iPhone 6 no backlight repair

Image
I found several articles about replacing actual coils and IC chips. I then found several sellers on the VIP Pro Shop team, offering about 15 to 30 replacement coils and IC chips. If you have the right equipment, they all claim that the repairs are reasonable and feasible.                                                                                                                                           A customer sent us an iPhone 6 to repair, the fault described is that the iPhone touch screen  is not displayed, but the screen is good and the iPhone motherboard can also work after the iPhone boot and the button is normal too. ...

We at the vip pro shop team provide you with a safe and speedy option for getting your water damaged iPhone 6 fixed. Our experience is what you need to get your device working again. The customer said that his iPhone cannot be turned on after dropping into water.He opened the front panel and cleaned it. There are some bumps on the upper cover of CPU. Repair Process Tear down the iPhone and connect the motherboard with adjustable power. Let it standby but there is no current. We can be sure that the main power supply is not short circuit. Triggering it on, the current changes to 50mA and then it is power fail, but goes back to 50mA again automatically. It repeats the former process again and again. If the output voltage from iPhone 6S power chip is short circuit, the chip will get into the protection mode. Therefore we measure the diode data to ground of CPU upper cover, finding no short circuit. Then we measure the diode data to ground of each power supply, as shown in pictur...

If your iPhone 6 WIFI can't work and the icon is gray during the normal using process,we've got the troubleshooting guide for you, this situation should be that the iPhone 6 WIFI module  has no work.How to provide the best solution for this kind of fault? Test whether the main power supply 4.2V has been delivered on C5202_RF, if not, it can be supplied from any place with main power supply, or directly replace WIFI module. Before disassembly, we need to do some protection to avoid blowing other chips. The WIFI module is surrounded by glue. We must first preheat and remove the glue, and pay attention to small components, especially small resistors. you must to solder it again if some of the components are lost. The WIFI module on line is relatively thin, do not use solder iron  back and forth on iPhone solder pad, testing resistance again after cleaning. As shown in figure 14-5-3, the lower right-hand corner is easy to break, and the normal is infinite. Therefo...
