the inverter does not work, and when ENB=3V, the inverter is in a normal working state. The DIM voltage is provided by the mainboard, and its variation range is between 0 and 5V, and different DIM values are fed back to the feedback terminal of the PWM controller. The current provided...
If that doesn’t work, you may need to replace the backlight inverter board or the power supply board. You can do this yourself if you’re handy with a soldering iron, or you can contact LG customer support for assistance. What to Do If the Automatic Dimming Still Isn’t Fixed? If ...
