As the title states, I replaced the battery in an iPad Pro 9.7”, and now the iPad won’t turn on. No LCD display. I plugged the iPad into a laptop and it was recognized by iTunes. The installation went fine and without problems, and I’ve done it before, so I’m confused what the problem could be here. I’ve triple-checked all the connectors and everything that could be loose to prevent the LCD from powering up, and I can’t find anything. Any advice would be appreciated
was the battery connected when you connected the display? sometimes people can blow the backlight circuit when they connect the screen while the battery is connected. If you shine a flashlight on the display while attempting to wake it up or turn it on that’s a quick and easy way to diagnose a blown backlight. also what did iTunes say when you connected the device? Was it in recovery or DFU mode?
