Hi All,
I am trying to diagnose a EAX64905001 power board. The back-light will not come on. I have tested the LEDs and they are fine.
From reading another post - if I short 3.5V and PWR_ON with a 1k resistor - these are voltages I get.
PIN --- OUTPUT
3.5V = 3.47v
24V = 24.7v
12V= 11.94v
If I need to test the LED+ and LED-. Do I need to short DRV_ON with 3.5V? (I'm guessing this stands for LED DRIVER.)
Many Thanks, J
