I had the same problem as you seafari and the only way I could correct it (even for a little while) was wiring the DSM straight to the battery. The DSM are very voltage sensitive. Of course then you also need a switch in place to turn it on/off when you leave the boat or it will drain the battery (don't ask how I know). This corrected my problem about 70% of the time. It still happens occasionally.

To be honest I finally just said the heck with it and bought a Humminbird side scan unit...never had a problem with it and now I rarely turn on the DSM at all. Hope you get it fixed.
