I'm afraid I don't have schematics for your iPad, but let me tag @flannelist and see if by chance they have a set.
Otherwise all I've come up with so far is gloom and doom from repair.wiki.

***Solution:*** This device is very notorious for having CPU related issues. The board flexes and tends to disconnect traces under the CPU causing this issue. Reballing the CPU can sometimes fix the issue, but the CPU also can just fail altogether. Seems to be a very common defect for this model.[/quote]

Hi JoshR,

Going by the somewhat fuzzy schematic you posted, that cap appears to be primarily a filter to smooth the line its connected to (I can't read the name of the signal on the schematic).
+

As such, you should be able to pull the cap from the board and see if that allows the board to boot. The cap is supposed to appear as an open circuit to DC voltage but if it's overheating that would indicate that its dielectric has failed and it's providing a direct path to ground on the line it's on. Once you have the cap removed from the circuit it should appear as an open circuit on an ohmmeter.
