Portable speaker with usb and radio

Hello good day. I have a problem with a speaker of those laptops, with battery. My friend turned it on and began to sound a tic tic tic turned on all the lights blinking. The speaker has the option of being used with battery (which is already dead) batteries (with which it does not work) or direct at 220va (which is the only way I turn on and makes that fault) I opened it and noticed that all plates had too much moisture. To which I cleaned the plates and tried again but still doing the same. Check some resistors and capacitors and they seem fine. What if you notice that the integrated KA2206B. TX332S had too much moisture on it. It may be that this integrated is generating the fault. From already thank you very much.

if taking out the integrated one and measuring the pins with those of mass or ground, it must not mark very low resistance.

On the Internet I only find an equal one that instead of saying tx332s says wx1608gn could change it for that ...

no friend, the main thing is the numbering of the integrated = KA2206B, the other is simply a code.

Take out the integrated one and measuring between the 12 thin pins it has and the 2 thick ones that are in the middle gives me 100k ohm high values and values like that.

Test without the integrated equipment if you continue to make noise.

It has no sound output but the ones that turned and turned off are now normal. As to boot.
