Purchase faulty iPhone xs. Screen does not show anything.

Hello friends,

I am yet again to buy a broken iPhone. I've fixed iPhones before, but not an xs. But I'm certain I can fix it, just a question about the cost of it..

It's an auction.

Faults

• Smashed rear glass
• Nothing shows on screen.

Replace screen and rear glass wouldn't be a problem.

The phone react to iTunes and charging.

So my question really is - Do you guys have any ideas of why it doesn't show anything?

Could it just easily be a screen replacement?

Thank you for your inputs.

And as always —

~May the patience be with you~
