keyboard, trackpad, Ethernet (wifi) not working..

so here it goes!

i got this a1342 a while ago, it worked fine except for a couple of keys and the powerbutton. i replaced the topcase with a new one..

powerbutton works now =) But the trackpad, keyboard and wifi doesnt work (external mouse work). The fan is running at the highest from start.

The logicboard didnt have any problems before replacing the topcase, so i have been looking at som schematics to try to find anything these tree things share. I were looking over some ground points thinking that could be it, but al grounds are good. i have been going over the logicboard with a magnifier to se if there are any caps blown but it doesnt seem to so..

So HELP!

I've heard of this happening if you did not use an ESD wrist strap or an ESD mat, or ESD safe clubs, or black stick, or ESD safe tweezers. Micro tears exist in there for sure somewhere. The motherboards are pretty affordable especially on eBay.
