Anyone had a similar problem with the above plotter?
Switched it on yesterday, not having been used for a few weeks as I am away on commercial boats most of the time these days. Display unstable with lines and blank spaces flickering across the screen. However after leaving it switched on for a while the display gradually became more and more stable , eventually back to normal working display. Its done this to a lesser extent in the past and we thought it just didn't like cold weather-but now beginning to think its down to lack of use and possibly down to an internal battery problem. Whatya think?
Sounds like the start of a failure. Could be corrosion on the plug/wires at the back or internally. Could be a slight build up of moisture inside causing problems ont eh circuit board. Although they are waterproof, they are not vapourproof and will absorb airborne moisture as they heat up and cool down.
