Hi, have a big problem. I can not start my EFIS D100. It has been on my plane since 2008 and then worked great. Sold the plane in 2009, but bought the aircraft back 4 months ago due to damaged wing. Now the plane has been renovated and ready for approval. My problem is that I do not get into Dynon ... It comes up with Dynon's image with logo. No matter what I'm pushing, etc., it will not. Power and everything is in place. It has been out of power for almost 6 years .. Who can I do ??
