Back up Camera blue screen

I have 2010 2551 with back up camera.  It has worked fine  a month a go when I went down to the Pole Barn to turn over the engine and I notice the camera only had a blue screen and don't know why.  I didn't take it out for a ride just backed it out of the pole barn to keep the fumes outside. I remember seeing the screen showing me backing out.  There is power but no picture just a blue screen.  The volume, contrast, brightness, etc show ok.  Could real cold weather have anything to do with it. Has anyone had this problem?  I don't have any reference to see what it could be.  Probably something simple and stupid that I am missing! Any Suggestions!
 

Check the wiring at both ends.  It is possible that the connection to the camera of the connection to the reverse light circuit is either loose or broken.  Also, double check your camera/monitor ground connections. A bad connection can cause problems such as you are experiencing.

If the camera is a wireless model it is possible that there is interference from another device which is on the same frequency.  This can come from wi-Fi signals or bluetooth devices, home security systems, cordless phones, and even microwaves.  You may have to move your RV to a vacant area -- away for possible signal interference -- to confirm that the problem is not a signal issue (if using a wireless camera).

Keep checking, and you'll find the answer.

Had that problem on previous 2010 2350. My problem was loose cable connection in rear section.  Cable from camera connects to longer cable that runs to front of pc.  Had to unscrew light below hole where camere cable enters body, pull cable up, push connections tighter, taped them so wouldn't happen again & replaced light.  There's  an old thread on this topic somewhere on the forum.

We have the same problem,  starting last summer.  Never got around to doing anything about it.    Thanks, Imichael,  for the tip,  hope to give that a try.
I see those lights up there are sealed up quite tight with something,  silicone caulk ?

After removing the screws, you can gently pry up on the light and it should come off easily. My first pc was a 2007 2700, and I ran a satellite radio antenna thru the camera cable entry hole down the back and had to remove the light for that, too.

Good to know if it happens to us.  Thanks for sharing.  Was the back up system being discussed, a Zone Defense brand?

I have a different kind of Zone Defense back-up camera problem, hoping someone can help.  Our system has an integrated microphone inside the back up camera but it stopped working many years ago.  The monitor up front has "working" sound.  It was great to hear Irene give me verbal instruction when she stood behind our PC helping me back up.  It would be nice to hear her again rather than trying to hear her yelling from back there, listening through the rolled-down windows.

I will try the tip shared earlier, but maybe someone here has personal experience specifically with the audio portion.

Thanks for the suggestions so far.

Can you give us some information on your backup camera?   Such as, the brand and whether
it is hard-wired or wireless.  Thanks.

Ron.D.   ... no idea how to fix your camera sound. However an easy work around would be a set of FRS radios. A decent set can be had for 30 or less and they take up very little space.   Just a thought.

Hi Joseph,

We have 2-way radios but are always in a hurry to get unhooked from the tow vehicle and quickly get off the campground street.  By the time the radios come to mind, we are just getting it done without them.  Having the sound built into the PC was so very nice.  I'd really like to get it working again.

Model number would help, but I googled 'zone defense backup camera' and got a few pics. Looks like they terminate at the monitor end with red, white and yellow RCA connectors. *usually* the color code is red/white are audio, and yellow is video. A possible test to see if the missing sound is a camera or monitor fault might be to put another audio signal in while the camera is working. If you hear the test signal, then its most likely a camera/wiring fault.

I can set up a better diagnostic test if I knew model info.... ya' know what happens when one ASSumes normal color codes are followed.. sometimes the magic smoke gets out of the wires....

Ron,
Any chance your system is still under warranty?  I'm sure you checked all the obvious -- and the not so obvious -- possible issues which could cause the problem.  I have seen systems with an inline fuse, easily overlooked when troubleshooting.

Time to come up with clear hand signals Ron. We never had sound on our back up camera and we swore we wouldn't yell at each other and entertain other campers (as many of them entertain us) so we started out with walkie talkies but that got old... Batteries died, somehow got on different channels, other people on our usual channel so more time coordinating to a new one and so on. We have clear hand signals and John DOES NOT move the rig if he can't see me. It works for us.

Thanks Cropduster for the suggestion.  Our system is 11 years old now, surely beyond warranty.  I doubt the sound is on it's own fused circuit given the low power the system operates at.

2frazzled, you had me smiling to laughter about your hand signalling suggestion.  We surely do resort to a lots of hand signals, fortunately none are swear words    Irene and I suffer from miscommunication.  Irene's Greek hand signalling can sometimes require interpretation.  When I don't get it right, she starts talking with erratic hand signalling.  The back up camera helped to reduce miscommunication and got us into camp sites much more quickly.  I love that girl and her ways.  That old saying "It's All Greek To Me" applies here.

We use our cell phones.
