Why does my screen go black randomly?

I recently replaced my broken screen on my iPhone XS Max with an IFixIt LCD screen. Since my phone screen was completely unresponsive to touch before replacing it, i wasn’t able to shut my phone down before repairing the screen. I just unplugged the battery connector and went on with the procedure. Now, randomly, my phone screen will go black while i’m using it but the phone is still on. All it takes to fix it temporarily is to turn the phone off and on. Now, is it because I unplugged the battery connector during the repair without shutting the phone down or is it a faulty screen? Please Help!!!!!

Unplugging the battery connector would not have caused any damage. In your description you say it is an LCD screen and these can be problematic and you should have purchased an OLED screen. If it is an OLED screen I would back the phone up and do an update or restore and see if the problem persists, if it does you will need to return the screen for a replacement. Before you do though I would make sure the top flex connector on the screen is seated properly and if the screen is losing image or backlight, you can do this by shinning a torch on the screen and see if you can make out an image.

Hi @imicrosoldering

I thought OLED screens didn't have a backlight as the light comes from the pixels themselves, but I'm always willing to be corrected if I'm wrong ;-)

Cheers

@jayeff You are right Jeff. I was thinking if the ambient light sensor was playing up you should be able to see an image with a torch shined onto the screen.

WAIT...unplugged the battery connector during the repair without shutting the phone down?!?!?!?

congrats< now you need to replace the battery because you messed up there.

and also did you transfer the data of the original iPhone screen? that could be a problem 2
