iPhone 7 backlights not working 24hrs after screen repair
Hi, I had done a screen replacement for an iPhone 7. Everything went very smooth and device screen turned on with no issues. Was able to reboot multiple times. Customer tested before leaving and was working great. Now, customer came back today, less then 24hrs with the backlight out. I can see the LCD if I hold it at the right angle. Any ideas on what may have happened to cause this?
