Chosen Solution

I left my speaker out in the rain and now it no longer works. It charges up but does not turn on. All I see is one little light at the bottom in the middle but no sound. Megaphone and line in doesn’t work either. Any thoughts?

Teardown that speaker and look for corrosion on the boards and cables. Ifixit article for cleaning reference. If anything send some pics and let us know how its going to assist further. Good luck.
