    iPad 6th gen A1893

    Hi everyone,
    I'm looking for the board view and schematics for A1893 cellular iPad 6.
    I removed the motherboard and did a charging port replacement on the device and and I put it back together the power button works but not the volume buttons. I then replaced the power/volume flex and this didn't have any affect on fixing the issue. Is there anything you would suggest? The client also didn't mention anything about this when it was dropped off.
    Any and all help is greatly appreciated thank you.

    See attached. This is for the 820-00996 / 820-01327 logic boards.

    Confirm that the filter parts (ferrite beads) are not damaged or missing.

    You can do a resistance check from one side of the connector to the other side of these 3 coils.

        Could you upload the schematic and components pdf?

            Never mind dears. the component is a 4.7K Resistor & it's for the ENABLE signal of this Tristar. This is why the iPad was not charging. I soldered another one & all works fine. Charges well & iPad works fine. In the near future I will load a jpg & list the components with their values by the four side of the TRISTAR chip because many of the tech replace the Tristar & knock/blow out off components accidentally. Thanks

              Hi all,
              I'm trying to fix an IPAD 6, 2018, A1893 WIFI.
              It does not turn on and does not enter recovery or dfu mode.

              The device was working before, but did intermittently reset.
              I gathered two panic logs:

              Vizio D65x-G4 Volume changes on its own
              by karthur
              On this Vizio D65x, the volume will change on its own. I don't mean like during commercials where the volume will increase. I mean its like the (+) volume button on the remote is pressed and the actual volume dialog is displayed on the screen going up. It will do this, then the volume may start going down. It might go all the way to "0"or it might stop at a different number, then start going back up. The whole time its doing this, the volume dialog is shown on the screen.

              It wont do it until it has been "ON" for 20 or 30 minutes, so it does seem to be heat related....

              Apple iPad Pro 3rd Generation 12.9" (A1876) No Power/Charge When Screen Is Connected
              by grimacelord
              Hello.

              Working on an Apple iPad Pro 3rd Generation 12.9" that has a weird issue. When the display is NOT connected, the iPad will charge and power on normally. I know it's on because I can hear notification sounds and the charging notification sound.

              If I connect a brand new display to the logic board, the iPad will not turn on at all. When I connect the iPad to an 18W wall charger and a USB-C ammeter, I can see that the iPad is attempting to charge, but constantly "resets" after just a moment or two.

              For example, when I connect the iPad to...
