My 797csi is only showing the right half of side imaging. Left side is blank...also the 2d color display seems to missing information as well...sporadic colors top and bottom in full screen view.....depth reading is sporadic as well. Don't have anyone on the dock that has 797 installed so I am unable to see if it works on their transducer. Is there a good hardware reset that can be done...or is the back to default the only option? Was pressed for time yesterday and didn't get to play around with it much.
Thanks
