Power Supply Board TV7001-ZC02-01 Fit for ONN E021M425-J1 E021M509-B2 for Haier E021M425-J3 E021M509-A2

Specifically engineered for 70-inch TVs, this power board is perfectly compatible with models E021M425-J3, E021M509-B2, and E021M509-A2, as well as associated models like TV7001-ZC02-0ar. The interface pins and mounting holes are identical to the original factory part. As the central power supply component for the TV, it reliably converts 220V mains power into the multiple voltage sets (such as 12V and 24V) needed by the TV motherboard, screen backlight, and audio module. The output voltage error is 1.5%, ensuring a steady power supply for optimal picture performance. It utilizes a thickened FR-4 PCB board with high heat resistance, able to endure operating temperatures up to 60, making it appropriate for the thermal conditions from extended TV use. It features five protective mechanisms including overvoltage, overcurrent, overtemperature, short circuit, and lightning surge protection. Should the input voltage become irregular, the load be excessive, or the board's temperature surpass the limit, it will automatically shut off power to avoid harm to the TV screen, motherboard, and other valuable parts. Before purchase, please verify the product model. It is advisable to compare it with your old component to confirm it is an exact match
