It seems like there may still be some underlying issues from the water spill. Despite the keyboard being replaced, there are still abnormal symptoms such as no screen, no Mac chime, and no touch bar. It's possible that there might be a problem with the internal connections or components.
I would recommend taking the Mac to a professional repair service or an Apple Store for further diagnosis. They have the expertise and tools to properly assess the situation and identify any potential hardware issues. They can provide you with a more accurate assessment and guide you towards the best course of action for resolving the problem.
