Wont turn on with Trackpad connected.
Disconnecting the trackpad it will turn on fully with LCD working.

LT400 was burned.
Reconstructed it and replaced the Coil.
Now it turns on but no backlight.

Do you still get backlight without trackpad connected?

 

[Instafixx]

Yes

Check IPD_LID_OPEN_1V8 signal w/ and w/o trackpad connected.
It should be always high.

Issue was solved but i know i am getting Sleep/wake issues and trackpad and KB not working.
AMR_RIGHT_OR_ND_1V8 was 1.3V
Replaced RR300 to force the signal to 1.8V

Sensor working fine. But no KB/TP
IPD_LID_OPEN_1V8 is always high.
