Chosen Solution
After successfully replacing broken iPhone 4 and 4s screens and replacing batteries on 4, 4s and 5 without problems, I thought I was getting reasonably skilled at such tinkering. So you may imagine my disappointment after powering up a 5s after I replaced the broken screen (for the second time!) and saw that the screen’s all wonky.
Before I climb back under the hood and start fiddling with connections, I’d appreciate feedback from more experienced tinkerers. Do you think it’s a bad connection or is it LED issue?
Lines often show up when the connectors are dirty of broken. Disconnect and inspect the clips carefully. Make sure there is no dirt or corrosion and that all the clips are present on both side of the connector. Clean them with Isopropal alcohol .
Hi there, This is either a loose connection or damage to the LCD flex cables. Open the phone and see if they are seated correctly. Another thing you can do is with the screen connected, wiggle the screen around to see if its the flex cables around. You may need to purchase a new screen entirely. Good Luck
Is the video (uppermost) plug. I replaced my wife’s screen this weekend, same result like you. Reseating the plug ( multiple tries) finally worked. Just make sure you unplug the battery while “having fun”. The phone is allergic to hot plugging.
There are two problems. 1) The flex who conect lcd with board maybe is broken in moment when u close lcd. 2) This maybe will be a problem with lcs filters and this is a big problem, only a specialised service can solve this. My sugestion is to reasembly LCD and see if peoblem persist or try with another one lcd.
