Yesterday, I replaced the battery in my phone and it worked just fine afterwards. But today, the screen has randomly stopped working. The phone still works fine since I can make/take calls, use siri, put in my passcode, but I just can’t see anything on the screen whilst I’m doing it and so I am guessing if I am pressing the right thing or not. The screen doesn’t stay off forever; it stopped working twice today and I just left it on the table and about 30mins to an hour later, it works. But after a bit of time it turns off again. I looked on Google and tried the hard reset of the phone. I also tried opening up the phone again and making sure that the screen connectors were put in place properly. These didn’t work. Will I need to give it to a repair shop?
You have electrical damage on your backlight circuit from connecting the display whilst the battery was connected. You can confirm this by connecting it to 3uTools and see if it displays your screen or shine a torch on the screen when booting and see if you can make out the apple logo. If not it is an image problem and wouldn’t be worth repairing. There are about 9 components on the backlight circuit that could have been damaged but if you are lucky it could just be one of the filters. You will not be able to repair this yourself unless you have the equipment and experience in microsoldering. The repair cost would be around $100 or more if the LCD connector needs replacing. It might be time for an upgrade.
Hi Edwin, How unfortunate. This sounds to me like a logic board problem. If it would be a problem with the screen or connectors, usually it will work all the time, or none of the time. Talking about the iPhone 6s I would not recommend bringing this to a repair shop. The shop I work at will only start doing logic board repairs from €80 and up. Meaning if you would repair it it would be close to the cost of an iPhone 6s. And repair the problem you have will not guarantee you that no other problems can occur after. I would suggest looking for another phone. Kind regards
EdwinG double check on the components on your logic board. Make sure that none came loose or even off. Check the connectors carefully for any burned pins etc. If all that is okay I’d try a new display assembly since they are still affordable.
