ZX350.4 refuses to work. Halp! (Amp guts pics incl.)

Can't figure out what's wrong with it. It turns on and gives you the green light. And once you start cranking up the volume and get to about 7/33 on my head unit, the amp cuts off and resets. I've checked and rechecked everything, even swapped it out with another ZX350.4 (which worked fine), and this one refuses to work. So I took it apart... nothing peculiar on the board that I can see. Only thing that struck me was the white coating on the bottom of the input board (last pic)

Any ideas?

Send it in to kicker and have them test it out.

They are quick and fairly inexpensive, even if they have to repair it.

Anyone else have a guess?

Bump for the addition of pics of the underside of the board.

Is this amount of corrosion (or whatever it is) unusual? If not, how do I clean it?

You can clean with isopropyl alcohol. I would rule out that it is the amp that is the issue also. Plug an ipod or something into the amp, see if it still cuts out.

Tried an iPod, still didn't work. Like I said earlier, I swapped in another ZX350.4, and it worked like a charm.

Cleaned it up a bit, put it back together, and it still won't work. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
