If your replacement lcd-digitizer assembly was refurbished, the digitizer could have been stressed to make it failure prone. LCD’s are easily damaged, depending on the refurb and bonding process. Liquid (LOCA) glue residue found near/on flex cables is often a hint. Also, another good possibility involves the flex cable connectors themselves. Did the replacement LCD-digitizer cables have foam pads on the back side of the connectors or just shiny metal? If those foam pads aren’t there, when you go to place the connector’s cover with the 3 screws, any one of cables have room to pop off when positioning the display. When you press down on the display, it may be enough to flex the display and temporarily or partially make a connection at the cable ends (upper right corner of screen) underneath and/or nudge a defect (crack) present in the digitizer panel, which is just below the glass surface.
Hey, there, I am having the same problem with my iphone 5s as you described. I dropped the phone on a tile with its cover, and it is not responding to anything. I can only turn it on or off using the home&lock button. Should I follow what you have done on your phone? I’m so embarrassed now, but somewhat relieved to know that this sometimes happens.
Hi Friends! My Mother just dropped her 5s (a1457) and now the touchscreen is unresponsive. I am following the Guide from Apple about restoring the Phone via iTunes since the Home and other buttons do work … But I noticed that there is some kind of purple hue on the otherwise white Background. I took a photo of it and hope somebody can tell me if this is something known …
Well anyhow - the upgrade via iTunes didn’t help. No suprise there but - before I give my 6s to Mama I wanted to try this. I guess repairing an 5s is not a good idea. Cheers mates! :)
