Hi, my friend has an iphone 6s that suddenly has black screen and it does’t recognize from any pc. I’ve tried to change several display but nothing, ever black screen. I’ve changed battery e charging port but still non recognized from any pc. If I connect a usb tester to the phone and it absorbs about 1mAh-1,4mAh. Thanks in advance.
Es esta una buena pregunta?

Try a hard reset, you can look up how to do it on YouTube. I would also check the tristar ic with a tristar tester. The tristar ic is the chip that controls the charging and its also the chip that allows data to go from the iPhone to and from the computer. It will work until the battery dies but it won't recharge it. Try putting in a new battery, if it works it's a 99 percent chance it's the tristar ic

Test the power lines with a multimeter to see if any are shorted
