Details

On the 2017 iPad Pro 12.9-inch, a dead board or a screen that misbehaves for no obvious reason can come down to one of its power management chips. This listing covers the 343S00117, one of two 132-pin parts sold for that iPad.

It's listed for the iPad Pro 12.9-inch 2nd gen (A1670, A1671), with a pin count of 132. Because the 343S00090 is listed with the same details, check the number printed on your chip before ordering.

Faults that can involve it

No boot with battery and connectors ruled out.
Display or touch problems with good screen parts.
A rail shorted at this chip.
Liquid corrosion around it.

Doing the job

Locate the chip in your board view and confirm the rails it supplies. Preheat the large board, remove the old part with a controlled profile, clean the pads and fit the new one with fresh flux.

Measure the rails before full assembly, then test boot, screen and touch. When everything checks out, the tablet can go back together with fresh adhesive for the screen.
