Intermittent camera? Or monitor?

We left for a week in the 3051S today. After taking off I turned on the "rear view mirror" monitor. There was no picture but an occasional flash of light. As i tapped the on/off or other buttons sometimes it would beep like normal, sometimes not. The turn signal cameras worked a little. Not all the time. Some times after :30 or so delay.

We were only going 65 miles today so I kept going. But blind to the rear. Hated that.

Suddenly at 45 miles into the drive the rear camera just came on. From that point on the turn signals worked and the whole system worked normally. After we arrived at the CG I turned off the RV and when I started it again everything worked normally again as well.

I'm totally at a loss about what this could be. Anyone got any ideas?

Well start with all connections. The box for inputs is on left side under dash. I always start with what would be the simplest thing

Here's today's Camera antics - We started out this AM with the rearview camera showing a blue screen and "No Signal" typed in large letters. Left and right camera's worked perfectly.

This lasted for one hour as we drove 65 miles. Suddenly it all went dark and nothing worked - a few flashes of light but no side view camera's at all. No blue screen and no "No Signal" message. Nothing.

30 miles (mins) later as we were driving suddenly the rear view image came on and everything worked normally for the next hour. Turned off the RV at the State Park check in and when I restarted the RV the rearview camera worked normally.

Let's see what happens tomorrow. I'm taking bets on Blue Screen/No Signal being the way the day starts. Any takers?

You may want to try a hard reset; Pull out the panel under the steering wheel and on the left side of the wheel shaft is the multiplexer. Pull off the wires for 30 seconds and reattached.
The multiplexer is the grey box in the photo.
I read somewhere that the connections tend to work loose. Hope this solves the problem.

Creativepart, here's the manual.
http://www.rearviewsafety.com/media/...r_view__jk.pdf

Note they have propriety cables and because FR used a different side view camera the cable from the multiplexer to the camera has a special splice where they switches the wires. But that shouldn't be an issue. If the cable connections aren't the cause, then it may be multiplexer.

i thought I'd update this saga. This problem continues. And in the exact same scenario too. NO SIGNAL blue screen for 1 to 2 hours of use. Then a Black screen for about 30 mins and suddenly the rear view camera appears and everything works normally.

I incorrectly assumed it must be the Multiplexer - that silver box all the cameras and the monitor plug in to. Rearview Systems was kind enough to send me a new multiplexer to test this assumption. But that proved to not be the problem.

When I plugged the rear camera into any port of the multiplexer that port shows NO SIGNAL. When I plug one of the side cameras into the rear camera's port (#3) and put the RV in reverse the monitor shows the side camera just like is should show the rear view camera.

So, yesterday I decided it must be the rear camera itself. RVS says that there is a "short" (up to 6') hard wired connector in the rear bulk head behind the camera and this is plugged into a 66' extension cable that carries the signal forward. So, I removed the camera and carefully pulled on the hard wired cable.

My thinking was I would immediately find the connection from the camera to that long extension so I could remove the camera and try a replacement camera from RVS. But unfortunately that hard wired cable from the camera ran up into a hole in the rear cap and apparently up in to the roof of the RV. I could not pull the cable down to get to the connection. So, there was no way to get to this connection and hence no way I could see to remove the camera.

You'd think that Forest River would want that camera to be easily removable for servicing and they'd put that hardwired/extension connection directly behind the camera or make it easy to get to. But apparently not.

Has anyone done this on their own? Replaced a Rear View Camera? If so how did you get to this connection.

Sorry to hear the camera cable was not accessible. I hope my suggestions helped you isolate which device was the problem.
Maybe accessible from rear upper cornice? Best to let the dealer tear into that if still under warranty.

I thought it might be in the cornice but when you remove the camera and a couple of the clearance lights you can see in and it's a flat metal wall. The depth is about 2 to 3 inches. And there is a metal top plate as well right above the area with the wires for the clearance lights and the camera cable.

There is about a 1" size hole in that top plate and the camera cabling goes up into there. When I tug on the cable it comes out about 4" but that's all. No sign of the connection to the 66' extension cable.

Just out of curiosity, have you looked in back and under the wardrobe (pull out drawers) to see if the cable runs there?

In reading the RVS description of the camera, it can be ordered with cables of 6"" to 66' with the default being 66'. So your camera can have a 6" connection or go the entire length of the MH using 66'. Maybe Joshua Cavett can check and see what's used and the routing for you? What a job that would be to pull new cable.
Maybe if you contacted the FR warranty agent for Texas and see if they can OK a local RVS camera installer in your area that can replace the camera and just splice it in at the rear. Or better yet, the rear camera may come apart and the wires are just attached with lugs. RVS may have a better solution for you.
Frustrating, I know!

I keep hoping Joshua will chime in, but no luck on that.

I have set up an appointment at the nearest Forest River dealer - they are only about 30 miles away. But it's a very large dealership that can take over a month to get an appointment. I got "lucky" and the day I called they had a cancellation So, I only have to wait 2-weeks to get it in. However, we leave on a month long trip to Albuquerque, Durango and Santa Fe on the 18th of May. They usually take 2 to 4 weeks for any warranty repair. So, I was hopping to find an easier and quicker fix.

The 3051s doesn't have any drawers in the wardrobe - just shelves and I see no wire looms running through there.

If you look at the photo on the cover of the Product PDF the camera is shown with a few feet of cable and a longer 66' coil of extension cable. When I looked at ordering the camera separately the order form had it with lengths between 6" and 6'.
