I replaced the LCD in my iphone 6. Upon reassembling and trying to power it back on nothing was happening. I plugged it into the charger and after a minute or so it started making the charge sound every few seconds meanwhile the screen was still completely blank. I then plugged it into my computer and itunes recognized it completely along with all the stuff i had stored on it. The screen is connected 100% correctly. Im completely baffled. Any and all inquiries are appreciated.
This has happened to me several times upon installing a new screen for a client’s phone, but simply unpluggin and discharging the battery, then plugging in again resolved the issue. As for someone whose LCD started fading to black one day - that is a mystery to me. It could be that the connectors have lost their capacity to flow electricity through them to the LCD, and thus no new screen will work.
