iPhone 6 Plus right Screw hole is disconnected, so no display can’t be turned on for maintenance
Machine model: iPhone 6 Plus
Fault description: no display can’t be turned on.
Maintenance process: First of all, after power-on observation, it is found that the current is 20-40-80ma cyclic tripping current, which is usually caused by problems with CPU or I2C bus. After removing the motherboard, it is found that the right Screw hole has been replaced by Scraped.

It seems that this is the problem here, because this Screw hole takes the 12c bus, so scratch it off and restart Jump wire.

After the repair, the machine turned on normally, and the test function found that there was no earpiece and front camera.

Because Front Camera and earpiece are Front Camera FPC, I will try another FPC first, and the Front Camera and earpiece will be used normally.

Here, the maintenance is over.
