Antwort auf „Compass not working and gyroscope inverted”Are you sure you are talking about the iPhone 6S? There is only one version of the logic board (no Intel vs. Qualcomm like on the 7). You might want to check Phosporus U3020); it is right next to the NAND. While it is the barometer and not an accelerometer, the 4 sensor IC’s do all interact. Look up the voltages and inspect for trace damage or dislodged components near the NAND and on the reverse side.
Antwort auf „Touchscreen not working even after replacement”Screen issues with the iPhone 6S series are almost always screen related…except in this case you have a water damaged device. Water damaged devices tend to be unstable and they will develop all kinds of secondary issues. That’s why most micro-soldering shops won’t fix them for the sake of the phone. Try a known-good screen or conversely, put your screen in a known-good device to see if the fault follows the screen or logic board. There could be an issue with the touch/lcd related power IC (Chestnut) which may be repairable if the corrosion is limited. But if that circuit looks good then you have to consider calling it quits before this device sucks all of your time and energy out. Personally, I find the 6S series water damaged devices to be the most challenging.
Antwort auf „iPhone x in reboot loop”Has this phone been in contact with water? These symptoms sound suspiciously like a water damaged device. The other possibility is that of the phone was dropped and the logic was damaged. The logic board in the iPhone X is flimsier than in previous models and this could be a cracked solder ball along the interposer or underneath an IC. If software resets/restores don’t work, you should consider having this looked at by an experienced micro-solderer.
Antwort auf „Black after screen replacement, but the battery symbol is visible.”Sometimes a partially damaged backlight filter can have these symptoms. It will work in low intensity settings, like the battery charge symbol but not for high intensity like a regular screen. Read the rest of my answer below for the full context… It’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,...
Antwort auf „iPhone completely dead, shows no signs of life”The phone requires a battery to boot. 3.7V should be enough to get the phone to start but I suspect your battery has no current driving capacity, even if it shows 3.7V and an iPhone requires a lot of current. Start by trying a new battery to see if that solves your problem before changing the port.
Antwort auf „iPhone 6s: empty battery after ~8-9hours idle time”This could be a replacement battery issue. If the old battery was still decent, I would install it to see if the pattern is the same. If it is, you may have damaged something during the repair. If they have different characteristics, then it’s probably a bad replacement battery. If this is an iFixit battery, then you should contact iFixit Support and they will help you sort things out.
Antwort auf „Snooze'd my alarm, woke up to overheated phone with black screen?”Spontaneous component failure can and does happen. Heat is the giveaway that something shorted and damaged the logic board. You’ll just have to treat this as a “dead phone” and apply typical board-level troubleshooting for this kind of failure. Don’t you have another account on iFixit?
Antwort auf „fixed my phone now it shows the high temp advice.”There are multiple temperature sensors inside the phone. One of them believes the temperature is high and is giving you the warning. Does the warning state what part of the phone is hot, like say the camera? A defective charge port could be an issue so you could always try to plug in the original charge port (no need to fully install it, just disconnect the new one and overlay and connect the original). Because you have damaged the battery outer layer, you may have also caused some additional accidental damage. A close visual inspection, preferably with magnification is needed. If nothing obvious stands out, you may want to consider having this looked at by an experienced micro-solderer.
Antwort auf „Phone restarting after charging port replacement”A defective replacement charge port is always possible. But the fact that it had coffee in the charge port is the smoking gun. There is clearly some water damage on the logic board. Ideally, you need to remove all the shields and closely inspect the board, clean any corrosion with >90% IPA (preferably an ultrasonic wash in EC) and then troubleshoot the corroded areas.
Antwort auf „Glitching screen but responsive to touch (with screen recording)”This looks like a damaged screen. You can replace it yourself by following this guide.
