17ips72 Schematic Work -

Upon receiving AC, the board first generates a low-power standby voltage to run the TV's infrared receiver and main processor.

The 17IPS72 is a Switched-Mode Power Supply (SMPS) designed to convert high-voltage AC mains into stable DC rails for the TV's internal components. Key sections of the schematic include: Upon receiving AC, the board first generates a

The circuit starts with an input stage featuring fuses, EMI filters (LF1, LF2), and a bridge rectifier (D1) to convert AC to raw DC. Most 17IPS72 variants include a PFC stage to

Most 17IPS72 variants include a PFC stage to improve efficiency. This involves a PFC Controller IC , a large PFC MOSFET (typically on a heatsink like HS1), and a boost inductor to maintain a steady +400V rail.
