Customer says his Samsung galaxy s6 edge+ turns on with black screen, the LED indicator was pulsing and the buttons were lightening. Since the black screen and graphics issues are resulted from OLED circuit related problems. measure the voltage value on C9028 and c9026. Normal value.
measure the diode value of each pin on OLED connector. no value on pin 25 and pin 27.
so the fault may be located to F9013.
detach F9013, and the diode value on pin 3 and pin 4 of F9013 is normal this time. next, replace with a new component and test. fault cleared.
This is the detailed repair guide here.
