The following lists the problems that iPhone 4 often encounters during iPhone 4 Maintenance:
1. Changing the screen iPhone screen for tempered glass is relatively brittle, please be careful when your ip4 drops to the ground, especially in winter
IPhone 4 LCD touch is integrated and inseparable. If there is any small damage, you must change the full screen.
2. There is no sound fault when I call the iPhone 4 for repair. Most of the problems are caused by the failure. The fault is: when I do not call, all sounds are normal, and when I call, all sounds are lost. Cause: the audio chip on the iPhone 4 motherboard is damaged. This chip provides sound channels for telephone sound, and is made of glass, therefore, if the phone call is not audible due to a crash, 100 is the chip.
3. Repair iPhone water dispenser. The iPhone battery is a built-in battery. If the battery enters the water, the battery cannot be removed, and the motherboard will always be powered. It is easy to burn out the motherboard components. Never be lucky to use them in the sun or in a hair dryer, that's wrong. Because the main board is always powered, it is possible that a part of the water may have been soaked in the drying method, and the water is blown to another place or the temperature is too high, the water becomes water vapor, there will be water in all the phones. Solution: if you are a customer with strong hands-on ability, you can promptly split the back cover and remove the battery. Drying should be okay. If there is no tool but it cannot be split, we should hurry to find repair. If so, we should just clean it up. Possible faults: three faults (no serial number, signal, WiFi), no boot, automatic shutdown, no computer connection, no wifi, no sound, and other faults.

Cause: LCD lights are powered in series, and the motherboard supplies 18 V for screen lights, which is the highest voltage on the motherboard, if the motherboard is slightly wet, the working environment humidity is high, or there is static electricity, it may cause the screen lamp boost chip to burn out, resulting in the screen lamp is not on. Solution: Change the screen lamp to boost the chip
5. Why iPhone 4 is not started: water enters, water falls, and static electricity. Resolution: The fault caused by water inflow is generally caused by a small amount of water, the host is not aware of it, from the End Plug (charging port) into the water, resulting in a greater probability of no boot. A broken mobile phone may have been used quite well at the time. After a few days, it will not start up. This is a manifestation of sequelae ,,. Static electricity is the most common cause of non-boot. The iPhone motherboard comes with a short-circuit protection function. If there is static electricity, the iPhone will automatically shut down. You need to plug in the power source or press the power key home together for 15 seconds to start up. In the first two cases, if the power plug-in cannot be started, it can only be sent for repair detection.
6. iPhone 4 often prompts (not ipone special accessories) or (with audio interference, You need to enable the flight mode) that is generally caused by water inflow. Some of them can be removed and cleaned up. Some of them are motherboard problems and need to be repaired.
7. The iPhone 4 handset sometimes does not exist. Fault description: it is better to press the receiver when the receiver is not available. Sometimes the sound is intermittent and sometimes the noise is high. This problem is generally caused by a crash or accidental pressure, resulting in a small deformation of the mobile phone, and the motherboard chip caused by welding or chip cracks, the need to re-build the audio chip.
