hi,
when came to me, there was no backlight. BKOFF# was 0V, so DISPOFF# = 0V, i connected +3v to dispoff# now back light is ok, but another problem ; screen back color is green now. i replaced lcd screen with a new one, now its ok, back color is black. But this time, text is purple. :) any suggestions ?
thanks!


i changed with another new screen and the back color is green again. So i think original screen is also OK. Please some advice, why it is green ?

Check resistance on LVDS pairs to gnd.
There is a discrete GPU or CPU only?

There is a discrette GPU, NVidia N13p, switchable graphics. But LVDS_A0..A2 pins are connected to hub.

pin 13. A2 = 2m ohm
pin 14. A2# = 2m ohm
pin 15. A1 = 0,46 ohm
pin 16. A1# = 23k ohm
pin 17. A0 = 2m ohm
pin 18. A0# = 2m ohm

differ from other, isn't it?
and all LVDS pairs go to hub...

yes it is, so should i reflow the hub ? (hm76) i cant find a new one.

no reflow, need to change to a new one.
