Jensen dashboard multimedia issues
I have a Jensen multimedia JRV215N system in my Jayco class C. In the past the system would come on intermittingly by itself while parked at home with no shore power connected. I was checking on it when I would be outside to make sure it was not on. Sometimes it was sometimes it was not???? Now to the current time. I was getting ready for a trip so a couple of weeks ago took the RV out for a spin around the local area. Everything was working fine even the dashboard system. Then on the day we were getting ready to leave we got in and the battery was dead so we proceeded to jump it off and when I got into the RV I noticed the dashboard system screen looked like all snow. Nothing was working, radio, CD player, however the cameras where working fine and I could see on the screen the sides and backup areas outside. Did I blow a fuse or was it fried somehow?? Any ideas on how to fix this problem?
