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

Provide the voltages you measured at the secondary connector pins.

Inspect the small startup resistors near the pulse-width modulation (PWM) controller. 17ips72 schematic

before performing any continuity or resistance checks.

If the TV shows no signs of life, start at the primary side. Uses a dedicated controller and MOSFET to pulse

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

Inspect the optocouplers and TL431 shunt regulator responsible for voltage feedback. 💡 Sound but No Picture 17ips72 schematic

If the main fuse is intact but no standby voltage exists, the low-power standby IC might be defective. ⚡ Unstable or Pulsing Voltages
