Hey all this one came water damage. lvds was bad and ppvout_sw_lcdbklt pins were gone. SO i ran jumpers and turned on the macbook and boom - instant smoke.
So i go over thunderbolt and check all components around u9410 and make sure everything is good. Re done the u9410 now v2 with jumpers to get connection as it burnt out prety bad and again - boom and it smoked.

Can anyone help?
thanks

Forget it remove U9410 and live without thunderbolt it is a total waste of time. Does the board have backlight and turn on without U9410?

Are you sure is short there???
Is impossible, if board starts...
I hope you removed charger and battery when checked that.

"pin 2,3 no voltage but 4 is measuring 3.33v"
Do you talk about J9000?
Check volyage and resistance to ground at pins 6 & 7.
