Turning off backlight | bypassing the protection: on the inverter board there is no resistor in the R8159 position from the factory, many say to put a 10k resistor in its place, but the brightness of the LEDs is very low. I put a 20k resistor and it was perfect, great brightness and the backlight no longer turns off | ZW ELETRONICA | |
