Razer Nommo Chroma - Suddenly not powering on?

Hi all, I've got an older pair of Nommo Chroma speakers that have worked flawlessly out of the box since I bought them a few years ago. However, recently I attempted to power them up and nothing. Using a meter, I've confirmed 100% I'm getting power from the AC adapter, but regardless the speakers won't turn on. Is there any kind of hard reset or any other options I can try here? It's obviously out of warranty at this point, but if there's a way I can resolve this without just buying new speakers that would be ideal. Thanks in advance.
