My macbook had a broken screen and I disassembled it and the T-CON board. I use the below with an external monitor. How to force turn on keyboard light without monitor and T-CON board?
Sadly this is just not possible! No different trying to drive a car down the road without its rims. Apple’s design now prevents any options like we could do with the older 2015 and older systems using jumper. You need to replace the display assembly and any other damaged parts.
