Customer Question

I have a Lowrance HDS7 Gen2. After awhile I am getting a blank screen with vertical lines. By memory I know where the touch screen buttons are and it seems to change but no screen is showing accept the lines. I can turn it off and back on again and it will work for awhile then goes back to the lines. Does the same thing in and out of the water.
