2007 Alfa with a Weldex backup camera system. The sound works all the time but no video most of the time. The video comes on once in a while.
I have checked all connections and power.
How can I determine if it is the camera or the monitor.

Thanks in advance

Most MH rear cameras have a connection anywhere from two to five feet from the camera behind the rear cap and usually exposed to dust. Have you checked that connection?

The only way to really check them is to have the correct electronic tools or another set to plug into the system. Most problems like you describe are limited to either voltage or video cable.

Good luck.

Disconect the camera at the back and bring it up and plug in to the monitor. I had a bad line and the video kept cutting in and out. See if the camera works when you bring it up front..... I still am having problems so I ordered a whole new system with side cameras and color. Going to start putting it in this week.

Gary has a good idea,it you can connect the camera to the monitor inside the coach,you may need an adapter of some kind to make the connection(s) That will tell you if the camera is working, it it is then its a cabling problem.Should it not work it could be an intermittent monitor or camera issue.
If you have some other camera to connect,good way to eliminate the monitor.
The catch is is your BU camera an analog unit or digital? the monitor will need to see the proper format to display an image. Always that if,maybe thing!!

I had this problem on a Weldex system. I purchased a replacement cable just to check if it was it. It was, so I ran the new cable. I think it was about $1.25/ft for the cable. Not too bad for troubleshooting cost. But if it is not the cable, what do you do with the spare? For me the investment was worth it.

We have had the same problem. You should not need an adapter to test the monitor by plugging in the camera directly. Contact www.rvcams.com. I purchased a replacement cable for about $40 including shipping. Call them, but be sure to tell them your Weldex numbers. The cable listed on line is not the one needed.
