My actions would be the following: try another display that is known to work, if it doesn't help, I would try to check the connection to an external monitor with and without a connected display

The trackpad contains a hall effect LID sensor. When the lid is considered to be OPEN, the display backlight is enabled.

Carefully check the voltage to ground of IPD_LID_OPEN_1V8.

Thanks for the update. I believe there is a lid angle sensor in the display that may have played a role in this fault.

I thought it was a problem with the display! Was it possible to restore Truton on the new display? They say you need to move the camera from the old display to get the Truton back!
