Phone won't turn on

My Iphone 6 turned off at once. It is not water damage or something else. Then i put into charger and phone heat up. Then i put it into pc(iTunes), and iTunes doesn't recognied it. I pressed home button and power button for 30 secound then pc recognized it but iTunes isn't. Then i was dissconected battery flat and put it back, press down home button and put usb into pc. I put phone in recovery mode, then restore phone and now iTunes recognised it. All the time my screen didn't turn on. I put SIM card into my Iphone, call my number from another phone, My Iphone don't ring and i can't decline call when i press power button. iTunes and iTools recognized my phone as if everything is fine. I thought that my home button is not working, but when i press home button + power button, phone will turned off(i can hear when it is dissconnected from pc). What's the problem?

I'm going to do my best to diagnose this step by step.

Your phone stopped working all of the sudden, without water damage. That's usually the sign of a failure of some part of the motherboard.

iTunes didn't recognize it but your PC did. That is another sign of motherboard problem.

After a flash, iTunes does see it. OK, that's good. That means that the iPhone is somewhat working.

Phone doesn't make or receive calls, screen doesn't work.

That's going to be the symptom you focus on. My first instinct is to try a new screen. I can only think of 2 things that would cause your issue: a drop that damaged something or knocked something loose or a corrupt memory. The latter isn't really common, so I'd lean towards the former. So if its drop damage, that's pretty easy to inspect. The first thing is to try a new screen. If that works, great. If not, then you will need to inspect the board for loose or damaged ICs. iFixit has a great youtube video showing how to do that.

To sum it all up: It sounds like you either have a bad display or some board level issues. The bad display would be the easiest fix, so try that first and then update us.
