@danj Thanks Man,

I’ve soldered pin right to its place but, screen still does not have backlight .

I’ve check continuity on pins and they looks ok, two pins on left have same connection to the chip below is this correct ?

I want to make sure that Logic board is fine before ordering a new screen :)

@danj thans for the tip :)

does anyone have information about voltages i should see on this pins ?

Sorry I don't have the schematics for this series. I would just test continuity across the connector pin by pin.

Be very careful! Push the pin back through the plastic go slow and make sure you don’t over stress things!

Once the pin is at the same elevation as the other pins, carefully solder the pin back down, hopefully the pad is still present.

Before you push the cable back on make sure the pin is inline with the others.
