Why my doesn't my bluetooth work anymore?

Hello guys, last year I let my JBL E40BT get wet in the rain, and since then, the bluetooth doesn't turn on and only works with p2/p1 cables. I noticed that the ic controller (24090) was a little oxidated, can this component cause this problem? I'll buy another ic to test it, but I want to be sure that it is only that. Can anyone help me? Thanks a lot!!
