There is conflicting information regarding the main processor. While most product listings state it uses a Rockchip RTD2982, a technical teardown suggests it may use a TV-5602 SoC from SMIC, indicating possible hardware revisions.

The is one of the most widely used three-in-one LED TV driver motherboards in the electronics repair market. Manufactured by Top-Tech, this board integrates the main processor, a LED backlight driver circuit, and a power supply unit (PSU) onto a single substrate. It is commonly found in budget-friendly 24-inch to 42-inch LED TVs from various local and international brands. Tp.v56.pb801 Schematic Diagram Pdf
