Converts the transformer output back to low DC voltages.

Once you provide these details, I can offer a step-by-step diagnostic plan mapped to the board layout. YouTube·MrReeceyburger123 17IPS72 Repair 17ips72 schematic

A typical switched-mode power supply (SMPS) board like the 17IPS72 features several primary circuits. Converts the transformer output back to low DC voltages

If the TV turns on and yields sound but shows a blank screen, the LED driver is often at fault. The 17IPS72 schematic includes an LED step-up converter. Test the output voltage at the backlight connector. If the TV turns on and yields sound

Provide the voltages you measured at the secondary connector pins.

Test the filter capacitors on the secondary side. Vestel boards are known for using capacitors pushed to their exact voltage limits, leading to premature bulging and failure.

Uses a dedicated controller and MOSFET to pulse high frequency DC into the transformer.
