I've had an HDS12 for about two years. Recently, it's been acting as if someone keeps touching the left edge of the screen. It can happen anywhere from 30X per minute to 1X per day.

 

I've tried resetting the unit and re-calibrating the screen, but neither of those has helped.

 

Turning off the HDS7 on my bow might help, but the problem's so random, it's hard to tell.

 

Does anyone have any clue what's happening?

 

What happens? Does a cursor suddenly appear at the left edge and lock the screen?

More info is needed....pics would help.

I'm not near my boat at the moment, so I don't have a screenshot. If I provided one, all you'd see is a cursor on the left edge of the screen.

 

If you randomly touched your screen at a bunch of different spots on the left edge, you'd see the same behavior that I'm seeing. The screen doesn't lock, but it's also not very responsive when I touch it, probably because the unit thinks it's being touched.

If you touch the screen on any Lowrance touch screen product whether it is intentional, accidental, or inadvertently, it will place a cursor at the place touched and the screen WILL stop moving until you finish the command. ie: Clear Cursor, Add Waypoint, Measure distance..etc..etc..etc..

So, is this what is happening to the left side of your screen? It stops and awaits further command? Maybe you have a pic to help me help you.
