Zoom H4n Pro won't turn on?

Hey all,

I recently unearthed an old Zoom H4n Pro from high school, wanted to use it for a project. The batteries inside had corroded so I removed them and cleaned off the zoom as well as I could, but every time it would turn on it would freeze on the loading page. Direct power works fine. I tried cleaning the corrosion off more and now battery mode won't even turn on. Any advice?

When you say 'Direct power works fine', if you can get to the menu screen, try a factory reset if you haven't already.

I did, and I think beforehand it was boring and then freezing but afterwards it wouldn’t even turn on?

Had one of these years ago that wouldn't turn on. Apparently the OS had become corrupt, and there was no option besides sending it back for repair. :-(
