I have had my Panasonic CN-NVD905U Strada and from the first day it would cut off and then right back on for no apparent reason. I took it back to the store where I had it installed numerous times and the same problem. Finally I had to send it in and got it back and they said it was fixed. But to my luck it is doing the exact thing. Has anyone experienced this problem? Is it bad wiring, and should I take it to another store to get an opinion?
