Samsung GT-i9105p water damaged won’t power on?

Folks i opened this thread after i tried every other solution i found on the net. But nothing helped. I assume it is the same short circuit problem as on the i9100 but i could not determine which components are the problem because the chip and the capacitor which cause the problem on the i9100 are totally on different places. Can someone of you tell me what can i do?
Thank you in advance
