Went out last Tuesday (5-24-16) and everything was working fine until we had a storm roll in on us. Loaded the boat and unhooked HDS 7 to put in truck while we waited out the storm. An hour later we hooked unit back up and unloaded. Turned unit on and came right up. Then the sidescan quit advancing just sat there with the last image. Turned unit off and back on. Never could get the sidescan to work, downscan worked fine. Decided to disconnect unit and look at the pins to make sure I didn't bend one when I put it back on, all looked good so I hooked it back up and after about 10 minutes of messing around with it, it went back to working just fine. Now yesterday (5-29-16) I went out since it was my only day off this week and turned unit on and everything worked fine, about an hour in the downscan quit working on me. Downscan shows nothing but a white screen. I powered down and back up and nothing. disconnected unit and reconnected and still no downscan. Sidescan was working just fine. Can someone give me and idea as to what is going on here. I'm new to Lowrance and these units. I know it has to be something commend with the scan part of it.

Unit is not networked and I am running the LSS2 with standard transducer. 2D worked during both issues.
