Hi, I’ve replaced my iPhone 7 Plus screen, when I’ve connected everything and powered up there is no response from the Home button and the wi-fi symbol is grey and crossed out. I’ve tried to re-seat the connectors a number of timesI’ve bought a secondary replacement but that does the sameI’ve connected up the original broken screen and both the wi-fi and home button are fully operational again. Has anyone experienced this before?
Okay so you have two problems. 1. Home button. If the home button works with the original screen it means the screen replacements you are using are faulty. 2. Wi-Fi is greyed out when using replacement screen. This could be a problem as the main reason Wi-Fi gets greyed out is a power issue going into the IC. A screen should have no influence on this, if it did the phone would not boot. Try your original screen without installing it in the housing and check Wi-Fi. Do the same with one of your replacement screens. I think you will find they both have the same result whichever it is. If they show the same result it would confirm Wi-Fi IC issue. Most likely from the screens being different, resulting in a variation of pressure being applied to the Wi-Fi IC from the screen when clicked into the housing.
