hi is it possible to replace topcase from A2337 M1 chip without problems? or is it possible that the mainboard dont turn on after that until apple service turn off the blocking?

ok, so that means before i reballed u3900 the chip was with problems as well?

with el capitan is the same effect. only that it drops to zero later, about this moment when the screen is flicker before curser can see. (in osx elcapitan half way from the load line under the apple logo)

PP1V2_CAM_XTALPCIEVDD has 1.19V and it drops to 0 like the 25Mhz Signal in about 1/3 of the line under the apple logo while loading osxi now will try osx el capitan
