Switch does not start

Nice to meet you. I’m Japanese, so I’m translating and posting, so I’m sorry if I make a mistake.
The switch no longer boots. When charged and measured, it is 0.46A.
Even if I replaced the IC of M92136 and the IC of PI3USB, it did not start.
As you can see in the picture, the capacitor on the back of the CPU seems to be short-circuited. What about?
Reflowing the CPU didn’t help. Is there a possible cause other than the CPU? I want you to tell me
I’m sorry if my English is wrong.

Excuse me. For some reason, I can’t post photos
