I did do something on that order but just the usb and below, not going to say what chemical though. I did clean the 4 balance connector joints the first time with a q tip and alcohol but that must not have worked. OK here's what I cleaned it with, twice, then duster spray. http://www.ebay.com/itm/NO-CLEAN-LIQUID-FLUX-FOR-PS3-YLOD-XBOX-360-RROD-REPAIR-/130498300452 Something was draining #3 I guess I'd better mention that the area that I was concerned about it conducting is between pin #3 and pin #2 on the board underneath the white plastic balance connector.
