Hi. I recently changed a charging port on a Moto Nexus 6 with success on the port but major fail keeping microphone functionality. Thought I was aware of the closeness of the mic to charge port when soldering and I thought I was careful unfortunately the mic is now not working and Im honestly not sure where I went wrong. Everything was taped but i guess it is possible that some flux or alcohol got in from under the tape. None the less I can use insight on what i did wrong and some assistance finding the appropriate parts for microphone functionality, and maybe a schematic for this phone if anyone has access to it. Thank you all in advance. I

Hi Everyone,
Please, I have a MacBook Pro A2338 M2, board number : 820-02773. The speakers and the microphone of the Mac are not working and I need assistance in fixing.
UR730 got damaged and short-circuited the motherboard. After removing the shortened IC; before and after putting the new one I ordered, the speakers [specifically the other one not affected by this IC] and the microphone are still not working. I do have sound through a Bluetooth speaker device or when I connect a headphone with microphone to the jack 3.5mm input. Also, media files do not play unless a... -
Hi,
I have an external CCTV microphone photos attached. The two cables (green and blue have come off the little microphone chip) however the pad has gone off the chip when someone dropped it.
There are a few metal bits poking up but solder wont attach as the pad has gone. Is there a way to repairing it? (I can solder) I was thinking of trying to attach a trace pad to the metal bits to see if it joins.
I have seen online some of them have the copper pads further down. Could I scrape the top off and go straight to the pad that way?

Hello everyone,
i was reballing the power manger of a moto g84, after applying heat i tried to power on and it wouldn’t.
i injected 1.5v to some capacitor that seem in short because both side beep if tested.
when i inject i feel the cpu burning;
since the cpu is exactly on the other side of the board, is that possible that the heat from the reballing damaged the cpu? do you know where i can find schematics or what can i do?
i know this is not enough to explain the situation so if you need any other info ask me please!
Thank you very much in advance11-08-2024, 02:13 PM -

Hello ,
I have a MacBook Pro A1990 , year 2018 board number : 820-01041A.
The speakers and the microphone of the Mac are not working for some reason.
I do have sound through a Bluetooth device or when I connect a headphone plus microphone to the jack 3.5mm input.
Can anyone give me some direction on how to debug it on board?
thanks
