My display was doing the exact same thing but only during and after it had rained. I cut the rubber insulation away from the sensor where the cable enters the metal barrel of the sensor. Worked some permatex into the gap between the cable and metal barrel of the sensor. Wrapped electrical tape around the joint while the permatex was wet.

It has been raining everyday here in florida and since I did the fix I haven't had any problems.

The joint where the cable entered the metal barrel looked tight but I guess enough moisture was getting into it to send the display nuts.

Maybe this helps.
