Hi.
I really looked carefully for ANY leakage since I ran into it before but no=
ne visible.
I disconnected the keyboard right in the house since there has been so much=
trouble too before reving the set.
I will try removing the micro tomorrow and associated componets since I'm a=
t the end of my rope today.
Thanks!
