iPad A2316 - No Power - Previous Repair Attempt

iPad is presented to the repair shop with no power, having been diagnosed as a motherboard issue by a different repair shop.

Upon disassembly we have found that the device has a broken battery connector, a damaged battery, and ripped digitizer cable.

Damaged Flex cable on digitizer

Battery bent, still functional.

The battery connector is clearly damaged and missing pieces

Outside of that, we also found the charging port to be burned and shorted out.

Burned charging port, likely liquid damage.

We believe the original problem to have been the damaged port, which shows signs of possibly being liquid damaged.

It’s shorted out, and burned, and that device would need a new charging chip and Charging Port which we would be able to replace. We are pretty confident that the device will power on and will function enough to retrieve important data.

Considering the condition of the device and the fact that it’s here for data recovery only, we can likely get that battery connector bent back in place to make contact without replacing it. The battery will be temporary use only. The touch screen may have dead spots , but should be functioning enough to retrieve data. If the screen has bad touch and not able to be used enough to retrieve data, We can offer a temporary screen just to back up to iCloud, which needs to be returned when backup is completed.

UPDATE:

Found additional damage by the loudspeaker connector.

Replaced charging port and device pulls .02 amps at 5v.

Replaced USB CONTROLLER IC CD3217B12 and still same response.

Replaced 343500394-A0 and device powers on, shows that’s it’s responding to charger.

Battery connector was unable to be bent back into place, not maintaining contact with battery data lines , internal pins likely damaged. Device will not stay powered on for data recovery, replacing battery connector is necessary.
