mikek753 Posted June 17, 2015 Report Share Posted June 17, 2015 hi, when car is started and put in reverse backup camera displays video feed to HU just fine however, after 20-40 min drive when I try to park and switch to reverse I got black screen with HU warning ... mirrored ... if I turn off engine and wait for a min or two and turn car to ON or start engine I get video feed on HU just fine I tried to disconnect backup camera when I got black screen (car with engine ON after parking against curb and switch in reverse position) and connect video camera / camcorder input to backup camera output and camcorder shows video just file. so, looks like backup camera works Ok and something within HU. Originally I thought that it's backup camera and got another camera and even added voltage regulator as I thought camera might not take over 12V - so it isn't the case. my connections: backup camera takes power from backup lights camera is connected over rca cable to HU HU gets +12 from reverse light to reverse detection wire (I think it's magenta, has label for reverse) HU is set for polarity as battery How I can fix this annoying issue? thanks Quote Link to post Share on other sites
faolmos Posted July 5, 2015 Report Share Posted July 5, 2015 I used to have the same problem when I powered my backup camera to a constant 12v, try this, the ground cable from the camera to the body of the car, and the + wire from the camera to the +12 where yo HU it's connected. What its happens its that you camera constantly its on, and after several minutes it shuts down automatically to protect it self Quote Link to post Share on other sites
mikek753 Posted July 5, 2015 Author Report Share Posted July 5, 2015 thanks for the reply. No, camera in my case isn't powered unless car is in "R" position. So there is no camera overheating issue. please, take a look at my video that shows how 5sec power reset re enables HU camera input https://www.youtube.com/watch?v=z6C19gX-8zU Quote Link to post Share on other sites

greeny129 Posted January 28, 2017 Report Share Posted January 28, 2017 +1 for heat, check you connections are secure/soldered/crimped properly. Quote Link to post Share on other sites
