I've never heard of this before so I don't have any advice other than to call Lowrance Customer Care or look on Lowrance.com in the FAQ's.

You should check your boat for the common problem. There is something on your boat system that creates this problem.
Maybe the next time this happens, turn everything OFF except the sonar and see IF the image clears up. If it does, then it's just a matter of 'test and eliminate'. Time consuming but everybody can do it. Not likely it is the MFD, because you said it happened in the past with another MFD.
