Sounds like you know the issue is within the I/O board or the I/O cable. I would replace both!

@molla - Well you've already done the hard part! If you really don't want to venture any deeper then its time to get your system to someone with the skills and access to the parts.

I wonder if there is a way to clean the board or just buy a used one

by

Why do you think cleaning will fix this? You have a short somewhere either the cable or the board its self.

I dont know, and thats the reason Why i ask. I thought the oxide some where could cause the short. Anyway, i put out the board and cleaned it whit alcool, it doesnt work.
