The is a standalone switch-mode power supply (SMPS) board. Unlike integrated power/main boards (combo boards), the 17IPS12 is a dedicated PSU that provides all necessary voltage rails to the mainboard, backlight inverter (or LED driver), and audio amplifier.
Secondary side filtering capacitors (small electrolytic capacitors) for high ESR. Check: Output diodes (STPS20H100CFP) for shorts. 4. Where to Find the 17IPS12 Schematic vestel 17ips12 schematic
Search these exact strings. Also, search for the "service manual" of a TV model that uses this board (e.g., Toshiba 22DV713B or Hitachi 22LD315DB). The is a standalone switch-mode power supply (SMPS) board
