Chosen Solution

So I drop my iphone and my display stoped showing any image (it went all black but it had light) so I figure out that maybe a connector from de display got disconnected in the fall. I opened my phone to see if something got disconnected but when I disconnected the battery I think I may or may not have induced a short circuit in the battery terminal (I disconnected it with a screwdriver so the positive and negative made contact). The battery inmediatly got discharged, but I let it charging for a while and now is back to normal, but the Iphone just won’t turn on at all. Someone told me that it was because when a short circuit happens in an iphone sometimes it blocks and you have to change an integrated circuit in the mother board. Is it true? Or is there another way I can fix it? PLASE HELP ME :( Ps: Sorry for my English haha it’s not my first language

Try squeezing home button and power button at the same time. Take into Apple Store. Friend had same problem and she took it there they fixed for free. Don’t try and fix on own. You could be further messing up the phone. P.S I understand language problems. English isn’t my first language either. Struggle is real
