Default Re: Lg 32lb5700 no power on led

You are missing a signal from the mainboard to turn the leds on. DRV_On should be approximately 3.5V
Disconnect the mainboard from the power supply and connect a 1K resistor from 3.5V to PWR_On and a second 1K resistor from 3.5V to DRV_ON
Willing to help but I'm no expert.
