It may possibly be repaired but the problem is in finding the replacement parts.
I couldn't find any replacement parts at all for a Kindle S8IN40 (aka Kindle Oasis 3, Kindle Oasis 10th gen, Kindle Oasis (2019).
Also the only repair guide that I could find (and a failed one at that) was for a Oasis 9th Gen. This model certainly looks like that it wasn’t meant to be repaired.
Kindles are difficult with parts because each new model differs slightly from the previous, so parts aren’t readily interchangeable, between same series models or even different series e.g. Oasis, Paperwhite, Fire etc. That is why the model number is important and not just the model name as even “generations” can be confusing as to which one it exactly is.
Hopefully someone else may provide a better answer.
