Hey sir,

I have motherboard nm-d471 rev. 2.0.
Problem is with lcd backlight. When i turn on laptop picture shows up but without backlight. Fuses are okey, sot 23 near to lvds con is replaced for new, lvds conector have all contacts okey. Tried new lvds cable + new display, same issue no backlight. Can it be bios issue? It is last chance i guess than i can say good bye to chipset right?

Thanks for help!
