: Check the voltage at the LED output connector block. If the voltage spikes up briefly when turning on the TV and then drops back down, an LED strip inside the panel is open-circuit. If the voltage never rises above the basic supply rail, focus on the LED driver boost MOSFET or its controller IC on the board. Where to Download the 17IPS72 Schematic
