backup cam

Hey all, anyone having this issue as well? My stock backup camera goes completely black but I see the distance markers when in reverse. It works here and there but the majority of the time it just turns black. Sometimes I get some lines in the display too. Have the stock Alpine system...

InCase anybody’s wondering, About license plate bracketed back up cameras, They are very easy to install on a tire rack as well. Works great integrated with any stinger system heigh 10 series. Took me all of 45 minutes or less
