Why won't my Nokia Lumia 925 turn on?

[Windows Central Question]

I was charing my phone, and when it reached 100% I took it off, it froze and eventully turned off. Ive tried soft and hard reset. Ive tried plugging it in to my laptop. Ive tried putting it on the charger and doing a reset. Ive tried the NSU software update. Nothing seems to work the screen just stays black, no vibration or anything. Please help!

You'd better take it to the service centre. Professionals will take care of and if something wrong happened , they will replace the device or repair it.

In your post you mentioned that the screen stays black then how were you able to do a hard reset??
