Rear view camera

[kchadw1944]

I have a 34 foot fleetwood m/h....bought it used and it didn't come with anything on the rear camera...it appears to be a fairly expensive model...color ..has a seven inch screen...plus an egg shaped module attached to the wire running from front to rear...has one on each end with a short antenna coming from it...a small red light on the front end..and a blue light on the one on the rear end...
It worked for several years...recently we noticed nothing but a blue screen and on it, it says " No Signal "....I've traced the wire and found all connections are ok...Not sure whether the problem is on the camera end or the screen end...
Don't know what kind it is either...Jeed to know how to troubleshoot this thing..

Thanks...

The "egg shaped modules" are most likely ferrite chokes which block RF interference from traveling down the wire. They're often found on computer and video cables.

Your camera probably has 12 v power to it. Check the wires for 12 v power. You could also check the video cable with a long jumper cable to test continuity.

If the wire doesn't run the length of the RV, then perhaps it's wireless.

Best way to help troubleshoot the system would be to contact Fleetwood and see what was installed at the factory. Perhaps it's original, perhaps it's been changed.

If you've installed LED or fluorescent lights, they could cause interference if it's a wireless system.
