I am going to try that first and let you know. I actually just purchased the XLV knowing it had this issue so I am waiting to get it home to start working on it. The previous owner had it diagnosed awhile back and was told the perfect pass was malfunctioning and either needed repair or upgrade. He didn't want it down for repairs so he just put up with it. Just trying to get a head start on it and see if anyone else has the issue.
