for over two decades I have been designing a super carbon structure for American and European aviation. I built two engines, a lot of wings these still fly ). and some sport supercars.
Now, after Brexit, I am slightly early retired ... and I'm a bit bored :-) I build drones for my sons, the Cesna Mustang simulator, because I promised the eldest that I would teach him to fly ... it will take a while. I also run a small studio ... repairing apple’s stuff ... as a volunteer in EU studionapraw.pl and video blog on YouTube
best regards, everyone. I wish you much patience and good health in this pandemic time.

hello, in facts: iPhone 6s, no water damage, all is fine but... After every 5 minutes, when screen is off phone is going...

Hello there, The problem that can always happen is the new condition of the battery (this has happened many times). The new battery does not work. So good practice for that problem is to connect the new (Chinese) part before gluing it for the first time and check its condition. Now, try to remove the new battery and connecting the older one. If this fails, try changing (even temporarily) the touchPad and its ribbon. Alternatively, you can remove the new battery and start the computer without - with the power connected. The computer will start if the damage has not occurred before.
Leer máshello Luan, there may be several reasons. One of them is the video port disconnecting from the motherboard, which sometimes happens. However, it is most likely that one of the two backlight circuits (located in the screen, just under the metal support) stopped working due to flooding. You will probably need to replace the screen. Fortunately, if you do it yourself, the price will not be high. A screen in the US can cost anywhere from $12-25. Check it in your loco.
Leer máshello there, Everything points to this. Insert the lightning plug into the port and take a photo of the place where the plug enters the housing. Show here. I'll tell you what to do. Maybe it's just a piece of dirt blocking the port space, it happens all the time (you will see it in the photo - as above). Otherwise, due to the broken brackets of the lightning socket, it will need to be replaced. Unfortunately, you probably won't be able to do it yourself without damage. You can find a good repair shop and order a port replacement. It won't be cheap, but it will certainly be done well and only once (which I encourage you to do). Privately, I am a supporter of repairs on your own kitchen table, but unfortunately it requires a bit of equipment and a steady hand. Especially in the case of iPad repair
Leer máshello there, the information contained in the log (panic.log) confirms the problem with the screen. Communication via the i2c3 protocol to the display-eeprom device has been interrupted. This usually happens when someone messed with the SIP screen and caused a short circuit, as a result of an error when reballing the controller or its damage. Alternatively, the error may come from the same subsystem but on the motherboard side. In the first case, replacing the screen will solve the problem (or improving the SIP soldering). Secondly, check the resistance value for pins #40 and #38 (i2c3_ap_sda_* .500 respectively for each) on the video port. If it is lower by 50%, change the multimeter (reading error) or you are reading incorrectly (diode mode with reversed polarity). Otherwise, it may indicate damage to the bcm15960a0 touch controller, which will need to be replaced, or to the processor itself - which usually ends the life of such a device. (1) fingers crossing,
Leer máshello there, As a result of trying to plug in the touch/screen connector and (literally) run the keyboard-pins over the adjacent pins of port, you introduced 3.8V to the data lines, which receive 0.8-1.8V. In extreme cases (matrix) you sent 12/18V from the backlight circuits to i2c (0.8V) straight to the processor, which usually ends in the death of the device. The good news, however, is that this happens extremely rarely and you have to be incredibly unlucky to encounter such a case. This can only be confirmed by an electrical test and a current start-up assist. If this is the case, your iPad is rubbing a constant current of about 0.20A at startup. It seems to me that you connected the touch power supply to the control line and fried two inductors and a pull-up capacitor - which, due to its parameters, did not break into pieces but directed the 1.8V signal straight to the housing (classic short circuit). You need to analyze it, desolder the culprits, which will bring your iPad back to life - which I...
Leer máshello there, The screen backlight is provided by two independent diode circuits. If one of the circuits (for various reasons) stops lighting, you see a shadow due to insufficient light. You need to open the iPad, check the backlight circuits, repair the damage and close the screen tightly. The fault is rather from the easy and quick category. However, it cannot be done without microelectronics. Alternatively, if the fault is on the matrix side (where the illuminating diodes are located), it is enough to replace the matrix itself. However, such damage is extremely rare.
Leer máshello Ryan, Your problem is a short circuit in the electronics. It happens all the time. In the evening, last looked to see if the alarm clock set, and in the morning... it looked like a dead. Eventually, one of the pull-up capacitors died. Sometimes it is an end of its resorce, sometimes it is an internal explosion due to overload. Stories like this could be told for hours. You can find more of this on my blog (link in the "about me" tab due to the restrictions of this website) if you would like to learn more. Coming back to your case, the problem will be solved by a microelectronics in a good repair shop. Diagnostics will not cost much and will protect you against unnecessary costs and irreversible damage to your phone. Also, it should not take longer than 15-20 minutes, which is enough in skilled hands to solve this puzzle. You are at the stage of a really minor repair, don't let be convinced that it is a kind of difficult repairing... for some astronomical amount of money. It just will mean that the...
Leer máshello Elizabeth, Looks like your phone's back glass has been replaced. It is possible that the glass comes from China and is not an original product - that is, your phone has been modified in some way - using the nomenclature of an authorized service center of Apple. There's nothing inside that would explain the mark. If it is not an imprint of the surface being wiped by the case, then there is only a trace of the suction cup from the production process of the replacement element.
Leer máshello Roland, Isopropanol is a good solution for the phone. Thanks to the appropriate physical properties, it oxidizes and evaporates almost instantly. It certainly won't cause any damage to the electronics. iPhone upgrade is available in batches. Important is the region of distribution and installed internal components, major chips. The fact that one of the three has already been updated can only mean that the other two are lower on the list of system servers (maybe the production date and serial number are also important, which seems to me to be logically related to the above). Check your WiFi connection and make sure your battery has more than 30% charge. These are the necessary conditions to run the upgrade query. Connecting the battery with the screen connected is completely normal - you can't assemble the phone in any other way. It would be dangerous to connect the screen while the battery is connected! It would be extremely irresponsible that way.
Leer máshello lil, This seems very unlikely. In my opinion, you have badly closed connectors: the one from the battery was badly snapped or was pulled out with a sharp tool. Lack of delicacy with such small elements usually ends up in a mess in these areas. Same with Face.ID. A badly closed connector of the tape with screen sensors will manifest itself just like yours. You may have managed to tear a delicate tape, which is also common in inexperienced hands. The efficiency of the battery will return when you unplug the connector again and plug it in again. Check beforehand if something inside is blocking access. It's best to use a magnifying glass or phone camera. Take a high resolution photo because it's really small area. Same with Face.ID. If you haven't mechanically damaged the tape, checking the connection usually helps.

hello Russell
I have my own way: the condition is that the battery is disconnected, this is extremely important. If you place the new screen on the edge of the tablet, its cables will fall freely into the appropriate port. Without pressing, move the connector left/right until you feel something fall into place. Light pressure will make a "click" and that's it. Done. The second one is a bit more fun, but the principle is the same.I have my own way: the condition is that the battery is disconnected, this is extremely important.

Yes, I repair every Apple device at the microelectronic level, iPhones too. In most cases, this can be fixed, however, the details depend on the specific case.Yes, I repair every Apple device at the microelectronic level, iPhones too.
