"iPhone 6s plus display vertical lines"に関する回答That looks like a bad display but you won’t know for certain until you have the phone and a quality screen replacement in hand. Always disconnect the battery first and re-connect it last! iPhone 6s Plus スクリーンの交換
"My phone turns off after 3 minutes"に関する回答I would try to re-install the original charge port to see if the problem persists. If it does, then you may have accidentally damaged something on the logic board (connectors) or one of the flexes. If the problem is not present with the original flex, then you probably have a defective replacement flex.
"Can you help me verift some components on the logic board?"に関する回答It would help if you explained what you were trying to accomplish, as well as adding a photo of the reverse side of the board. Nonetheless, here are my thoughts: (1) The black blob on the left is a micro-controller that is covered with an epoxy. This will not be a traditional IC with markings, it will literally be the silicon die. Not much you can with that. (2) The metallic probe on the right appears to be some kind of connection or perhaps a switch. To what purpose…who knows. You should be able to figure that out by looking at the toy car it came with. It could be for some kind of switch to activate the sound. (3) The blob in the middle is a solder joint. Again, without a picture of the reverse side, it’s hard to know exactly what it’s purpose is. I suspect it is a third anchor point for the metallic probe on the right.
"iPhone 7 Bootloop after Screen Replacement"に関する回答The 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. 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. 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.
"iPhone 8 plus. image but has no backlight."に関する回答Assuming the replacement parts are in working order and that there are no issues with the work itself, I would consider looking at the DISPLAY_TO_CHESTNUT_PWR_EN line and related Display Control Signals. They are the ones that tell the backlight driver to power up the anode line.
"My iphon 6 plus phone pic bulary and shaking"に関する回答This could be an issue with the image stabilizing mechanics of the 6 Plus Rear Camera. If resetting the device doesn’t help, then consider replacing the Rear Camera. You can do this yourself by following this guide.
"Bootloop after housing and screen replacement"に関する回答Did you transfer over all of the flexes or were they pre-installed in the replacement housing? Either way, you have a ton of variables here and you will need to isolate things one by one. I would start by connecting the screen (just the screen, no FCAM), Lightning Port (from the original housing as it was a known-good part) and battery and then connect to an iTunes enabled computer. Does it boot properly and remain stable, if so, then add flexes one at a time until the phone fails. If not, then try another charge port or remove the screen to see if it stabilizes. Take notes along the way as this could get confusing. This will help you determine if this is logic board related or simply a bad flex.
"iPhone 6S does not turn o"に関する回答I suspect you have a battery issue but follow the troubleshooting guide below to help isolate the issue. When troubleshooting charging issues, I would do the following (in order): (1) Always try another Lightning cable and charger, preferably Apple original or MFi certified units. (2) The Lightning cable 8-pin connector should be sitting flush with the housing and completely inserted. If it is not, there could be lint/dust/debris inside the port impeding a proper connection. You can clean it out with a toothpick, fine point tweezers or a dental pick. Just be careful not to damage the pins inside the Lightning Port. (3) Change the battery. The battery is the weakest link in the entire phone and certainly for charger related issues. It is also the easiest thing to replace. Use a battery utility, such as coconutBattery (for Mac) or 3uTools (for Windows) to test the battery prior to removal. Anything less than 70% of design capacity will require replacement. (4) If the battery is in good condition, you can use...
"Home button stopped working after charging port replacement"に関する回答The 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. 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.
"Repair man telling the truth?"に関する回答You’ve got too many variables here and you need to whittle it down. If the phone boots with your original screen and is recognized by iTunes, then it’s probably not a Tristar issue. If the phone doesn’t boot with the replacement screen, then it’s probably a replacement screen issue. Has the shop tried multiple screens? At this point, find another shop and see if you have the same problem, otherwise, order a high quality replacement screen and try it yourself.
