Panel: This is the most delicate step. Carefully detach the display panel from the TV frame. It is highly recommended to have a second person assist with this to prevent damage. Place the panel face down on a clean, soft surface.
