How to Repair iPhone 7
If you’ve ever seen the iPhone’s screen after taking a photograph and you’re wondering how to repair iPhone 7, the answer is relatively simple. The problem lies in a tiny bit of plastic stuck inside the unit, which can only be seen with a good magnifying glass. Fortunately, this small bit of plastic is easily removed with the help of a small screwdriver, but if you don’t have access to such an item, you may also try to use your fingernail to get it out. Just make sure that you use a soft toothbrush to do so since any sharp object may damage the screen. It’s definitely not a very popular repair, but it’s by no means impossible to fix.
The first step you need to take when learning how to repair iPhone 7 is to disconnect the device from the charger. Then take the device apart, making sure that all the wires are disconnected. Once you’ve done that, you should try removing the circuit board from the back of the unit. It is located below the display panel, but should be accessible via the back cover. You should remove it carefully using small flat-tipped tools. The circuit board is connected to the motherboard through a copper ground wire.
After removing the circuit board, you can now take apart the battery. The easiest way to do this is by gently pulling at the battery, but make sure you don’t bend the battery as it’s possible to cut it. After cleaning the battery with some type of soft cloth, you can put it back in the charger. Now, all you need to do is attach the circuit board to the motherboard through the circuit board terminal. Finally, you can plug the circuit board back into the unit.
