E120 Classic screen goes dim even when batteries are full
Our E120 MFD has served us well for 7 years. During this time we have always had a problem where the screen goes dark or blank for a few seconds and then comes back on. We were told that this is an voltage variance problem. We seem to have the problem only when it has been on a long time and even when we have been motoring and the batteries are fully charged. One thing that seems to be the case is that the unit feels very hot whenever this happens. Is there a fan or some sort of cooling that might not be taking place. This year we are in Chile where it is much cooler and the screen blackout has happened less frequently but always after the unit has been on for a long time. Any ideas????See More
