iPhone won't charge but logic board gets warm
Okay so I was recently changing an iPhone 7 screen and I unplugged the battery from the logic board. I know it’s stupid but I didn’t realise the screen was still turned on. Now when I charge the device it no longer turns on or shows any response. However, after a while the logic board gets warm. I’m not an expert so I need a little help. It’s definitely not the screen because it was working before. The backlight is fine and the charger is working. Any ideas as to what the problem might be?
