Home Theater Questions? Ask a Technician for Answers ASAP
Hi and welcome to JustAnswer, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.Bear with me as I review your concern.
Initially, which fuse was blown? Which part/section got wet?
If comfortably able and feel safe to do so, are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even a soldering iron?

Yes please. The above tests would work with either completely/electrically dead HTR-5540 or "...would not turn back on..."
I understand and appreciate the update.
I also realize that the earlier information may perhaps be not what was expected. Unfortunately, there is no quick-n-easy fix and neither is there a workaround; sorry for having to be the bearer of bad news.
