some parts of dash and display panel not working

Our 2013 Moomba Mobius LSV starts right up no problems. Over time though the horn, front left panel where the stereo, ballast bag fill, bilge, blower etc stopped working. Someone on here said to hit the small red button next to where you turn the battery on and off. IT TOTALLY WORKED!!! We had called around looking for an electrician or fuse that may be out when all along it was an easy fix. THANK YOU!!!! We have not however been able to figure out why the main, small & square display went out and has not returned with this recent fix. The display I am referring to is where your hours are logged etc. Any ideas??

My husband and I are SO THANKFUL for this forum as we are boating enthusiasts but are about as handy as a rock. So, for us it's true what they say.....if you can't work on your boat yourself it very quickly becomes a money pit!!
