Welcome to the Raymarine Forum PAWDAD,
Some photos would indeed be helpful in identifying the symptoms and then providing a recommended course of action to correct the problem.
I know that this is an old post, but wanted to mention that I frequently see diagonal lines when travelling in my kayak. They are due to gas bubbles released off bottom and rising in the water column. They will always be aligned in a NE-SW axis as you move along. If your diagonal lines are going in a different direction, then they are not due to gas bubbles.
