Answer to "Screen replacement for iPhone SE 2020"Yes, you can replace the iPhone SE 2020 screen assembly with an iPhone 8’s.
Answer to "iPhone 6s plus backlight half display"The backlight is working so I don’t think it is a board issue, because all of the LEDs in the matrix would be off if that were the case. Are you able to test your new display assembly on a different iPhone 6S?
Answer to "MacBook Pro late 2011 17' upgrade"There is a way to upgrade the WiFi to 802.11ac and Bluetooth to 4.2 on the unibody generation MacBook Pro’s! Check out this airport card upgrade if you are interested; it’s a one-man R&D project (hence the price), and currently out of stock due to high demand. I just wanted to share this so you know it is an option. He has a full page of documentation on the system requirements and the install process as well.
Answer to "wont unlock if I have the ear speaker plugged in"The ear speaker component contains a few different modules; the ambient light sensor, proximity sensor, ear speaker, top/front-facing microphone, and FaceID sensor. If just one of them were damaged during the transfer, it may cause a short which will cause the device to malfunction (freeze or reboot). In your case, based on when this symptom arises, I’m inclined to say that the FaceID sensor might have been damaged. It makes sense for iOS to attempt a FaceID scan during the unlock process, which is when your customer’s phone bricks. Before deeming it a bad unit, I would definitely verify that the board connection is free of any dust or debris that may be obstructing it by re-seating the flex, and follow that with a hard reset. If you’re still in trouble, I would then test a known-good ear speaker component and check for the original symptom. If the known-good resolves the issue, the original part was damaged in some way unfortunately.
Answer to "Problems with screen after long time not using"I have seen this before; unfortunately, your LCD has suffered permanent damage. I can’t give you an exact reason why this happens, as there are many, but in most cases, this can be attributed to either too much heat or pressure on the display. If this machine was sitting somewhere that gets a lot of sunlight, or stacked beneath other items for a prolonged period of time, this problem will develop. You will need to replace the LCD or the entire display assembly (whatever you’re more comfortable doing). Sorry for the bad news.
Answer to "Vertical lines appearing on display 3-4 times a day."I would open it back up and have another look at the display FCP connectors. (1) Power off the iPhone (2) Open the device (3) Remove the battery shield & disconnect battery (4) Remove the display assembly shield & disconnect all assembly flex cables (5) Check the pins on all of the flex cables, make sure they are clean (6) Inspect the back of the display assembly, look for any signs of damage (7) Check the pins on all of the board FCP connectors, make sure they are clear of any debris including the surrounding moisture seal (8) Double-check that there are no loose screws inside of the device, and no debris on the outer edge of the frame where the display will rest (9) Reconnect display assembly & reinstall shield (10) Reconnect battery & reinstall shield (11) Close the device (12) Plug in genuine charging cable & perform a hard reset (hold Pwr+Home until you see the Apple logo) (13) Boot into iOS & test the LCD If you verify all of that and are still having issues, there is likely a problem with your...
Answer to "Phone will not power on after replacing screen"With a '''USB mini voltmeter''' you can measure the power being sent to your device. (1) Plug the voltmeter into a powered USB port (2) Plug your lightning cable into the voltmeter (3) Connect the lightning cable to your iPhone (4) Power on your iPhone & watch the voltmeter You’re looking for a consistent amperage (red number) between 0.9-1.0A being sent to the device during boot, and while it is running. If this number dips frequently or stays low, you are not just dealing with a display issue. It could very well be a charging port and/or battery issue. Another thing you can test is the voltage on your battery using a multimeter. If it reads below 3.82V it means that it is not charged, or has failed in some way. By ruling out a potentially bad chargeport first, we can conclude after this measurement whether it is a battery issue or something else.
Answer to "Why is my microphone not working at all?"This is a widely known issue with the iPhone 7/7 Plus models, it has to do with the Audio IC which is a chip on the internal logic board that is prone to failure. The only “fix” would be an experienced technician successfully jumping a pin on the chip using specialized micro-soldering workbench tools. This is not an issue you can throw parts at to repair. Apple will not acknowledge the issue, but they will treat it as a whole-unit replacement when you bring the device to them. If you have AppleCare+ coverage on your device, you are covered. I would not take this to a repair shop unless you absolutely trust the technician working on it. One slip-up during a job like this can render the phone completely useless as the tech can break plenty of other fragile components on the board if they are not careful. One workaround to the problem is using bluetooth headphones, if you do not want to spend the money to fix it.
Answer to "Replacement battery - laptop randomly goes to sleep"Quick question; did this symptom occur even before replacing your battery? Here’s what you can try: (1) Navigate to About This Mac and open System Report. (2) On the left side of the window that appears there will be a scrollable column where you will find a section called Power, click that. (3) This will give you more information about the new battery, take a screenshot of it and post here. With a new battery, you should expect a very low number of charge cycles and its condition should read “Normal.” If you calibrated it correctly, it should have an accurate reading of “Full charge capacity” too. This is an important follow-up procedure after installing a new battery because it will verify that you received a good unit. EDIT: I should also mention we are looking at the amperage and voltage of the new battery as well. All of these units are tested before shipment, so I doubt it is the issue but still a possibility that needs to be ruled out. Once verified, I would check your Energy Saver settings located...
Answer to "Why is my camera not working on the A1932 after a screen repair?"I would double check the flex cable connection from the display assembly to the logic board. Take a look at the pins on the flex, and the pins on the FPC connector (where it connects on the logic board). Make sure they are both clean and free of debris. Once that is verified, I would attempt an SMC/PRAM reset on the device. (1) With the machine off, plug in your charger (2) Hold down Shift+Control+Option+Power (3) Release key combination after 10 seconds (4) Turn the device on (5) Hold down Command+Option+P+R (6) Keep holding, wait for the second startup chime and then release (7) Allow the device to boot into macOS (8) Check your FaceTime camera again
