Amazon Echo circuit diagram?

Hello, I got my hands on a (what it seems to be) water damaged power board for an Amazon Echo, and wanted to try to fix it (Yes, I know I can get my hands on a working echo in Ebay for 40 bucks, but I want to try to bring this one to life). Also I have noticed a lot of users with similar predicaments pretty much stuck where I am, so maybe as a collective we can bring light into this matter? :P

Is there anyone that might have a circuit diagram of the echo power board? There are several components I think I will have to replace (resistors and capacitors), but I need to know the values for them to get the spare parts.

The closest I got on getting information on the power board is this PDF that tries to reverse engineer some aspects of the echo itself, but there is no diagram, only some information regarding test point values.

Here are some images of the trouble areas and the current status:

Thanks a lot for your time!
