Hardware repair samsung galaxy s6 edge+ black screen
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
1. အရင္ဆံုး သံဖုနး္ကိုခြာပါ၊.
2. Measure the diode value on Pin 3 and Pin 4 ကို တိုင္းပါ၊
3. Continue to measure the diode value on Pin 25 and Pin 27. Judging by the measured value, circuit from OLED connector to F9013 is in normal status.
4. So the fault may be related to F9013. and we need to replace with a new F9013.
5. Align to the right place and solder with a new F9013.
5. Align to the right place and solder with a new F9013.
ကိုျပန္တတ္ေပးလိုက္ပါ၊
Assemble the phone and test. Press power button to power on. The phone turns on with normal display and normal touch function. Fault cleared.
