When you say the 2d is flickering, does it look like interference? Have you tried 83khz alone? Have you seen any of the information repeat itself over and over again?

im fishing in less than six feet of water and using the 2d/360 screen.sometimes the 2d is working ,then all of a sudden it will do one of to things.it will either make these fickers were it disssapears then comes back or it will ficker and then the depth will go to something like 18 ft. and stay that way for awhile.twice the 2d just went to a gray screen,like the way your si was doing.the only way to get it back was to reboot.
