iPhone won't charge or turn on after screen replacement?

Wow, I didn't even think that was possible, but your description was spot on. the cable was covering one of the screw holes. Once i re arranged the cables correctly, it started up without an issue. (except for the white lines on the top caused by a bad connector on the logic board). Thanks for posting your solution, it saved me from going nuts.

@dfransella, the white flashing bars at the top of the screen are due to a failure in the touch circuit on the board, usually requiring replacing the two touch IC. Be sure to have a back-up because once touch function is lost, you won't be able to back-up until the touch ICs have been replaced by someone competent enough not to cause secondary issues. Check my profile, there is a link to a list of micro soldering (mail-in or walk-in) technicians (all over the world) that can perform this kind of repair.

@rany , do you mind if I contact you? Just some general questions on going the microsoldering route. I have a few phones laying around here and stumbled on another today that are still dead after a screen replacement. Im not asking for help, just general advice on what route to take when I get these in.

Sure. Shoot.

I just replaced my wifes lcd screen on iphone 6. I was having the same problem. the phone would not turn on. looked online and found someone said to do a hard reset of the phone. so I held both home button and the top or side button for 30 SECONDS. you have to hold it until It show the connect to iTunes screen. after that it works great. I was going nuts connecting and disconnecting the plugs thinking I screwed something up during replacement. maybe people having this problem could try this and see.

thank you, that was my problem

Justin, i have this issue with an iPhone 5S, i got it to repair it, and on opening the device some of the screws and for example the heat shield plate on the CPU is missing, the cover plate on top keeping the screen's connectors in place also missing, when connecting the usb, i tested the port where the battery plugs in, i get 4.8V, this means there's power coming through, but i get NO reaction from the phone at all. what or where can i check to solve this issue?

I replaced the screen on my phone and now it won't turn on. I tried plugging it in and it made the charging sound. I Waited For A Few Minutes Then Hit The POWERbutton. It just made the charging sound again. And every time I hit the powerbutton. It makes the charging sound but still no response from the phone or screen besides that. Any help please.

If I took a simple guess I'd say the ribbon cable that controls the backlight of the replacement screen's LCD is disconnected underneath the screwed down metal guard. It comes up if you don't bend and tuck cables correctly.

we need pictures, this tells us nothing!!!!

That would probably solve so many of the comments above! Pic's are the best teaching aides. But for now I'm going to youtube the other best teaching aide,

My problem started when I replaced the home button cable that I throw cause my screen had issues it would open app's type on its own send text messages opening screen I 6 plus I didnt . Take battery lose phone worked fine each time but the last time I unplugged battery then it never turned back on . Sorry long post hoping I can help before I send back to warranty people. . I'll be back if I find a fix.

Hey, have you tried a Hard reset? (home button and on off button togheter up to a minuten un till you see the logo if it comes. IF you put the screws wrong you can damage some functions in the phone.

iPhones do not have removable SD cards that you can transfer to another phone/computer to extract the pictures. The data is stored on a chip called NAND that you can’t transfer unless you move over the CPU as well to a working board & that undertaking is very expensive with very low success rate.

The practical way to get your pictures back is to fix the phone. If your pictures are really important, I suggest you take it/mail it to someone specialized in data recovery from iOS devices. And reputable, because often you get just 1 chance to fix it & a failed attempt may waste that chance. I’ve lost count of how many times we could’ve saved the data & even possibly gotten a working device back hadn’t it been mishandled before it got to us.

As for what caused it, you may have put the wrong screws in the wrong holes & caused long screw damage. Or shorted something by working with the battery still connected, etc. Most of this is usually repairable. Good luck but stop trying yourself! It’s beyond DIY now.

You definitely smoked it by putting the screws in wrong. They arent all the same length, and I bet the longer one punched into a trace when you put it in the wrong location.

I didnt read all info the other posters wrote but if you had ICLOUD setup to backup pic's you might be able to recover most of the info so hopefully you have cloud program on your computer ????
