回答先: Not powering on after back glass breaks.Any time a phone is dropped, there is always the chance that something on the logic board can be damaged. It’s probably just coincidence at this point. But first, you’ll want to open them up to see if there are any connectors that got dislodged or if there is any visible signs of impact damage. Beyond that, I would suspect a logic board issue.
回答先: Home button loose bracketYou definitely want to replace the “black dot”, you can usually get them from another, dead, home button. That is why the click isn’t working when everything is mounted. As for the bracket, I find that using just double-sided tape makes for a squishy feel in the best case and outright slippery in the worst. I would start by properly cleaning all of the old adhesive aways, on both the screen and the bracket. Then apply good quality tape (3M/Tesa). Once the alignment is good and the button works properly, I apply a small bead of epoxy around the bracket (not on or near the flex!) - this is what Apple has been doing of late. This locks in the bracket and should make for a nice repair.
回答先: Screen Turn off after 1 SecondIt’s very important to always disconnect the battery before disconnecting/reconnecting the screen assembly. The issue is that the LCD connector has pins that have high voltages (i.e. the backlight is ~20V) and ground in very close proximity. When you fumble around trying to line up the connector plug to the receptacle, you can short out the voltage rail and cause damage to the components in the backlight circuit. If you’re lucky, then only a backlight filter is damaged but other times, the entire circuit could be affected. Either way, this type of repair requires micro-soldering and isn’t really a DIY repair. To test for this, plug your device into a charger or an iTunes enabled computer. Then shine a bright flashlight on the screen. If you can see a dim image, then the backlight circuit has been damaged. If you can’t see an image at all, then it may be the LCD circuit that is damaged. You can connect the original, cracked screen to confirm this. If the original screen has the backlight on, then the replaceme...
回答先: iPhone 8 Plus gyro/accelerometer malfunctioningDoes the phone look like it was water damaged in the past? The reason I ask is that when a logic board is contaminated with water, a common approach is to put the board in an ultrasonic cleaner to get rid of all the corrosion. However, the ultrasonic cleaner tends to damage the motion sensors (gyro, accelerometer etc) and that will impact the compass app and the ability to auto-rotate. That’s why most shops will only do data recovery on water damaged devices. So I would take a closer look at the logic board and look for signs of water damage (even if it is cleaned up, it will show to experienced eyes). You can always have this looked at by an experienced micro-solderer as well before investing too much money in a water damaged device.
回答先: iPhone 7 Logic Board OverheatingThere are some thermistors (heat sensors) on the logic board in various areas to automatically disable the phone if excess heat is detected. Normally you will see a thermometer icon on the screen if this is the case. If your phone is indeed overheating, that points to a hardware issue and is most likely a bad modular component which is causing excess current draw and hence, heat. You will need to either troubleshoot this yourself of have it looked at by an experienced third party technician as Apple won’t touch this. I would open up the device and disconnect the rear camera (battery first!) and then test the phone to see if it still overheats. If it still does, then progressively remove other components such as the front camera and buttons until the problem goes away. If none of that helps, then the issue could be logic bard related which would require a micro-soldering repair instead.
回答先: iPhone 7 Power button not working, all other buttons work fine.This is the circuit for the power button. Normally, when you press the physical button, it shorts this input to ground. You can see where it goes to the connector in this snippet. You’ll want to verify is those components are still present on the logic board, or see if the connector is damaged. You can also try shorting the BUTTON_POWER_KEY line to ground with some sharp tweezers as that would simulate a button push.
回答先: Charging port is broken? How easy to fix and would it still be insuredReplacing a charging port is a pretty standard (and easy) repair. You can check out this guide to see for yourself.
回答先: Is this backlight issue repairable? (not a board issue)There can be several causes for this “Stage Light” issue. It could be damaged, or partially damaged backlight filters or diodes. It can also be caused by excess heat when removing the screen assembly. Lastly, it could be a defective light strip in the LCD (that’s what this one looks like). In the last case, you would have to open up the LCD unit and replace the backlight directly, like a screen refurbisher does with an iPhone screen. I’ve never done this so I can only point you in that general direction.
回答先: Why wouldn’t my home button work after replacing the screenThe iPhone 7/8 series have a very inconvenient bend on the Home Button flex. It’s really easy to tear the flex, either near the logic board connector or at the 90 degree bend before it sneaks underneath the LCD heat shield. You have to be careful when you lift the screen off the first time but also anytime the flexes are connected and you have the device open. The other area that is easily damaged is the connector on the Home Button itself and the opposite connector on the short flex that runs underneath the heat shield. The long and short of it is that there are multiple failure points. You will need to carefully inspect the Home Button and flex to see if there is any damage. Even the tiniest tear can cause issues…magnification here will help. Look for tears to the flex or any physical signs of damage. You should also check the connector to insure none of the pins are damage or that there isn’t any debris. Unfortunately, there is no real DIY way to fix a Home Button, only Apple can replace it.
回答先: Can iPhone 6S models be susceptible to iPhone6/6+ "Touch disease"?The iPhone 6S and up does not suffer from “Touch Disease” per se. They can have touch related issues, which are almost always screen related, but not for the same reasons as the infamous Touch Disease on the iPhone 6/6 Plus. You can check out my blog post (linked above) for the technical details but in short, the IC’s that handle the touch functions suffer from some flaky copper traces on the logic board. These traces are very thin and will break over time as the iPhone is flexed through normal use (the iPhone 6 Plus is particularly “flexy” and it has a critical trace right where the board flexes the most). This can’t happen on the iPhone 6S (and up) because on those devices, the Touch related IC’s are embedded into the screen. The only thing related to touch on the iPhone 6S logic board is the circuitry that powers the touch IC’s in the screen. So it is possible that your specific problem is not screen related but not for the same reasons as the 6 Plus. In your case, if a known-good or high quality replaceme...
