Got mbp 15 A1707 touchbar with water damage. There was damage near lcd area and short on U7220. Changed it and now machine seems to start ( 20V 1,5-2,5Amps). No shit on lcd connector and FPC:
I checked and see that EDP_BKLT_EN is 0V so it's not enabling backlight , right?
This signal is generated by U9800 checked and it's not generating 0V on R9827.
The problem is that it doesnt start even with external monitor. I dont know what this machines do when you connect external monitor and boot them.
Also it's strange that CPU is getting just warm and GPU stays cold.
Any idea?
