Any idea where I could purchase a QFN8 to DIP8 Adapter that will fit a bios chip off the 820 00875 board. The only one I...

I got sent a mac which had the U5860 temp sensor torn off along with all the pads on the board. It would take ages to boot...

Would someone be able to tell me the orientation position of U5860 on the 820-00239 logic board. I can only make out a...

These symptoms are typical of an IPhone 6 plus. The no touch would be a broken trace under the touch IC “Meson” This is fixed by lifting Meson, running a short jumper wire and replacing Meson. The “searching no service” would be caused by a broken trace under the “baseband CPU” This is a lot more difficult to repair. These faults on the IPhone 6 plus are caused by a drop and or flexation. As the IPhone 6 plus is getting on in age it might be more economical to upgrade.

I think you are getting confused with the ambient light sensor and the proximity sensor. The proximity sensor is there to detect when the phone is up against your face, putting the screen to sleep. The ambient light sensor is used to adjust the brightness of the screen in different lighting scenarios. This is the one that has the filter paper. I have never really noticed if this makes a difference if it is there or not on the black screens. If you think the ambient light sensor is not working correctly due to the filter missing you could just cut a piece of filter paper to pop in there. I have heard of people using a white marker but I am not sure of the results.

Unfortunately this is not an antenna issue. If your Wi-Fi is greyed out there is a problem with your Wi-Fi IC on your logic board. This is not an easy repair and will have to be completed by a competent microsolderer that also has access to an IPhone 8 NAND programmer in case the Wi-Fi chip cannot be reballed and has to be replaced.

It has obviously suffered electrical damage. Maybe this occurred from miss aligning the screen connector or trying to connect the wrong model screen.  As for the damage it has caused it would be hard to determine without a physical examination. If you smelt plastic burning there is a good chance you will need to replace the FPC connector and probably a filter at best. Unfortunately this repair will require microsoldering.

Error 9 can be caused by a lot of things. Jessa has a video on it that you might want to watch. What causes iTunes error 9?

Unless the home button has suffered physical damage from the drop it should still work fine. However to be 100% sure you will need your phone to boot.  So you don’t really have any alternative but to replace the screen. If it still won’t boot you could check the battery and dock, other than that you will need it looked at by a repair shop.

When I have a phone that arrives like this its always one of the following components. 1.       Battery. 2.       Battery connector. 3.       Tigris.

If you want the communities help diagnosing your phones problem, you will need the following equipment. ·         Schematics diagram for the phone. ·         Board view software. ·         Multimeter. ·         Microscope. These are only for diagnosing the problem. You will need more equipment for the repair. I recommend trying another screen first in case the damage was only applied to the screen.

·         Did you remove the screen while replacing the battery? ·         If you record a voice memo can you hear it through the ear piece speaker? ·         Is your front camera working correctly? If you could here on calls before you replaced the battery and you removed the screen while doing so it would point to the front camera flex assembly. Check if the connector is seated properly into the connector.

Yes they usually say with or without fingerprint. Not sure what the price difference is. You could get one without fingerprint ID and purchase a JC home button, it wouldn’t give touch ID but the return to home would still function.
