Hi. Thought to share a recent repair on the iPAD PRO A1876 that was flaky / not charging.
Issue was a defective dockflex charge cable.
See attached pix on the original connector condition.
Sourced a fresh cable from here:
https://www.esourceparts.ca/replacem...ad-pro-11.html
After the replacement - the display was dark and we almost were in a panic. The charge current was around 40mA @ 5V which is too low for this unit. Confirmed with multiple docks of the power adapter we have in the lab.
Then attempted to use iTUNES which reported to find the iPAD Pro but stated we were stuck in DFU mode. As the screen was removed, we proceeded to restore the IPAD to factory defaults (ok'd by the end customer). All went well after this step.
The current draw > 1A @ 15V and we heard the charge chime a few seconds after the next power up - even without an attached display.
All good !!
If the charger cable did not resolve the issue, the next step is to replace the TRISTAR chip on this Type C connector logic board. Note that the tristar chip on this board = 610A3C. This part is still rather rare on the market.
Found this great article that claims it is ok to replace the 610A3C with the more common 610A3B mux from NXP:

Apple techs had told this iPAD owner to scrap this 2020 model and buy another.
