Screen Reacts to Touch But Does Not Unlock Phone

Hi.

First-time inquirer…long-time reader. I’m a novice unpaid iPhone repair guy, having replaced 20-30 screens over the past several years. I’ve made bonehead moves, like not disconnecting power before replacing the LCD digitizer.

But this time, I believe I made a clean replacement of a screen for an iPhone 6s. After replacement, the new screen did not respond at all to touch. Since the old screen was functional, I returned all components to the original LCD, thinking I had a bad new screen.

After putting it back as before, the old screen will not respond fully to touch. By that I mean I can attempt to unlock the phone by pressing the key pad, but the privacy-protected digits would not light up. Not only that, but the code i KNOW is correct will NOT unlock the phone. When trying to power down, the slider will FINALLY power down after multiple tries…most of the time.

In other words, I can’t get into the phone. I’ve tried rebooting but nothing. I have NOT tried a hard reset since I do not know if all the data is backed up from this phone or not. Any other suggestion?

Thanks!

Maybe check the screen connector on the board? Could be bent pins / dirt in the connector needing cleaning with brush and isopropyl alcohol.

Thank you Ben. I did, in fact, check all the pins per your suggestion. All looked good. Turns out there was a conflict with the accessibility function on this particular phone. When I finally was able to turn off that function, the screen began to work again! The "new" screen was bad so I've ordered a new one.

This sounds a lot like “dog damage” MacBooks are like dogs, iPhones are like cats. When not working under a microscope, it is really easy to treat an iPhone like a dog instead of a cat. The result is micrometer differences in the positioning of the pins of the digitizer connector. It sounds like your *most likely* case is some mushy-mash damage to the pins of the connector as they sit in malleable plastic, combined with matching damage to the screen.


If the end user cares about their data, I’d get this phone to someone with a microscope to investigate the connector before trying to plug anything into it. It is REALLY easy to permanently kill the image on an iPhone 6s with a bad connector. I just wrote a blog about a couple of similar cases. There are pictures of what connector damage look like here: http://www.ipadrehab.com/article.cfm?Art...

Great post and suggestion, jessabethany. I did check all the pins on the motherboard and the ribbon connectors and all looked good. Turns out there was a conflict with the accessibility function on this particular phone. When I finally was able to turn off that function, the screen began to work again! The "new" screen was bad so I've ordered a new one.
