Screen issue (blank)

What you're paying for

A display that stays black while the phone is clearly running. Worth ruling out a flat battery first: if the phone doesn't vibrate, ring or respond to a charger at all, the power fault is priced lower than the screen.

It is the 9th cheapest of the 18 repairs Google prices for this phone here. That's 1.5× the cheapest repair on the list, and it sits below liquid damage at €468.63.
