@swedtech the picture of board #2 was hopefully taken before you cleaned it. there is plenty of corrosion that can shorten out any component. You must remove the EMI shields if you really want to clean the board. Only after that can you properly evaluate any damage.

For board #1 it would help if you can tell us how you  shorted it out from the AUX from surroundsystem. Let us know how you connected it. You did not tell us if it gets recognized by your computer when you plug it in. You remove the EMI shields and take a look at all the components.
