Fix iPad Pro Not Turning On By Replacing Connectors

Blake Jun 25, 2021

We have received an iPad Pro from our fan. The original fault of the iPad Pro was the top left corner speaker with noise. After speaker replacement, the connectors of the motherboard and display are burnt out while connecting the display. Now the iPad Pro won’t turn on. So the fan mailed the iPad Pro to REWA for repair. Let’s check out how we fix the iPad Pro.

In the first place, we remove the display. We can see that the connectors are burnt out. Since the battery is connected to the motherboard, the connectors will burn out with the device turned on and display connected. To avoid unnecessary damage, we recommend you disconnect the battery first during repair. After the display is connected, connect the battery to turn on the device.
