Manged to get a hold of an iPad Pro 11" 4th Gen however it does not charge and upon opening it looks like someone has tried to replace the port and knocked a component off but I cannot find a schematic or boardview for this model so was wondering if anyone could help identify what I think is a missing pad and capacitor? Looks like whoever was in here last tried to put it back on with hot air and melted the plastics too...

Thank you so much for sharing this. The yellow pad is missing as well so I'm going to assume where that trace to the left isn't connected to somewhere that the line draws to the right towards what is most probably U22A1 (also very likely under the shield unless i can connect a wire somewhere else). I've got the iPad switched on and it seems to be mostly working aside from the lack of charging which is expected if a trace is missingComment

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... -

by vbogoevHello,
I bought an iPad 4 from eBay which is not powering on and wanted to troubleshoot the problem just for fun.
But the fun ended when I stuck... I don't know what to do next and I'll be thankful for a bit of help.
What I know so far:
Pluging the iPad to the charger charging the battery with around 2.3-2.4A, which is OK IMO.
Pressing the power button does nothing. Press and hold the power button + home button (to reset the device) does nothing (it is resetting but still doesn't turn on).
I dissassembled the tablet...11-19-2021, 04:46 PM -
by ntchickenHi everyone,
My iPad suddenly stopped working and does not turn on and is not detected by a computer. When I plugged it in and measured, it read the following:
5V, 0.5A, 2.5W (both with and without a battery).
I opened it up to look for obvious signs of damage but I can't seem to see anything with my untrained eyes. I took my multimeter, set it to continuity and tested the resistors and diodes for any shorts.
Below, everything circled or boxed in yellow is shorted. Would anyone have any idea what the issue is based on the pictures and how to... - Loading...
