2018 backup camera failure?
 

Just finished up wheels and tires on my wife's new anniversary present. Went to back up today, mid backing camera went completely black. It came back on and I cannot get it to do it again. I have ext warranty but I know if I can't get it to do it on command it probably wont get fixed. Any thoughts? Oh and yeah here she is looking all badass.
