Chosen Solution
I recently got my phone fixed a couple of days ago and randomly the screen turned black. I did not drop the phone. It isn’t water damaged. I searched it up online and there was a forum that instructed me to plug it in to my PC, open up iTunes, and I did as told but my iPhone 6 is still unresponsive. I tried pressing the home and power button at he same time and that didn’t work. The lcd isn’t broken
Ben should be right. it sounds like either the display was damaged or is not correctly plugged in. I would take it back to the shop as soon as you can for them to have a look.
I’d suggest asking for your money back and going to another shop. Sounds like they just don’t want to fess up to their mistake. Good luck.
I’ve had a similar problem with the iPhone 6, it turned out to be a defective screen, i used the screen for about 20 mins and it turned black, contacted the supplier and he offered a replacement, they seem to be copy screens not originals that have this issue
